Intensity-Duration-Frequency Curves and RegionalisationAM Publications
Storm sewers make up a large percentage of drainage system in an urban setup. The design of these
components are based on rainfall intensities of a specific design period for that location. These can be derived from
intensity-duration-frequency (IDF) relationship. These IDF relationships are derived from historical rainfall, using
an extreme value distribution for maximum rainfall intensity. In the present study the IDF curves and parameter
regionalisation were studied for various kinds of basins. These equation parameters can be then used to understand
the spatial variation of rainfall intensity in the study area. The parameter contour maps subsequently generated using
various interpolation method are then used for plotting IDF curves for any ungauged station in the basin.
On March 11, 2016, ICLR held a Friday Forum workshop entitled 'Mapping extreme rainfall statistics for Canada', led by Dr. Slobodan Simonovic of Western University.
Climate change is expected to increase the frequency and intensity of extreme rainfall events, affecting rainfall intensity-duration-frequency (IDF) curve information used in the design, maintenance and operation of water infrastructure in Canada. Presented in this lecture are analyses of precipitation data from 567 Environment Canada hydro-meteorological stations using the IDF_CC tool. Results for the year 2100 based on Canadian climate model and an ensemble of 22 GCMs have been generated. A spatial interpolation method was used to produce Canadian precipitation maps for events of various return periods. Results based on the Canadian climate model indicate a reduction in extreme precipitation in central regions of Canada and increases in other regions. Relative to the ensemble approach, the Canadian climate model results (a) suggest more spatial variability in change of IDFs, and (b) the ensemble approach generated generally lower values than the Canadian climate model.

Derivation Of Intensity Duration Frequency Curves Using Short Duration Rainfa...Mohammed Badiuddin Parvez
The estimation of rainfall intensity is commonly required for the design of hydraulic and water resources engineering control structures. The intensity-duration-frequency (IDF) relationship is a mathematical relationship between the rainfall intensity, the duration and the return period. The present study aimed the derivation of IDF curves of Yermarus Raingauge Station of Raichur District with 19 years of rainfall data (1998 to 2016). The Normal Distribution, Log Normal Distribution, Gumbel distribution, Pearson Type III Distribution and Log Pearsons Type III Distribution techniques are used to Find the rainfall intensity values of 2, 5, 10, 15, 30, 60, 120, 720, 1440 minutes of rainfall duration with different return period. Chi Square test was conducted to find the goodness of fit the short duration IDF using daily rainfall data are presented, which is input for water resources projects.
ASSESSING THE EFFECTS OF SPATIAL INTERPOLATION OF RAINFALL ON THE STREAMFLOW ...civej
Precipitation within a river basin varies spatially and temporally and hence, is the most relevant input for
hydrologic modelling. Various interpolation methods exist to distribute rainfall spatially within a basin.
The sparse distribution of raingauge stations within a river basin and the differences in interpolation
methods can potentially impact the streamflow simulated using a hydrologic model. The present study
focuses on assessing the effect of spatial interpolation of rainfall using Theissen polygon, Inverse distance
weighted (IDW) method and Ordinary Kriging on the streamflow simulated using a physically based
spatially distributed model-SHETRAN in Vamanapuram river basin in Southern Kerala, India. The
SHETRAN model in the present study utilises rainfall data from the available rain gauge stations within the
basin and potential evapo-transpiration calculated using Penman-Monteith method, along with other input
parameters like soil and landuse. Four years of rainfall and evapo-transpiration data on a daily scale is
used for model calibration and one year data for validation. The performance of the different spatial
interpolation methods were assessed based on the Mean Annual flow and statistical parameters like NashSutcliffe
Efficiency, coefficient of determination. The ordinary kriging and IDW methods were found to be
satisfactory in the spatial interpolation of rainfall.
As basic data, the reliability of precipitation data makes a significant impact on many results of environmental applications. In order to obtain spatially distributed precipitation data, measured points are interpolated. There are many spatial interpolation schemes, but none of them can perform best in all cases. So criteria of precision evaluation are established. This study aims to find an optimal interpolation scheme for rainfall in Ningxia. The study area is located in northwest China. Meteorological stations distribute at a low density here. Six interpolation methods have been tested after exploring data. Cross-validation was used as the criterion to evaluate the accuracy of various methods. The best results were obtained by cokriging with elevation as the second variable, while the inverse distance weighting (IDW) preform worst. Three types of model in cokriging were compared, and Gaussian model is the best.

Mapping Gradex values on the Tensift basin (Morocco)IJERA Editor
The aim of this study is to elaborate the cartography of Gradex parameter used in the Gradex method for estimating flood peaks in order to size hydraulic structures. Map of spatial variation is elaborated using the geostatistical method of kriging. Several reference functions (exponential model, spherical, linear, Gaussian and cubic) were used for modeling the kriging variogram. Cross-validation enabled a comparison between the results of these models and choice of spherical model with anisotropy and trend fit by a second-order polynomial as the most suitable. The use of available series of annual maximum daily rainfall recorded at 23 rainfall stations, distributed over the Tensift basin, led also to develop the cartography of standard prediction errors‟ values associated to the predicted parameter for each point of Tensift basin. These errors vary from acceptable values (16.8%) to very high ones depending on the density of the rainfall stations at the desired site.
In developing accurate hydro geomorphological analysis, monitoring, ability to generate information in spatial and temporal domain and delineation of land features are crucial for successful analysis and prediction of groundwater resources.

