Abstract


On the basis of the water channel of the eastern plains of ecological water resource network of Handan, applying the theories and methods of soil water dynamics and groundwater dynamics, through internal and external field test and analysis, and using computer simulation and other methods, this paper does a systematic study on the discipline of water seepage in channels. What the entire paper studies are as follows:(1) The parameters of soil water movement and the movement of soil water were measured and determined by the indoor water infiltration tests of typical channels in Handan-eastern plain water network by using Hood-infiltrometer.(2) The mathematical model of soil water infiltration was established on the basis of the Richard equation of non-saturated soil moisture movement and the soil water infiltration model of channels was numerical simulated by using HYDRUS-2D programming. The comparison between the results of simulation and testing was analyzed in the paper.(3) The value of groundwater carrying and the situation of the improvement of ecological environment were calculated and analyzed combining with the groundwater status quo and information about water delivery and water distribution of network in Handan City.Nowadays, the water resources are scare seriously, but the study of this paper has given a new idea to the law of groundwater movement and a new method to the mechanism of soil water infiltration, and supported to the ecological construction in theory, and opened up a new space to the study of water conservation of agriculture.
