This document summarizes a research paper that examines issues related to waterfront redevelopment in Port Harcourt, Nigeria. Specifically, it looks at the demolition of waterfront slums, concerns of affected residents, and challenges of implementing demolition policies. It discusses the pros and cons of considering these areas as dysfunctional versus recognizing their social and economic functions. While complete sudden clearance may worsen problems, rehabilitation may not always be feasible. The document recommends a gradual phased redevelopment process to minimize negative impacts. It provides background on Port Harcourt's population growth and past government efforts to address slums. The research involved interviews and surveys of waterfront residents to understand perspectives on living conditions and awareness of redevelopment policies.

The document analyzes groundwater quality in Maiduguri, Nigeria and the impact of anthropogenic activities. 30 groundwater samples were collected from the northern (Site A) and southern (Site B) parts of the city over 2 months. Analysis found that nitrate levels averaged 13.7 mg/L in Site A and 15.53 mg/L in Site B, with some samples exceeding recommended limits. Chloride levels also varied between sites. The results indicate low to moderate current impact from anthropogenic contamination related to urbanization, waste disposal, and agriculture. Continued monitoring is needed for sustainable groundwater management.
Geotechnical investigation of road failure along ilorin ajase –ipo road kwar...Alexander Decker
This document summarizes a study examining factors contributing to road failure along the Ilorin-Ajase-Ipo road in Kwara State, Nigeria. Soil samples were collected from five locations along the road that had experienced failure and were tested for engineering properties. The results showed that the foundation materials were predominantly sandy soils with high percentages of sand. Principal component analysis indicated that sandy soils contributed most to the variability in the study area. The overall results suggested that poor foundation materials containing high sand content and poor engineering construction affected the rate of failure along the road.
Analysis of rainfall trends in akwa ibom state, nigeriaAlexander Decker
This document analyzes rainfall trends in Akwa Ibom State, Nigeria from 1992-2008. It finds that annual rainfall has generally declined, especially in the coastal south (Eket) and central (Uyo) parts of the state. This decline is more pronounced in the months of March, July and September, which are critical for agriculture. While the northern part saw an increase in rainfall, Eket and Uyo experienced rainfall declines of 58% and 65% of the total period respectively. The study concludes this declining trend could impact crop yields and the viability of double cropping seasons if it continues. Adaptation strategies like early maturing crops and disseminating climate information to farmers are recommended.
Nepal is a landlocked country located in South Asia between India and China. It has a population of nearly 31 million people and its capital and largest city is Kathmandu. Nepal has a diverse landscape ranging from Himalayan peaks to subtropical forests. The economy relies heavily on agriculture, tourism, and remittances from citizens working abroad. However, about a quarter of the population lives below the poverty line and infrastructure is lacking, especially in rural areas. Nepal has experienced some terrorist attacks in recent years but the security situation has stabilized. The country faces ongoing challenges related to poverty, development, and political disputes with neighbors.
Determination of Rainfall Characteristics and Soil Water Index for Debris and...IRJET Journal
This document summarizes a study that determined rainfall characteristics and soil water index associated with debris and mud flows in Cameron Highlands, Malaysia. The study found that debris and mud flows occurred most frequently during the Northwest Monsoon and had an average soil water index of 61. Specifically, 65% of events were associated with low intensity, prolonged rainfall (>80mm over 24 hours), rather than high intensity, short rainfall as defined by previous guidelines. The soil water index can help forecast debris and mud flow risk in Cameron Highlands.
GENERATION OF IDF CURVES IN ARID AND SEMI-ARID AREAS: CASE STUDY HURGHADA, EGYPTIAEME Publication
Intensity-Duration-Frequency (IDF) curves are commonly used in water resources projects and hydrological analyses. One of the most important requirements for creating IDF curves is the actual distribution of rainfall intensity during the period of rainfall, but usually short-duration rainfall records are rare in arid regions while daily rainfall data are available. Hydrologists can generate short-duration rainfall data from daily rainfall data through using the Natural Resources Conservation Service (NRCS) standard synthetic rainfall distributions. The main purpose of this paper is to show the procedure to be followed in developing the IDF curves using the daily rainfall data recorded at the Hurghada weather station. Frequency analysis of the observed rainfall records was performed using HyfranPlus software. The gamma distribution is the most widely accepted probability distribution in this research.