ABSTRACT: This study uses different interpolation techniques to predict rainfall intensity at locationsthat are not directly located near a rainfall gauges. The goal of being able to interpolate the rainfall intensity is to study its impact on traffic crashes. To perform the study, a collection of rainfall gauges in Alabama were used as subject locations where rainfall intensity was predicted from surrounding gauges, while also providing validation data to compare the predictions. Essentially, the actual rainfall intensities at existing gauges were interpolated using nearby gauges and the results were analyzed.The interpolation techniques used in the study included proximal, averaging and a distance weighted average. The results of the study indicated that none of the interpolation methodologies were sufficient to accurately predict the rainfall intensity values any significant distance from the actual gauges.

Determination of homogenous regions in the Tensift basin (Morocco).IJERA Editor
The aim of this study is to determine homogenous region in the Tensift basin within which the hydrological behavior is similar. In order to do this we used two methods: The Principal components analysis on the monthly precipitation registered at the 23 rainfall stations. This resulted in setting apart 4 groups of stations. The second method is analysis of land use map, geological map, pedagogical map, vegetation map and slope map of the studied area. This method allowed us to delineate 4 homogenous areas. The two methods yielded complementary results and the superposition of groups and regions obtained allowed us to retain 4 homogenous regions corresponding to 3 groups of stations.

POSTER
ABSTRACT
Apulia Basin Authority (AdBP) is actually carrying out an advanced and complex study for evaluating flooding areas
of downstream reach of Ofanto, one of the most important river in Southern Italy. The performed analysis is strictly
related to a reliable definition of the hydraulic risk map in order to plan efficient hazard management actions. Due
to the geo-morphological characteristics of the selected river branch – that presents a length of about 36 km from
the Roman bridge, close to Canosa city, to the sea outfall –- this activity represents an interesting case study for
the contextual use of modern technologies in topographic data management and hydraulic computation. The
geometrical model used for the hydraulic simulation was created using input data coming from airborne laser
scanning (LIDAR), which generates 1 m cell-size Digital Surface Model (DSM) and Digital Terrain Model (DTM), that
were integrated with high-resolution digital orthophotos. The hydraulic simulation was developed adopting a mixed
1D/2D scheme, where one-dimensional model within the levees and two-dimensional model outside were used.
Simplified model for estimating friction factor distribution within the floodplain area was adopted.

Integrated Approach of GIS and USLE for Erosion Risk Analysis in the Sapanca ...theijes
The primary objectives of this study is to establish a Geographical Information System (GIS) for soil loss based upon the Universal Soil Loss Equation (USLE) method, and to determine erosion risk zones in the Sapanca lake watershed. In this study, rainfall erosivity (R) factor was computed from monthly and annual precipitation data of six methodological stations. Soil erodibility (K) factor were extracted from soil map by the Ministry of Food, Agriculture and Livestock. Land cover and management (C) factor were derived from Landsat TM imagery and from Statip 2009 map. Topographic (LS) factor was interpolated from a digital elevation model (DEM). Support practice (P) factor was assigned a value of 1 due to lack of support practices in the watershed. The study indicated that the method can be reasonably used for soil erosion risk analysis in the Sapanca Lake Watershed, and also moderate and highly eroded areas associated with new settlements and bare lands since new settlers either cleared of native forests or used intensively for agriculture. Such analysis is essential for water management practices, specifically identification of critical risk zones for investigating watershed management strategies to achieve management goals.
Drought Vulnerability Modeling for Georgia - Rebecca PeoplesRebecca Evans
For my final presentation in my Hydrology class, I created a Drought Vulnerability Model for the state of Georgia. In measuring the potential for drought, we can have actionable prevention and responsible water usage changes. Taking into factor, precipitation, temperature, crop water consumption, ground water wells, land use, slope, soil type and geology of Georgia, we can effectively model potential areas in Georgia that would be vulnerable for drought.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The use of multi and hyperspectral remote sensing systems, combining various
remote sensing, insitu data, and models (Metternicht, Zinck, 1998, Mathieu et al,
2007, De Jong et al, 1999) makes possible automated classification of eroded
lands and determination of soil erosion distribution of in agrarian landscapes.
The creation of up-to-date soil erosion control system using the data of the
Earth's remote sensing becomes urgent.
The aim of our research is the development of modern indicators for this
system based on satellite and in-situ data to determine the soil erosion and
to assess soil erosion of test farmlands

and method Results Conclusion
The method of integrated assessment of land degradation using GIS / RS Technologies is based on the
integrated index of soil erosion degradation, which is calculated by three main indicators: the type of degradation
(linear or plane); the spatial extent of an identified type of degradation; rate of degradation and use the satellite
data with high spatial resolution, thematic and cartographic information and supporting thematic
information on the characteristics of the soil cover.

Introduction Materials
and method Results Conclusion
The use of up-to-date remote sensing and geoinformation
technologies enables to obtain the accurate and up-to-date
information on the state of soil cover at various spatial levels.
The decision tree for logical model of soil erosion determination
and assessing, based on the merging of remote sensing data of high
spatial resolution with in-situ data is proposed.
The possibility of soil water erosion assessment and classification
using regression models is proved with the accuracy of 85%.
The results of erosion process risk assessment using remote
sensing are the basis for the planning and implementation of the anti-
erosion measures to optimize the structure of agricultural landscapes
and land use systems
