Runoff estimation using SCS CN method for Kelantan River Basin

Runoff is one of the basic and crucial hydrological data which is needed in the water resources planning and management e.g. flood mitigation measures, waterways, and storage capacity and erosion control. Generally, runoff is measured or estimated by using two methods; gauged (direct measurement) an...
