MODELING RUNOFF RESPONSE TO LANDS COVER AD RAINFALL SPATIAL VARIABILITY IN SEMI-ARID WATERSHEDS

摘要

Hydrologic response is an integrated indicator of watershed condition, and significant changes in land cover may affect the overall health and function of a watershed. This paper describes a procedure for evaluating the effects of land cover change and rainfall spatial variability on watershed re- sponse. Two hydrologic models were applied on a small semi-arid watershed; one model is event-based with a one-minute time step(KINEROS), and the second is a continuous model with a daily time step (SWAT).
