摘要

This paper investigates the development of Nile River islands in the first reach which extends between Aswan and new Esna barrages. A wide range of data compiled and used in this investigation which include produced maps in 1939, 1982 and 2003, and hydrological data. Compiled data drew a complete picture for up-to-date information on morphological changes since 1939. The analysis indicated that islands length; thus, area has reduced since 1939. Also, islands tend to reshape by elongating. The reduction in area is attributed in part to the merging of islands in either bank and adjustment of the river to the new flow conditions after the operation of High Aswan Dam. El-Mansouria Island which is the largest island in area was focused on. Recent human interferences accelerated the merging of island in the west bank. Consequently, river morphology has changed around the islands.
