Stormwater Modelling Within Three Catchments Using MIDUSS V2.25: Real Time Simulation Model To analyze stormwater within catchments
Abstract
Runoff generation within a catchment area is dependent on stormwater generated and overland flow after a precipitation for a given duration. Modelling using water resources engineering softwares becomes very import as one sorts for data, model and simulate into the future. This is able to give real time result after good work for future prediction and forecasting. This is the reason for this research work and the use of MIDUSS version 2.25 to model stormwater within three catchments. The 100min rainfall gave the maximum rainfall intensity to be 113.686mm/hr. This generated a runoff volume for pervious and impervious surface to be 268.92m3 and 239.17m3 respectively. Values of 9.606mm and 34.168mm are the runoff depths for pervious and impervious surfaces over areas of 2.8ha and 0.7ha. Stormwater volume of several depths will continue to be generated after a given duration of precipitation over impervious areas. This may lead to flooding hence the need for good hydraulic structures of adequate capacity for conveyance downstream for safety within a catchment.
