Abstract
The effects of digital elevation model resolutions and contour lengths on the distribution of the topographic index, a fundamental parameter for the hydrologic model, TOPMODEL, and their influence on the predic ted peak flows are investigated in this paper. A small agricultural ca tchment (3.38 km(2)) is used to determine the catchment response model ed by TOPMODEL for three rainfall events.
