Abstract
Flooding is a natural disaster that often occurs in Malaysia due to its heavy rainfall distribution. Many incidents of floods attributed to the extreme downpour caused massive problems. The capability of gauge to receive data of the torrential precipitation is affected and need to be addressed. Thus, the deployment of radar helps to retrieve better rainfall data due to spatial and temporal factors. Radar has the advantages of detecting rainfall amount with higher resolution and covers larger areas. In addition, radar can also access hilly and ungauged areas with the ability to detect cloud movement and lead to estimation of precipitation. The improved radar rainfall as quantitative precipitation estimation (QPE) has been applied in the rainfall–runoff modeling with grid-based soil conservation service curve number (SCS-CN) method and GIS utilization. The outcomes demonstrate good agreement between simulated data and observed data for selected events.
