Application of Distributed Hydrological Model in Water Resources Assessment within Ningmeng Irrigation Area
Water resources are very important for social sustainable development. Due to the impact of hamuan activities and the climate change, which has led to the larger temporal and spatial changes of the water resoures, it is very difficult for the traditional hydrological model to adapt the requirements of the water resources study in the present changing envirnment. Therefore, the LL-Ⅲ distributed hydrological model was used to study the basin water resources and its distribution, to analyze the impact of the climate change and human activities on them, in which the information of GIS, remote sensing, DEM, land use, soil structure, land cover, etc. was used to simulate the the basin hydrological process. The model was applied to simulate the daily runoff in the Ningmeng irrigation area during 18 years, and to analyze the spatial and temporal variation of the water resources and its distribution. Based on them, the interaction between human activities especially for agricultural irrigation and the quantity of the water resources and its distribution was analyzed. The results showed that the LL-Ⅲ had truly described the water circulation mechanism and can be served for water resources analysis in arid and semi-arid area.
