An underground reservoir supplied with Huanghe River water

摘要

To meet the rapidly increasing water demand of the central town of Zouping County, a new groundwater field has been established, which was planed to be economic and was not significantly influenced by farming. Taking advantage of the condition that Huanghe River forms the northwest boundary of the county, a network of irrigation channels was established densely around the town and a program for underground storage has been proposed which considers to fully utilize water recharges from the channel network and the storage capacity of aquifers instead of building a new surface reservoir. Seepage-fields evolve tendencies and resources optimization modes of several schemes of water pumping are compared by three-dimension FEM numerical simulation for unsteady seepage flow. The conclusions show that the optimal schemes are: supplying water from the Huanghe River perennially, adjusting exploitation arrangement, increasing yields in the new recharge site and decreasing yields in the industrial district of the city.
