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...
Nanjing Tidal Station is influenced by both the upstream and downstream, how to considerate synthetically the impact of the two is the key to improve the accuracy of High Tidal Level Forecasting of Nanjing Tidal Station. Based on the basic principle of equivalent water level method, design the direct method and the indirect method, to construct the high tidal level forecasting plan of Nanjing tidal...
The HBV model, which is widely used in melt snow region in Europe, has adopted the principle of water balance. It has the advantages of simple parameter, less calibrating time, and good stimulate effect. In order to work out a flood forecast in the partial-regional rain-storm problem, the article ushered in HBV model and combined the improvement of carrying on the model with GIS, adding more factors...
Soil water plays an important role in the “Four Water” transformation, which is also the direct water source to promote the growth of crop. However, soil water has been ignored for long time due to that it is difficult to observe and monitor. As a consequence, there is limited soil water observation data available for statistical analysis and modeling. This paper, after collecting and analyzing the...