An attempt has been made to study the variability of seasonal and annual rainfall for a period of 25 years (19912015) for the upper Cauvery portion which has five districts. It can be observed that the average annual rainfall for every five years considered range from 800 to 1200mm for more than 45 percent of the area upto 2010 and from 2011-2015 it has been reduced to less than 35 percent and the percentage of area for which the rainfall range was less than 800mm was increased to 28.39 percent which was less than 14 percent from 1991-2010. The maximum portion of the area had average post monsoon rainfall between 100mm to 200mm has been from 1991 to 2010. And from 2011-2016 the maximum portion of the area has a average post monsoon rainfall less than 150mm. Some parts of Hassan, kodagu and chikkamangalore districts portions in the study area has average annual rainfall above 2000mm where as mandya district portion in the study area has annual rainfall less than 800mm and in mysore district average annual rainfall ranges from 800mm to 1500mm.

Characteristics and Resource Potentials of Nigerian AtlanticDr. Amarjeet Singh
This paper presents an updated understanding of the
Nigerian Atlantic waters in terms of the offshore characteristic
and the potentials that these characteristics provide for the
people of the nation and the continent at large. The wind,
wave, swell and current data studied were provided by Shell
Nigeria for some periods between1979 and 1983.General
characteristic consideration of wind, wave, swell and current
is made for the Nigerian Atlantic waters and in particular
Bonny Offshore, Forcadoes Offshore, Asabo Offshore and
Bonga Offshore. Inference from the results in terms of use of
the Atlantic for renewable energy sources and marine food
production based on a proposed offshore technology is
described. It is noted that the Nigerian Atlantic is relatively
mild and benign with low average velocity of 0.3 m/s running
at about 3 meters above ocean bottom. This paper further
discusses efforts made to reinvent the use of vertical axis
turbine for use in such low underwater current velocities of
0.3 m/s which is perhaps the least flow velocity of ocean water
in the world.
TEMPORAL MAPPING AND MONITORING DYNAMICS OF PANDU RIVER UTTAR PRADESH USING R...IRJET Journal
The document analyzes the temporal mapping and monitoring of dynamics in the Pandu River in Uttar Pradesh, India using remote sensing and GIS techniques. Six reaches within the 242 km stretch of the Pandu River were studied by comparing sequential changes in the river channel between 1975-2020. Significant changes in migration patterns were found, with some reaches experiencing over 100m of lateral migration. Point C near Mavaiya village showed multi-directional migration, with four distinct channels migrating between 64-84m between 1975-2020. The study concludes that continued unchecked migration could impact agricultural lands and settlements near the river. Remote sensing allows efficient monitoring of the river's changing dynamics over time.

This document summarizes a study that used remote sensing and GIS techniques to monitor changes in wetlands along the Pandu River in Uttar Pradesh, India between 1975 and 2020. The study mapped wetlands using topographical maps from 1975 and Landsat satellite imagery from 2010, 2013, 2015, and 2020. It found that the number of wetlands decreased from 1258 covering 1345.72 hectares in 1975 to 589 covering 1127.83 hectares in 2020, representing a long-term decline in wetland area over the 45-year period. Changes in rainfall levels were found to influence interannual variations in wetland extent. The created database of wetlands over time can help inform local water and land management

Hydroclimatological assessment of Jawi River Basin, Malaysiaijtsrd
A pilot investigation is being conducted to evaluate the current hydroclimatological condition of the Jawi River Basin, Malaysia. The river basin is reported to face physical changes in the near future. The basin area is located in the northern part of Peninsular Malaysia, which lies near to the equator. In this analysis, local climatology information was used since 1990 until 2010 from the Meteorological Office. The design rainstorm intensity was derived from DID Hydrological Procedure No.1, while the Hydrological Procedure No. 12 was used to compute low flows based on regional frequency analysis. The climate of the river basin reflects the equatorial climate with some monsoonal effects. Generally, the highest mean rainfall occurs in the month of October and the lowest rainfall occurs in the month of January. The 7 day low flow value for the basin is about 0.062 cubic meter per second cumecs . This means that the river basin should maintain the stream discharge at least 0.062 cumecs or above to prevent any adverse ecological impacts on the waterbody and its ecosystem.

