1.年降水量与地表径流模关系曲线(以下简称关系曲线),就是在一个独立的集水流域内,以各个不同的年降水量作纵坐标,以与之相对应的单位面积年地表径流量为横坐标所构成的曲线。根据这条曲线,我们可以很明显地看出,在不同年降水量的条件下,地表径流量的大小。 2.在探讨该曲线在水文地质工作中的应用之前,必须简单地重复一下,在一个独立流域内水均衡的概念:
1. Annual precipitation and surface runoff modal curve (hereinafter referred to as the relationship curve), is in a separate catchment watershed, with different annual precipitation for the vertical axis, with its corresponding unit area annual surface runoff For the abscissa form the curve. According to this curve, we can clearly see that at different annual precipitation conditions, the size of the surface runoff. 2. Before discussing the application of this curve in hydrogeological work, one must briefly repeat the concept of water balance in an isolated basin:
