Lightweight, portable unmanned aerial vehicles (UAVs) or ‘drones’ are set to become a key component of a water resource management (WRM) toolkit, but are currently not widely used in this context. In practical WRM there is a growing need for fine-scale responsive data, which cannot be delivered from satellites or aircraft in a cost-effective way. Such a capability is needed where water supplies are located in spatially heterogeneous dynamic catchments. In this review, we demonstrate the step change in hydrological process understanding that could be delivered if WRM employed UAVs. The paper discusses a range of pragmatic concepts in UAV science for cost-effective and practical WRM, from choosing the right sensor and platform combination through to practical deployment and data processing challenges. The paper highlights that multi-sensor approaches, such as combining thermal imaging with fine- scale structure-from-motion topographic models, are currently best placed to assist in WRM decision-making because they provide a means of monitoring the spatio-temporal distribution of sources, sinks, and flows of water through landscapes. The manuscript highlights areas where research is needed to support the integration of UAVs into practical WRM, for example, in improving positional accuracy through integration of differential global positioning system sensors, and developing intelligent control of UAV platforms to optimize the accuracy of spatial data capture.
Assessing the ability of SWAT as a water quality model in the Lake Victoria b...Timo Brussée
There is a need for a water quality model for use in the Lake Victoria basin countries in East-Africa. The
region is characterised by data scarcity, a tropical climate and riverine, lacustrine tidal wetlands which form
an important buffer to riverine pollution of the lake. These characteristics of the basin form a challenge for
water quality models. The objective is to state the strengths and weaknesses of a potential water quality
model under these challenging conditions. This objective is executed with the soil water assessment tool
(SWAT) in a catchment of the Lake Victoria Basin as pilot area. The pilot area of the Mara river basin is
hydrologically complex containing tropical and plantation forest, savanna, grasslands, bi-annual agriculture,
shrublands and wetlands. It has varied soil types and bi-annual rain seasons
The study consist of literature research and flow simulation of the transboundary Mara river basin. The
model study aims to characterise the hydrology in the pilot area. The study includes a thorough analysis of
rainfall, stage and flow data. Model preparation steps include the use of weighted-area rainfall estimation
methods, climate model data and empirical derivation of soil input parameters. Discharge calibration
methods include multi-site calibration, by making use of an alternative objective function statistic for the
commonly used Nash-Sutcliffe Efficiency (NSE) called the Kling-Gupta Efficiency (KGE). The literature study
targets previous flow and water quality studies done in tropical or wetland areas, thereby looking to see how
these studies adapted to hydrological modelling with SWAT in tropical or wetland areas, and why theses
adaptions were made. The literature research also includes a comparison of wetland processes in SWAT
with the physical, biological and chemical processes as described in previous studies.
The Mara river basin flow simulation gave a satisfactory model performance for two out of three calibration
sites, thereby being able to give preliminary outputs on water-balance and other flow characteristics. During
research, a number of model, knowledge and data gaps were found to be critical for better understanding
the hydrological and water quality system workings in the Lake Victoria and Mara river basin. From the
model and literature study it is concluded that several issues on data scarcity and hydrological model
processes in the tropics can be overcome. These do not necessarily decrease model performance or
uncertainty in the SWAT model. However, wetland processes are oversimplified in SWAT. Modification and
coupled SWAT models yet have not been able to provide an alternative to the default model that adequately
represents the main flow, sediment and nutrients processes and fluxes that are present in Mara’s wetlands.

Application of GIS and MODFLOW to Ground Water Hydrology- A ReviewIJERA Editor
Groundwater is one of the most valuable natural resources, which supports human health, economic
development and ecological diversity. Due to over exploitation, the ground water systems are affected and
require management to maintain the conditions of ground water resources within acceptable limits. With the
development of computers and advances in information technology, efficient techniques for water management
has evolved. The main intent of the paper is to present a comprehensive review on application of GIS
(Geographic Information System) followed by coupling with MODFLOW package for ground water
management and development. Two major areas are discussed stating GIS applications in ground water
hydrology. (i) GIS based subsurface flow and pollution modelling (ii) Selection of artificial recharge sites.
