摘要:
AbstractLaboratory experiments, based on the theory proposed by van Heerden (1967) that net splash discharge equals the difference betweenyMiViandmiyi, whereMandYdenote downslope masses and projected distances andmupslope projected distances and masses, demonstrate that the work done by splash is a function of the slope angle to (sin a)1.9.Net discharge of sediment (q) therefore increases to (sina)0.9, It is equally a function of the susceptibility to splash erosionK, which is a complex function of the moisture content of the sands and their grain size distribution.The technique proposed for the assessment of the mean projected splash distances is rapid and gives very accurate results. When carefully applied, it can also be used for fine material like, for example, loess.The splash board technique which is currently used for many field experiments, provides none of the basic information necessary for establishing a discharge‐slope relationshi
