| Abstract | Most of the major rivers of Nepal gets their discharge from snowmelt during the dry season, when the flows in minor tributaries, without snow-covered, are almost negligible. Therefore, the flows of snow fed rivers during the dry season are very important for water resources planning in Nepal. In the view of this, an investigation of the applicability of the TANK model for the simulation of the stream flows of a typical snow fed river in Nepal, the Dudh Koshi river was carried out. Tank model with snow component was used to simulate daily stream flows using daily temperature, daily precipitation and average monthly evaporation data as inputs to the model Automatic and semiautomatic calibration procedures were used to calibrate the model parameters. The model was calibrated using four years of data (1971-74) and verified with the two years of data)1975-76). The simulation of the monthly flows and the low flows of the daily discharge are found to be satisfactory, However, it was found that the daily discharge during the high flow were not simulated properly. Hence, the TANK model with snow component may be applied satisfactorily for the generation of monthly flows and low flows of the daily discharge in the snow fed rivers of Nepal, but the simulation of peak flows is less reliable. |
