- Abstract:
- We obtained the DEM of the Caijiachuan small watershed by treating the topographic map on the scale of one to thousand of the small watershed on the GIS platform TNTmips6.9. Next we extracted six son small watersheds. We calculated the topographic index of the small watershed and her sons using the program which was developed independently by us on the base of the multiple flow direction arithmetic. We obtained the frequency distributions of the topographic index of the small watersheds with the software Excel. We judged if the small watershed was similar to her sons on the hydrological response by seeing if the frequency distribution of the topographic index of the small watershed was similar to her sons. We found NO.4,5,7 sons were similar to their father on the hydrological response.
