对地下水资源评价或对拟建水库水均衡计算时,常要利用到区域渗入系数。要求得一个地区的渗入系数却是相当困难的,通常使用的方法投资大、费时长、故不常被采用。本文介绍的是计算区域渗入系数较为普遍适用的相关方程。文中引进“地表控测混合流量”和“渗入盈亏系数”的新概念,并举有实例,借以阐明计算方法及对计算结果的应用。
For the evaluation of groundwater resources or the balanced calculation of the proposed reservoir water, it is always necessary to make use of the regional infiltration coefficient. It is quite difficult to obtain the infiltration coefficient of a region. The commonly used methods involve large investment and long time consuming, so they are not often used. This article describes the calculation of regional infiltration coefficient is more generally applicable correlation equation. In this paper, we introduce a new concept of mixed surface flow control and infiltration profit and loss factors, and give some examples to illustrate the calculation method and its application to the calculation results.
