A grid-based distributed hydrological model BTOPMC (Block-wise use of TOPMODEL) is applied for hydrological daily rainfall-runoff simulation, which was developed from the original TOPMODEL. The runoff is explicitly calculated on a grid by grid basis and flow concentration method is Muskingum-Cunge in BTOPMC model. In order to testify the model’s application, BTOPMC model and Xin’anjiang model were applied in humid watersheds and semi-humid and semi-arid watersheds in China. The models parameters were optimized by SCE-UA method. Results show that both models are good at simulating the daily hydrograph in humid watersheds and BTOPMC model perform poor in semi-humid and semi-arid watersheds. The excess infiltration mechanism should be incorporated into BTOPMC model for broadening the model’s application region.
