RESEARCH OF WATER AND SALT DYNAMIC PREDICT IN LIUGOU IRRIGATED REGION

Li Tongbin ;Lin Shanshan(Dep .of Hydrogeology and Engineering Geology)  
On the basis of research and analysis of the geological structure and characteristics of water and salt movement of Liugou irrigated region,a coupling modelhas been established to predict cumulated salt law in ground surface,On the model, thecumulating process of salt in surface and interior features is described bv randomtranstering function model of solute movement and definite model.The model has beenused to predict cumulated salt quantity under various depth of water table. It will laydown foundation for the design of optimal mining plan and salification control.
