For development of any river basin, the management of flood is an important factor. The planning for construction of detention reservoir for controlling flood is widely used all over the world. The impact of flood can be minimized by development of a detention reservoir for flood absorption for a given time. In this study, an attempt has been made for mitigation of flood considering the flood detention time and flood absorption capacities with respect to different elevations to accommodate the maximum design flood with respect to flood forecasting well in advance to minimize the flood hazards in downstream for the Kulsi river basin. Gumbel’s extreme value distribution method is used for frequency modelling to obtain the amount of flood for various return periods. The annual and monthly design floods for the month of May, June, July, August and September for return period 1000 year, 100 year, 50 Year, 25 year, 20 year, 15 year, 10 year and 5 year are estimated. The flood absorption capacities form 100.0 m to 115.0 m elevation is estimated for every 1.0 m elevation interval and accordingly detention time for the absorbed flood are also estimated using simulation.
