THE MERIT OF GPS SURVEYING TECHNIQUE FOR HYDROGRAPHIC PROJECTS AND STUDYING RIVER SEDIMENTATION

摘要

Monitoring the river sedimentation is of importance for studying the behavior of the River Nile and Lake / Nasser. Modern Remote Sensing Techniques (RS) are capable of detecting the periodical changes of the river sedimentation within a certain depth. To generate an accurate longitudinal profile for the Nile Basin, a differential global positioning system (DGPS) accompanied by an echo sounder is utilized. To figure out the river sedimentation problem properly, it is a must to store, retrieve, and analyze the acquired data. A powerful GIS system is needed. This paper is an attempt to provide an integrated system for continuous updating and recording the updates in the River Nile.
