Improved watershed runoff estimation using radar-derived rainfall in Peninsular Malaysia

In traditional hydrologic and water resource applications, rain gauges are the commonly used rainfall measuring device. Normally these rain gauges are installed at convenient locations. Rain gauges provide direct rainfall measurements over small areas. Malaysia is a humid tropical country with more...

Malaysia is a humid tropical country with more than 60% of land area covered with forest.