Although the use of these techniques in groundwater studies has rapidly increased since last decade the sucess
rate is very limited. Based on this review , it is concluded that integation of GIS and MODFLOW have great
potential to revolutionize the monitoring and management of vital ground water resources in the future.
Presentation highlights the potential of satellite data products, modeling tools and Smart-ICT platform to assist flood-based farming to enable rural people to overcome poverty and improve food productivity while reducing water consumption.
The project demonstrates for the last two flood seasons how satellite data can detect the extent and duration of flooding in various irrigation block and the authorities can make use of such information to know when and where the flood waters are reaching the farm fields and how many days it got inundated. We have also showcased how flood forecasting tools can help downstream authorities to make operational planning including maintenance of irrigation blocks and early warning for local communities.

In this study a mathematical model used to simulate the groundwater lowering in the Ancient Babylon City, located 90 kilometres south of the capital Baghdad, Iraq. The solution proposed within this study is constructing of subground in addition to use 21 discharging wells with (45)m depth
distributed around the study area, which covers about (11) km2 Four scenarios are presented basing on the number and location of subground dams used. For each scenario, wells discharge and time of operation are varied and the results were analyzed. The results showed that installing of subground dam effects significantly groundwater elevations in the studied region and reduce time and efforts required to lower the Ancient Babylon City.
APPLICATION OF 1-D HEC-RAS MODEL IN DESIGN OF CHANNELSAM Publications
Flood occurs at Surat city frequently due to sudden release of water from Ukai dam in river Tapi. At the
time of floods in river Tapi, Surat city and surrounding regions are most affected. The city has faced many floods
since long back. Major flood event occurred in the year 1883, 1884, 1942,1944,1945,1949, 1959, 1968, 1994, 1998,
2002, 2006, 2007 and 2012. The carrying capacity of river is approximately about 4.5 lakhs cusecs (12753 cumecs) at
present. In this, stability of a segment of lower reach approximately 6 km length of Tapi river between Weir cum
causeway and Sardar bridge is evaluated for its carrying capacity and stability in response to discharge and slopes
using HEC-RAS software for past flood data. The study reach consists of 24 cross-sections. The hydraulics model,
HEC-RAS is employed to evaluate flood conveyance performance and also uniform flow computation is carried out.
In the present study existing storm drains are not only marked but based on the HEC-RAS water surface elevation
computation for various flood discharges, need of flood gates on the storm drains are also assessed. The
recommendations are done based on this study either to increase height of bank or construct a retaining wall at
certain sections along the study reach. The present study also recommends installations of flood gates on all the storm
drain outlets which are without flood gates. The width of river in no case be encroached as sections are sensitive high
floods.
Egypt is one of the biggest and affected country in Africa and Middle East, which
affected by increasing population and many developing projects. The Nile is the artery
of life to Egypt as it shares with other ten countries as it considered the longest river
by adding its tributaries which reach 6,850 km. Egypt is suffering from deficit of water
resources at the present and in the future. Modeling may be helpful in solving water
shortage problems in the Nile valley with successful future planning. Many previous
studies had applied mathematical, physical and mechanical models on Nile river basin
and studying the impact of climate change and new strategies in water resources
management and using the GIS and share decisions with al participates. In the present
research, we apply WEAP program on east Nile delta and study Sharkia Governorate
as case study as it is the third big governorate in population and it is expected to
suffering from water deficit problem, so to achieve this deficit place and amount. We
feed the program with total resources of main canals (Ismailia and Bahr Mowais) and
total demand of water from different sectors; irrigation, domestic, and industrial
water demands. then the program determines the deficit area and redistributes the
water according to demand node priorities. We concluded that the water deficit value
=11.6MCM/year occur at the end of irrigation network (San Al Hagar & Al Salheya
region) where some illegal actions done by the farmers to overcome this water
shortage.
