Rainfall-Runoff simulation using geostationary satellite rain rate in a small mountainous watershed

摘要

Satellite-derived rainfall can be a potential source for flood detection and monitoring in ungauged watersheds. This study investigated the hydrological utility of satellite-derived rainfall through rainfall-runoff modeling. The results showed that the COMS satellite rainfall led to large underestimation in runoff discharge indicating that a preprocessing scheme such as bias correction or adjustment prior to use of hydrological applications is required.
