Geomorphic parameter method refers to a model parameters calibration in a material area, after the parameters up to good effect, the model parameters and watershed geomorphic parameters will establish the relationship, and then using the geomorphic parameters of the ungauged area calculate model parameters of the ungauged area, then substitute model for forecasting. Disaggregation method is the use...
In order to explore the adaptability of distributed hydrological models to forecast small watershed floods, This article applies HVB model, TOPMODEL model as well as Xin'anjiang model to establish distributed hydrological models and imitate 50 floods in Fengliang River as the tributary of Hanjiang River respectively. Results show that the flood imitations of such three models achieve good effect with...
In order to explore the effection on runoff simulation of distributed hydrological model under difference grid size, this paper carry on runoff simulation with improved TOPMODEL distributed model. It is selected to verify runoff simulation under 90m, 500m and 1000m in grid-scale Separately that ten great floods and ten small floods observed data sets arrive from Tiantou River. Results show that the...