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

----------------------------------------------------------------ABSTRACT-----------------------------------------------
Effort is here made to observe and note the spread of RTA frequencies based on the period of occurrences. The
classification was based on two distinctive seasons of wet and dry. Effects of religious festive seasons on road
traffic accident occurrence were also considered in the paper. A record on Road Traffic Accidents (RTAs)
frequency on the study route was analysed under temporal variable of festivals and seasons against the total
cases of accidents covered by the study. To estimate the effects of each of the temporal variables on accidents,
one way analysis of variance ANOVA was used at 0.05 level of significance at 95% confident intervals, from
which a decision to accept or reject the result was made. It was revealed amongst others that road traffic
accidents is high during wet season throughout the four years of study spanning 2007 to 2010. It is
recommended that vegetation growth and agricultural activities, which are fully alive during the rainy season
along the main road, should be prohibited, because they obstruct motorists from clear visibility.

I. INTRODUCTION
The word temporal is derived from Latin-Greek word Tempus (meaning time). Temporal has to do
with time as opposed to entity, earthly life as opposed to heavenly existence and time as opposed to space.
(Richard, 1986). He further defined time as a period during which event or a data based on fact was or will be
valid in modeled reality. For instance, according to him, as of December, 2011, ISO/IEC 9075 Data Base
Language was launched.
Spatio-temporal relates to space and time together. It has both the spatial extension and temporal
duration. In the same vein, space-time is a four dimensional frame, consisting of three dimensions in space and
one dimension in time used especially in relativity theory as a basis for coordinates system for identifying the
location and timing of objects and events (Encarta,2009). This paper however, focuses on identifying the
temporal elements that cause road traffic accidents along Kaduna – Zaria Expressway in Kaduna State, Nigeria.
This is with a view to provide reliable empirical data for government agencies, which will not only update what
already exist but would also facilitate more efficient management, rehabilitation and administration of the study
route
The spread of RTA frequencies is based in this paper on the periods of occurrences. The classification
was based on two distinctive seasons of wet (Mar/April through Sept/Oct and dry seasons (Nov to Feb) of every
year, religious festive periods especially during Easter (15th
Mar-15th
April), Ed-Fitr (20th
Aug-15TH
Sept), Ed-
Kabir (15th
Oct-15th
Nov), and Christmas (15th
Dec-10th
Jan) of every year, days of week and months of year
spanning 2007 and 2010.
The Sector Commander of Federal Road Safety Corps (FRSC) Kaduna State Sector Command, Mr.
Chidoka had in October, 2009, pointed out to some media organizations such as; Nigeria Television Authority
(NTA), Desmimms Independent Television (DITV), African Independent Television (AIT), and Capital TV
during EMBER Months (Last quarter of the year) campaign against road traffic accidents that amongst the
major causes of road accidents along Kaduna-Zaria expressway are; road obstruction by trailers, U-Turns,
feeder roads and the general attitudes of road users. Kaduna – Zaria expressway is among the busiest routes in
Nigeria, most especially, during yuletide periods of Easter, Ed-Fitr, Ed-Kabir and Christmas and also, the
periods of dry and rainy seasons. These results into traffic congestions thereby, causing road traffic accidents on
frequent basis, a situation that needs to be arrested because of its negative effects. Though, there could be many
ways and methods of checking and reducing road crashes, remote sensing and Geographic Information System

(GIS) are the most viable methods as they can be used to identify and at the same time analyse different
variables that cause road mishaps. The synoptic view of remote sensing is also an added advantage in this
direction. Against this background, SPOT 5 imagery of 2005 with the aid of GIS techniques was employed to
generate the required data for this paper.
II. LOCATION OF THE STUDY AREA
The study route is in Kaduna State of Nigeria and passes through three local government areas of the
state: Kaduna North, Igabi and Zaria. It cuts across latitudes 10o
30’N and 11o
10’N, and longitudes 7o
20’E and
7o
50’E. The whole area through which the expressway passes is in the northern part of Kaduna state, Nigeria
and equally shares boundaries with Kaduna South, Chikun, Soba, Kajuru, Giwa and Birnin Gwari local
government areas of the state. ((Figs 1and 2)

