Lamination method of flood wadis and projection of the laminated flood hydrograph

Abstract

The catastrophic floods in semi-arid areas are often caused by floods storm that occur at any time during the  year, including the hot season. The prevention of these floods could be done by the construction of small dam  hills. This requires the control of theoretical concepts hydrological sizing, especially the hydrological structure  to evacuate floods. We suggest a method to calculate the optimal regulation flow of the flood and also the  development of a direct calculation formula of a laminated maximum flow. The analysis of the hydro graph’s analogy at the input and the output of the dam, allow searching the dependencies between their  characteristics. Knowing the characteristics of the hydrograph flood of the project and the reserved capacity  for the amortization of the flood, we can directly determine the laminated maximum flow and project the  hydrograph of the laminated flood.
