Investigating the encroachments impact on Nile River Hydrodynamic and Morphology

Abstract

Based on the results of the present investigation, the following conclusions were deduced: 1. The implemented 1-D model is capable of elaborating the encroachment impacts by computing the water surface profile and cross section changes during 2004-2014. 2. From studying the impact of the encroachment on Reach Four it has been found that the studied areas, which belong to Beni Seuif and El Mania Governorates, located from km 25 to km 341 from El Delta Barrages, are the most areas that suffered from the encroachment in the terms of section's areas and water level. At minimum discharge: (37.7 M.m3/day) 1) The water level has been increased from 1 cm to 38 cm in some sections and it has been decreased in other section from 3.6 cm to 4.5 cm 2) The areas of sections have been changed with different percentages varying from 1% to 17%.
