The invention provides a watershed hydrological model design method based on a storage capacity curve and a TOPMODEL, which comprises the following steps: calculating surface runoff yield; calculating subsurface runoff yield; calculating evapotranspiration; applying a water balance equation; establishing a convergence mechanism; generating isochrones; dynamically and visually expressing soil moisture; and coupling with a Noah land surface model (Noah LSM). The method has a high simulation deterministic coefficient, is advantageous over a semi-distributed model TOPMODEL, a Xinanjiang model and distributed hydrological models such as an engineering and science summer institute (ESSI) model, a hydrologic engineering center hydrologic modeling system (HEC-HMS) model and a soil and water assessment tool (SWAT) model in the simulation of a daily runoff process and the simulation of a flood process, and overcomes the drawback that the conventional watershed hydrological model is usually inapplicable to hydrological process accurate simulation under large-scale, arid and semiarid conditions. The model of the invention can be successfully coupled with Noah LSM and improves the rainfall, soil moisture and runoff broadcasting capacity of a service weather research forecast mode, namely global/regional assimiliation prediction system (GRAPES)-mesoscale(MESO).
