Abstract
Flood can be considered as the most severe event that may occur at any
country. For this reason, the world most countries began to put general plans to assess the risk of failure of Dams and Barrages located along their rivers to evaluate the inundation areas resulting from failure to protect the infrastructure, human lives, roads, railways, cultivated lands and private properties. Therefore, the present research aimed to study the impact of main Barrages failure located along the Nile River (New Esna Barrages, New Naga-Hammadi Barrages and Assiut Barrages) through number of scenarios at different flow conditions. For this purpose, the combined SOBEK 1D-2D software package was employed to simulate the failure of each Barrages individually.
Twelve scenarios were tested to simulate the failure of each of Nile River main Barrages. The modeled scenarios studied the failure of each Barrage
individually at different flow conditions (Maximum passed flow discharge in
the Nile River during twelve years starting from 1995 to 2007 as well as the
emergency flow discharges). The attainable results showed the change in flow discharges and velocities, bank overtopping, flood wave propagation and the expected flooded areas resulting from the failures. The concluded results can help decision makers to asses the risk of flooding and helps to produce evacuation plans and alarming systems at each Barrage site as tools to manage the expected risks.
