CONCEPTUAL MODEL FOR FLOOD PREDICTION USING THE TANK MODEL CASE STUDY: CIKAPUNDUNG WATERSHED

In Indonesia, there are 5,590 main rivers and 600 of them have the potential to cause flooding. The flood-prone areas covered by these main rivers reach 1.4 million hectares. When rainfall is high, runoff is the most important component of the river outlet in a watershed; subsurface currents and gro...
