滩小关水源地地下水计算与评价

Calculation & Evaluation on Groundwater of Tanxiaoguan Source

滩小关水源地位于伊洛河口以东的黄河漫滩区,西、北、东分别与伊洛河和黄河相邻,属傍河型水源地。对埋深60 m以浅的地下水进行了计算与评价。计算方法主要采用水量均衡法、数值法评价地下水允许开采量,对浅层地下水资源保证程度进行了评价。两种方法的计算结果差别较小,结果可靠。开采量中大部分来自黄河、伊洛河的侧渗补给和洪水入渗补给,开采条件下河流入渗补给量仅占黄河最小流量的1 453分之一。因此,该水源地的允许开采量是完全可靠的。

The Tanxiaoguan water-source is located the Yellow River floodplain area of the Yiluo river estuary east,west,north,east of the area is adjacent to the Yiluo and the Yellow River,is along River water source.For calculation and evaluation of shallow groundwater in 60m depth,its uses the water balance method,the numerical method to calculate the extraction of groundwater,shallow groundwater resources to ensure the extent.The differences of calculation results of the two methods are les,which is the reliable result.Most of the extraction from the Yellow River,Yiluo lateral seepage recharge and flood recharge from river infiltration recharge is only a minimum flow of the Yellow River 1453 one,under mining conditions.Therefore,it allows the extraction of the water source is completely reliable.
