一、地下水和降水的关系:九年来的资料分析证明,淮北地区地下水位在—般暴雨过程中的升高度δ与地下水埋藏深度h及降水量P之间,存在着下列关系: δ=K((P·h)~(1/2))~n,式中:K为系数,n为指数。因此将每次降雨后地下水位的升高度δ与降雨量P开方及雨前地下水埋藏深度h的乘积在对数纸上可以得到一根直线。二、地下水的标准退水曲线:淮北区地下水的退
I. THE RELATIONSHIP BETWEEN GROUNDWATER AND PRECIPITATION: The data analysis in the past nine years shows that there exists the following relationship between the elevation δ of groundwater table in the general rainstorm of Huaibei area and the depth h of groundwater and the precipitation P: δ = K ( (P · h) ~ (1/2)) ~ n, where K is a coefficient and n is an exponent. Therefore, after each rainfall, the elevation δ of groundwater level, the square root of rainfall P and the buried depth h of groundwater before rain can be obtained as a straight line on logarithmic paper. Second, the standard of groundwater backwater curve: groundwater in Huaibei District retreat
