US-Egypt Cooperative Research: Towards a Better Understanding of the Hydrology of Lake Nasser, Egypt

0243375 Sultan描述：该项目是为了支持纽约州立大学（SUNY）地质系Mohamed苏丹博士和埃及开罗埃及地质调查和采矿局（EGSMA）Zeinhom El Alfy博士的合作研究项目。 这项研究将建立在调查人员对纳赛尔湖西南角的初步地下水流模型的结果之上。预测分析表明，在纳赛尔湖的淤积阻抗和逐渐减少的湖泊阶段和近湖元首之间的差异，导致纳赛尔湖地表水位的普遍上升，并随着时间的推移，从湖泊的补给率下降。 PI计划开发和校准区域地下水和地表水流动模型（1）以检查其初步研究结果在整个湖泊及其周围的有效性，（2）分析研究区域内地表水和地下水之间的相互作用，以及（3）评估和量化补给率下降对湖泊水位和周边地区地表水分流方案的影响。模型将受到观测的约束（例如，岩性、物理、海拔），并通过地下水和地表水样品的地球化学数据进行推断。适用范围：主要研究者将在埃及开展美国科学家的实地工作，并在美国对埃及科学家进行联合（EGSMA/UB）数据分析和培训。 这项研究的结果将为美国和埃及双方带来共同的科学利益。这将对埃及开发西南部水资源的国家计划产生重大影响（例如，图什卡运河），并可能提供直接的应用程序，监测储存变化与时间在人工湖。 该项目由国际科学和工程办公室和地球科学司共同资助。

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.
