地下水数值模拟模型应用实例分析

Analysis on Practical Example of Underground Water Mathematical Simulation

黑河下游极度干旱,黑河尾闾的额济纳绿洲主要依靠地下水维持生存。通过建立地下水二维潜流模型,模拟下游不同来水条件下绿洲核心区地下水位变化规律。模拟结果表明,黑河下游狼心山闸每年下泄7.5亿m3水量基本能满足维持额济纳绿洲现有规模的用水要求。

Heihe River has been in extreme drought situation. Ejina Oasis Area in Heihe River Basin mainly relies on underground water supply. 2 - D subsurface flow modeling has been established and water level changes in the core area of the Oasis have been simulated. The simulation result indicates that the total volume of 75 million cubic meter water from the Langxinshan water lock in the down stream of Heihe River can basically meet the water demand for sustaining the present scale of Ejina Oasis Area.
