Water resources shortage is a serious problem in our country. Facing the contradiction of water resources supply and demand, water environment deterioration and requirement of economy continuable development, Experts and scholars consider conformably that water resources continuable using must be accomplished firstly in order to implementing to continuable development of economy in our country. A main aspect is to implement continuable using of groundwater resources. Recharging groundwater by flood-water border irrigation is one of strategic measures that make groundwater continuable using.In this paper, Datong yuhe catchment has been regard as a carrier , the basic infiltration characteristics of field soil moisture , irrigation norm of flood water and irrigation technique parameters under flood-water irrigation condition have been technically researched by a method of combining room test and field test and combining test study and theory analysis. The aim is to...
