| Abstract | ||
| The main objectives of the study aim at optimal exploitation of the water resources in Eastern Nile Delta region. Until now, the Ministry of Water Resources and Irrigation (MWRI) is managing water resources and the irrigation system by itself with high input of staff and high capital investment. The mission of MWRI is to ensure that Egypt's water resources are developed, allocated, used and preserved in a manner which is sustainable, equitable and efficient. The research work evaluated the water balance, the salt balance, the water quality and the management plans in the study area from August 2000 to July 2010, also, attempted a new water management plan. In this paper, the water and salt balance first executed for the Eastern Nile Delta region (ENDR). To evaluate the effect of subdividing process on water and salt balance in the region, the Eastern Nile Delta region divided into two parts according to the irrigation and drainage systems. The first one is Manzala Irrigation and Drainage System (MIDS), the second is Ismailia Irrigation and Drainage System(IIDS). Water and salt balances results showed better and stable water management policies in IIDS with water supply followed evapotranspiration (ET) demands, fairly stable narrow range water use efficiency and salt leaching process. At the contrary, ENDR affected by MIDS, both water balances results showed poor follow of ET demands by water supply, wider range of water use efficiency and adding extra salt loads process in the salt balances boundaries. The results showed that the smaller are the area, the more accurate are the water and salt balance evaluations. Also, the results of all the water and salt balances didn’t comply with MWRI mission. | ||
