Analisis Sebaran Limpasan Permukaan pada Sub DAS Lesti Sebagai Pertimbangan Konservasi Hulu DAS Brantas

Abstract

The Lesti sub-watershed, which is entirely in Malang Regency, is the widest sub-watershed of the upstream Brantas watershed, which has the biggest role in contributing river flow which impacts downstream in the Sengguruh Reservoir. The current condition of surface runoff distribution in Lesti Sub-watershed is based on the latest data on rain and land use, which has not been widely discussed by policy makers. Information on the distribution and proportion of surface runoff in watershed areas is interesting to study further in order to give consideration to watershed conservation efforts. This study aims to calculate surface runoff and its distribution as a basis for policy makers to determine priority locations for conservation efforts in the Lesti sub-watersheds.
