- 一方面，范围Ar的“径流区”Sr包括固定范围[. . .]另一方面，由渗透性但几乎完全饱和的地形组成的可变范围的区域。Sr区的降雨完全转化为地表或近地表径流; -范围Ai的“渗透区”Si由可渗透的非饱和地形组成。形成集水区上层的桑迪土壤具有非常高的渗透能力，其渗透能力大于所有落在该集水区的降雨强度--除了极罕见的降雨。因此，落在面积Si上的雨水完全被渗透吸收，除非在非常特殊的事件中，因此不产生径流。
– the ‘runoff area’ Sr of extent Ar comprises, on the one hand, impervious areas of fixed extent [. . .] and, on the other hand, areas of variable extent composed of permeable but about completely water-saturated terrain. The rainfall on area Sr is entirely transformed into surface or near-surface runoff; – the ‘infiltration area’ Si of extent Ai is composed of permeable, unsaturated terrain. The sandy soil forming the catchment upper layers has a very high infiltration capacity, which is greater than the intensity of all the rains falling on this catchment—except for extremely rare rainfalls. Hence, the rain falling on area Si is entirely absorbed by infiltration, except during very exceptional events, and thus produces no runoff.
