Abstract
Dams play a very vital role in the economy of countries. However, in the unlikely and rare event of their failure, these may cause catastrophic flooding in the downstream area, which may result in huge loss to human life and property. This loss to life and property would vary with extent of inundation area, the propagation of flood waves, size of population at risk, and the amount of warning time available. Therefore, analysis of hydraulic hazards inundation of Delta Lands due to Aswan High Dam failure in rare conditions is presented here. This study aimed to assess the impact of such a catastrophic event on the inhabited areas downstream the Delta Barrages to Mediterranean Sea, or any urban area which may be in the path of the flood surge waves. This study based on a large amount of available hydraulic data, which were analyzed and were used as input data to numerical models; flood model, (SOBEK 1D2D) for five different scenarios. The problem has been studied by the simulations, which were performed along the River Nile Delta Branches (1D) and Nile Delta by using overland flow (2D).
The results of this study such as the inundated area of delta lands, flood depth, flow velocity and travel time of the flood waves propagations along the Damietta branch and Rosetta were calculated in order to define the time of response for emergency measures to be operated. So the size of expected damage of national main structures, (Railways, roads, airports, etc) within the extension of the study area was identified. GIS maps were prepared to evaluate the effects of the dam failure on the inundated area.
The final obtained raster maps were handled and analyzed mutually with available maps of geographic information system thus more applicable results, and suggestions of the emergency procedures were obtained. The results could put forward to a flood management plan, propose mitigation plans against inundation, and warning systems to rescue affected people and could suggest evacuation plans.
Finally, the important benefits provided by this study are the Planning of the future construction projects and new cities could be outside the boundary of inundation area.
