- Abstract:
- In order to study of the low-flow recession law in Guizhou kasrst area, we select the Depuit-Boussinesq equation to simulate ressesion flow. Then we discuss the relationship between recession index and several kinds of terrain factor extracting from DEM. The results showed that: topographic index is directly proportional to recession index; recession index is an inverse proportion to base-flow index; Lithology and karst geomorphology has large influence on recession index and both of the two indicators not only determine runoff composition, but also determine recession’s duration and speed.