The study route experiences the tropical continental climate. It is characterized by two distinct
alternating wet and dry seasons. The rainy season usually begins from March/April and runs through
September/October. The rainfall amounts falls between 1100 - 1300 mm. The rainfall type is convectional with
a single regime of maximum peak, which usually occurs in August/September at a stretch (Parkman
International Studies, 1997). At the period of peak rainfall, water wash away the protection by the edges of the
road and improper or absence of bracing or embankment leads to the breakage of the road edges. Also, water
seepage beneath the road soil leads to softening and losing the soil compaction. This leads to road depression
and undulating surfaces due to pressures exerted by vehicles. Thus, creating opening (cracks, potholes and
breakages), which eventually results into road traffic crashes.

III. ROAD NETWORK OF THE STUDY AREA
The road network of the study area is classified as major road. It was duallized between 1988 and 1992
by the president Gen. Ibrahim Badamasi Babangida led military government with several feeder roads linking
the expressway at various locations. Notable amongst these feeder roads are the Zangon Aya road, Kangimi
links at Sabowa and Sabon Birni road. The study route which extends up to 73.96km long has several
characteristics such as sharp bends, bridges, undulation and U-turns. The study route is depicted in fig 3 below.

IV. METHODOLOGY
The record on RTAs frequencies on the study route was analyzed under temporal variable of festivals
and the seasons against the total cases of accidents covered by the study. The result of analysis from ANOVA at
0.05 level of significance and 95% confident intervals provided an impetus from which decisions were made.
V. RESULTS
EFFECTS OF SEASONAL CHANGES ON ROAD TRAFFIC ACCIDENT OCCURRENCES.
A brief background of the weather and climatic characteristics of the study area is reflected in section
II. The relationship between the total cases of road accidents and the frequencies recorded against each of the
variables of wet and dry seasons was established as shown in Table 1. The graphical presentation is also shown
in figure 1
TABLE 1: Distribution of RTAs Over Wet And Dry Seasons
Source: Field Analysis
Figure 4: Distribution of Road Traffic Accident Frequencies over Wet and Dry Seasons along Kaduna-Zaria Expressway
Figure 4 indicates that road traffic accidents is high during wet season through out the four years of
study spanning 2007 to 2010. Also, the occurences of RTAs increased in 2008 and decreased in 2009, while in
2010, it rose again due to seasonal variations of climatic elements in the region.
To test the level of significance of wet and dry seasons and the frequency of RTAs occurrence over the
period of study, one way analysis of variance was applied at 0.05level of significance at 95% confident
intervals. The result revealed that the calculated value given is 0.263 as against acceptance value of 0.05.
Therefore, there is no significant difference between both wet and dry seasons with the frequency of occurrence
of road traffic accidents along Kaduna-Zaria expressway.
Also, despite the insignificant nature of seasonal variations in accident causations, the range values fall
between minimum and maximum of 48 and 93 for wet season and, 36 and 70 for dry season respectively. In the
same vein, the test result indicated the mean value of 68.75 and 53.75 in wet and dry season respectively. The
result is presented in Table 2.

Effects of Religious Festive Seasons on Road Traffic Accidents Occurrence.
The study revealed that religious festivity is among the period, under which road accident frequencies
record used to be high due to the fact that the rate of travels used to be intensified. Four major different periods
have been identified under this factor and they usually occur at different times of the year, even though, some
remain fixed to particular dates, others are not (fixed) but usually within the ranges given below. The periods
identified in this paper are:
i. Easter (15th
Mar-15th
April)
ii. Ed- Fitr (20th
Aug-15thSept)
iii. Ed- Kabir (15th
Oct-15th
Nov)
iv. Christmas (15th
Dec-10th
Jan)
From the variables captured above, the total number of RTAs against each period was analysed within the
period of study, 2007 to 2010. The data is depicted in Table 3 and figure 2 below.