Comparison and Evaluation of Support Vector Machine and Gene Programming in R...AI Publications
Simulation and evaluation of sediment are important issues in water resources management. Common methods for measuring sediment concentration are generally time consuming and costly and sometimes does not have enough accuracy. In this research, we have tried to evaluate sediment amounts, using Support Vector Machine (SVM), for Kashkanriver, Iran, and compare it with common Gene-Expression Programming. The parameter of flow discharge for input in different time lags and the parameter of sediment for output dhuring contour time (1998-2018) considered. Criteria of correlation coefficient, root mean square error, mean absolute error and Nash Sutcliff coefficient were used to evaluate and compare the performance of models. The results showed that two models estimate sediment discharge with acceptable accuracy, but in terms of accuracy, the support vector machine model had the highest correlation coefficient (0.994), minimum root mean square error (0.001ton/day) , mean absolute error(0.001 ton/day) and the Nash Sutcliff (0.988) hence was chosen the prior in the verification stage. Finally, the results showed that the support vector machine has great capability in estimating minimum and maximum sediment discharge values.
Determination of safe grade elevation by using hec ras case study mutha rivereSAT Journals
Abstract
Flood is a naturally occurring disastrous event causing damages, losses and destruction to property, life and environment.
Hundred millions of money are spent every year in flood control and flood forecasting. For construction of any structure near
by a water body or in between a water body and for determination of safe levels of construction to protect structure from
flood water, safe grade elevation is required.
In order to evaluate or estimate, mitigate and handle the floods, the present paper presents a methodology for assessment of flood
line to produce safe grade elevation by using River Analysis System made by Hydrologic Engineering Center (HEC-RAS)
software which is predominately used in the field of hydraulic analysis for floodplain delineation. The general parameter affecting
flood is runoff gauge, discharge, rainfall and land use as spatial data. This paper explains the use of the HEC-RAS for producing
the safe grade elevation for Mutha River from its origin at downstream side of Kadakwasla dam till Mahtre Bridge. It explains the
methodology to construct a table model and how to validate it. The methodology developed can be applied for regions if only
predominant factors affecting the flood in that region is consider, to decide the best economical safe grade elevation for the
building or structure near or on the river and would help in planning priorities prerequisites for managing flood efficiently.

DESIGN & ANALYSIS OF WATER DISTRIBUTION NETWORK MODEL BY EPANET A CASE STUDYvivatechijri
Water is one of the primary needs of all living being of world. Water supply system is a system ofengineered hydraulic and components which provide water supply. The water distribution network plays a virtualrole in preserving and providing desirable life quality to the public, of which reliability of supply is the majorcomponent. A community can only thrive if it can ensure the availability of safe drinking water for its members. Asthe population of any community increases, the demand for water also increases and imposes additional load tothe existing water distribution system. As a result, the existing water distribution system may become unreliable tomeet the demand of the increased population. In order to fulfil the water demand of the continuously growingpopulation, it is essential to provide the sufficient and uniform quantity of water through the designed network ofpipes. EPANET is computer program that performs extended period simulation of hydraulic behaviour withinpressurized pipe network. The study presents the hydraulic analysis of pipe line network of Narangi area in Virarcity using EPANET 2.0. The result obtained verified that the pressure at all junction and the flows with theirvelocities at all pipes are feasible enough to provide adequate water to the network of study area and also help tounderstand the pipelines system of the study area in a better way. The study also deals with the future demand ofthe area.
