补充资料：地面滞留
径流形成过程中水流沿坡、槽运行时，部分雨水暂时蓄存于流域表面的现象。亦称流域滞留。地面滞留的水量是一次流量形成过程中退水的主要补给来源。R.E.霍顿提出，地面滞留是在洪水期间留存于地面的那部分降水,它以坡面流形式沿坡运动,在降雨终止后或成为径流或为土壤所吸收。周文德认为，地面滞留是坡面流在运行中的一种蓄水效应。事实上，这种暂时的积水现象（蓄水效应）是水流获得运动能量的必要条件，如果坡面上没有足够的积水深度，便不可能产生沿坡的水流运动。霍顿提出了坡面流(q)与地面滞留深度(h)关系如下：
q = khм
式中K 为与坡度和表面特性有关的常数；M 为与水流紊动程度有关的指数。
q = khм
式中K 为与坡度和表面特性有关的常数；M 为与水流紊动程度有关的指数。