frequencies in the year. In 2009, Ed-Kabir tends to be slightly higher than Christmas and Ed-fitr was also
slightly higher than Easter period. From the forgoing, therefore, it is clear that most of the RTAs recorded along
the study route in the four years under review took place during Easter and Ed- Kabir periods. This was then
followed by Christmas and Ed- Fitr periods.
In order to estimate the significant difference between the temporal variables and the festive period of
religious activities such as Easter, Ed-Fitr, Ed-Kabir and Christmas with corresponding frequency of road traffic
accidents spanning the period 2007-2010, a bi-variant statistical testing was used via statistical software for
social sciences (SPSS) in which one way ANOVA applied. Findings from the test revealed that festival as a
factor with four set of identified variables is not statistically significant at 0.817. Hence, there is no relationship
between the frequency of occurrence of road traffic accidents and each of the variables of religious periods of
celebration. The test result is presented in Table 4.

Figure 6 presents the analysis of RTAs by days of week over the period of four years and it revealed
that in 2007, the occurrence rate was generally lower than the presiding three years. In 2008, RTA rose and
dropped a little bit in 2009 and rose again in 2010. Daily analysis revealed that, RTAs are more on Saturdays,
Sundays, Tuesdays, Thursdays, and Wednesdays. This coincides with market days of the settlements along the
route such as Katabu– Saturdays, Lamban Zango –Mondays, Kawo-Tuesdays, Birnin Yero-Thursdays, and Jaji-
Fridays. Following from the above, road traffic accidents occurrence is fluctuating along the route with high
frequencies during week end periods.
Figure 7: Analysis of Road Traffic Accidents by Month over the Period of Four Year.
Fig 7 revealed that RTAs were low in 2007 due to the inadequate record from the relevant authorities with highest
range of increases in the month of December. In 2008, it rose in the months of February through June and dropped in
October and rose again in December. In 2009, the highest range was recorded in the month of September, followed by July
and December. Also, in 2010, the occurrence rate rose from the months of March to April, June, July, August, September,
November and December with the highest rate of increase in the months of April, December and November respectively.
The data from which the graph was plotted is shown in Table 6.

VI. QUESTIONNAIRE ADMINISTRATION
Results of structured questionnaire revealed that255 respondents opined that 57.7% of road traffic
accidents occur during festivity periods on yearly basis. 136 respondents were with the view that 29.1% of the
road accidents were influenced by heavy rainfall. (Table 7). In such a situation, motorists find it difficult to drive
properly as a result of invisibility and running water may cover certain areas of road surface. The road could
therefore, be slippery. Another important effect of rains on the route is the appearance of luxuriant vegetation on
both sides of the express. The road sides are also busy with farming activities and these obstruct visibility of
motorists along the route especially at the curves. Against this backdrop, it is here recommended that vegetation
growth and other agricultural activities along the study route especially at the bends should be prohibited in
order not to create road accidents blind spots and impaired motorists from clear visibility from at least 100
metres. This vegetation clearance should be done by the department of forestry and livestock under the Federal
Ministry of Agriculture.
Table 7: Period of Frequent Occurrence of Road Traffic Accident
On the other hand, 316 respondents argued that 67.8% of RTAs occurred during the day especially the
rushing hours of between 0700 hrs- 0900 hrs in the morning and 1500 hrs- 1700 hrs in the afternoon. RTA
frequencies in the night are lower compared to that of the day (Table 8).

VII. CONCLUSION
Effort has been made to observe the spread of RTA frequencies based on the periods of occurrences.
The classification was based on the two distinctive seasons of wet and dry periods and religious festive seasons
especially during Easter, Ed-Fitr, Ed-Kabir, Christmas of every year, days of a week and months of the year
spanning 2007 and 2010. The result of this paper amongst others revealed that road traffic accidents is high
during wet season throughout the four years of study.
The prone accident religious festive seasons have been identified to be Easter, Ed- Kabir, Christmas
and Ed- Fitr. This has been attributed to the fact that rate of travels used to be high. People tend to go to their
father homes to celebrate these festivals. Wet season also do record high rate of accidents on yearly basis. This
is partly due to road floods and slippery nature of tare during rains. As earlier pointed out, vegetation growth
and agricultural activities along the study route should be prohibited.