A two-dimensional mathematical, model is developed to simulate the flow regime,
of the upper part of Dibdibba Formation. The proposed, conceptual model, which is
advocated to simulate the flow regime of aquifer is fixed for one layer, i.e. the activity
of the deeper aquifer is negligible. The model is calibrated using, trial and error
method. According to the calibration process, the hydraulic characteristics of the
upper aquifer has been identified the hydraulic conductivity in the study area ranged
(60-200) m/day while the specific, yield ranges, between, (0.08- 0.45).In this research,
the obtaining of the optimum management of groundwater flow by linked simulationoptimization
model. MODFLOW packages are used to simulate the flow in the system
of groundwater. This model is completed with an optimization model which is
depending on the Genetic Algorithm (GA) and Tabu Search (TS). Two management
cases (fixed well location and flexible well location with the moving, well option)
were considered by executing the model with adopting calibratedparameters. In the,
first case the objective function is converged to a maximum value of (3.35E+5 m3/day)
by using GA, while this function is closed to 4.00E+5 m3/day by using TS. The
objective function in second case converges to the maximum value (7.64E+05m3/day)
and (8.25E+05m3/day) when using GA and TS respectively. The choice option for the
optimal location of the wells in the second case leads to an increase of 106%

2. Ph.D. Thesis Summary
o Title:- “Design Program for Integrated Improved Farm Irrigation System in Old Lands of
Delta Egypt”
o Supervisors:- Prof. Kamal Abou-El-Hassan Ali Ibrahim, and Ass. Prof. Ashraf Saad Zaghloul
o Abstract:
Managing water resources in Egypt has become a difficult task, where multiple and growing
demands are competing for a limited water supply. In order to deal with this situation, the
Ministry of Water Resources and Irrigation (MWRI) has adopted Integrated Water Resource
Management (IWRM) as official policy to improve water management in Egypt. Concepts
such as decentralization, water user participation, water quality, and water use efficiency,
have been promoted and implemented via many projects such as: the Integrated Irrigation
Improvement and Management Project (IIIMP). The main goals of this thesis can be divided
into two objectives. First objective, an analytical program, using Matlab software has been
developed to design the improved low pressure pipeline mesqa system in the old lands of
Delta Egypt. The program was calibrated with field data of two mesqas located in Kafr El-
Sheikh and El-Beheira Governorates. Good agreement was obtained between the results of
the program and the existing improved mesqas. The new program was extended to include
the design of the integrated improved low pressure pipeline marwa system. This extension is
essential to identify the impacts of the design of improved marwa pipelines on the existing
mesqa pipelines to increase the network efficiency. One of these impacts is to calculate the
required raise in the water level in the stand tank due to the improved marwa pipeline instead
of just adding an approximately two meters as used in MMHD program which will be
reflected on reducing the total system cost either in the cost of the stand tank or the pump
because the accurate required raise can be less than two meters. The new program also can
detect the optimal design velocity for the pipe network’s design under different constraints
such as maximum velocity limit, restricted height of the stand tank, combination of the
previous two constraints, and minimum total system cost. Second objective, the program
offers a design of rotational scheduling for the operation of the improved irrigation network
inside the field to ensure equity water distribution between farmers and to overcome the
problem of water shortage at the tail ends of mesqas. The rotational scheduling uses the
combined system curve technique either in case of one or two opened outlets/network. For
each opening scenario, all the control parameters such as the accurate discharge of the opened
outlets; the corresponding water level inside the tank; and pump discharge and its efficiency
are detected by the program. Also the corresponding irrigation time for each opened outlets
according to the crop pattern is calculated. The program can also determine the scenario for
minimum total irrigation time for each mesqa on the branch canal. So, the final result of the
thesis is to design and operate the integrated improved farm irrigation system in old land of
delta Egypt. (Four papers of this thesis were published).
3. M.Sc. Thesis Summary
o Title:- “Developing an Analytical Program for Solving the Analytical Equations of
Fully/Partially Penetrating Wells, Using Matlab Program”
o Supervisors:- Prof. Sherif El-Didy, and Prof. Ahmed Wagdy
o Abstract:
The main objective of the thesis is to develop an analytical program, using Matlab program,
for solving the analytical equations of groundwater wells. The equations are developed by
Theis, Hantush, Jacob, and Neuman covering confined aquifers, semi-confined aquifers, and
unconfined ones. The program saves the time and effort of calculations for solving the
complicated analytical equations. The program is a visual interacting one, but this interface is
made using Matlab program, with the advantage of reducing the probability of error in
entering data. The solutions simulate different conditions of fully/ partially penetrating wells
in steady and unsteady conditions. More understanding of the wells hydraulics has been
achieved through using the program, and it used to solve some field problems.
