摘要:
地表填洼量是水文过程分析的重要内容之一，与地表糙度密切相关。为了获得地表填洼量的估算方法，通过概化不同形式的微地形形状，推求出了相应的地表填洼量的理论计算公式，并且通过试验资料对理论公式进行检验，获得了理论填洼量与实际填洼量相应的修正系数。结果表明：理论填洼量和实测填洼量均随着坡度的增加而减小；单位坡长的填洼量随着坡长变化并没有明显变化；填洼量随着上方来水流量的增加而呈现出逐渐增加的趋势，满足相应的线性增长关系。同时分析了填洼量与糙度间关系，结果显示填洼量随着地表糙度增大而增大，二者表现为乘幂关系。
Abstract:
Surface depression storage is one of the most important parameters in the hydrological process analysis, which is closely related to surface roughness. In order to obtain the method of calculating surface depression storage, based on the generalization model of different micro topography shapes, we achieved the calculating formula of surface depression storage under different surface depression storages, and checked the theoretical formula using experimental data, obtained the corresponding real depression storage. The results showed that, with the increase of slope, the theoretical depression storage and real depression storage both decrease; the unit length of depression storage had no obvious change with slope length. With the increase of flow rate, depression storage showed the increase trend, and met a linear growth relationship. Depression storage is closely related with surface roughness, it increased with the increase of surface roughness, and can be described by the power function.
