Analysis of debris flow Kuranji River in Padang city using rainfall data, remote sensing and geographic information system

Flash flood is the most common environmental hazard worldwide. This phenomenon is usually occurs due to intense and prolonged rainfall spells on saturated ground. When there is a rapid rise in water levels and high flow-velocities of the stream occur, the channel overflows and the result is a flash...
