Abstract

There is a logical connection between a hydrological event in a watershed, such as flood flows with a geomorphologic structure. The purpose of this study was to calculate peak discharge and transfer and sedimentation status using two GIUH and WinTR-55 models in the Sangkhar watershed from Karkheh sub basins. First, the domain is divided into 8 sub-basins and four reachs, and then the parameters such as area, branch ratio, length ratio, Flow velocity, floor width of the waterway, channel gradient, gender and length of the route, manning roughness, tilt of the sides and sections of the waterway, type Flows, 24-hour rainfall in each sub-domain and peak Hydrograph peak values were calculated. The results showed that the GIUH model was calculated to be 52. 5% higher than the WinTR-55 model. The results showed that in S1 and S2 subfields S6 and S8, due to their mountainousness and increasing slope and Flow velocity, sediment transport capacity and Erosion are active. In S3, S4, and S5 S7 subfalls, due to low slope and low flow rate, low transmission capacity and sedimentation occurred. Also, the values of RMSE and R2 calculated for both models showed that the WinTR-55 model has higher accuracy and better performance than the GIUH model in estimating peak peak flow.
