runoff in depth

It is necessery that the total consumptive use of water in the rotation period is equal to the total effective precipitation ( pre-cipitation minus runoff depth) in the loess hilly region.

在黄土丘陵区要求林草与农作物地在轮作周期内的总耗水量与有效雨量（降雨量与径流深之差）持平。

The depth of the lost runoff from slope and the runoff ratio increased with the increase of IR in linear function.

径流深度与径流系数均随雨强的增大而增大，表现为线性关系；

It is found by study on the runoff velocity in the layer of litter, that the runoff velocity was increasing with slope steepness and depth of runoff and was decreasing with increasing the thickness of litter.

本文研究了油松和山杨林枯枝落叶层对径流速度的影响，结果表明，它与坡度、径流深度成正比，与枯枝落叶厚度成反比。
