0243375SultanDescription: This project is to support a cooperative research project by Dr. Mohamed Sultan, Department of Geology, State University of New York (SUNY) at Buffalo, Buffalo, New York and Dr. Zeinhom El Alfy, Egyptian Geological Survey and Mining Authority (EGSMA), Cairo, Egypt. The research will build on the results of the investigators' preliminary groundwater flow models for the SW corner of Lake Nasser. Predictive analysis suggest that impedance of silting in Lake Nasser and gradually decreasing difference between the lake stage and near-lake heads are causing a general rise in Lake Nasser surface water level and a decrease in recharge rates from the lake with time. The PI's plan to develop and calibrate regional groundwater and surface water flow models (1) to examine the validity of their preliminary findings over the entire lake and its surroundings, (2) to analyze the interaction between surface water and groundwater in the study area, and (3) to evaluate and quantify the impact of decreasing recharge rate on the lake water level and on the surface water diversion scenarios in the surrounding area. The models will be constrained by observations (e.g., lithologic, physical, elevation) extracted from remote sensing datasets and by inferences made from geochemical data for groundwater and surface water samples. Scope: The PI's will conduct field work by US scientists in Egypt and joint (EGSMA/UB) analysis of data and training for the Egyptian scientists in the USA. The results of this study will have mutual scientific benefits for the US and Egyptian sides. It will have major ramifications for Egypt's national plans to develop its water resources in SW Egypt (e.g., Tushka Canal) and could potentially provide straightforward applications for monitoring storage variability with time in artificial Lakes. The project is funded jointly by the Office of International Science and Engineering and the Division of Earth Sciences.

项目描述：本项目旨在支持纽约州立大学（纽约州立大学）地质系Mohamed Sultan博士和埃及地质调查局（EGSMA）（埃及开罗）Zeinhom El Alfy博士的合作研究项目。这项研究将建立在研究人员对纳赛尔湖西南角的初步地下水流动模型的结果之上。预测分析表明，纳赛尔湖泥沙淤积的阻抗性以及湖段与近湖头之间的差异逐渐减小，导致纳赛尔湖地表水位随时间普遍上升，湖泊补给速率随时间下降。PI计划开发和校准区域地下水和地表水流量模型(1)以检验其初步研究结果在整个湖泊及其周边地区的有效性；(2)分析研究区域地表水与地下水的相互作用；(3)评估和量化补给率降低对湖泊水位和周围地区地表水转移情景的影响。这些模式将受到从遥感数据集中提取的观测（例如岩性、物理、高程）和从地下水和地表水样本的地球化学数据推断的限制。范围：PI将由美国科学家在埃及进行实地工作，并联合（EGSMA/UB）对数据进行分析，并为在美国的埃及科学家提供培训。这项研究的结果将对美国和埃及双方都有科学上的好处。它将对埃及开发埃及西南部水资源（如图什卡运河）的国家计划产生重大影响，并可能为监测人工湖随时间的储水量变化提供直接的应用。该项目由国际科学与工程办公室和地球科学司联合资助。
