Riinoff is one of the faclors t ha t can cause landslides. This phenomenon occurs in Lematang watershed especially in upstream region. The purpose of this research is t o determinerunoff t ha t occur i n LemutangHulu sub-watershed. In the analysis of runoff, LematangHulu watershed w as drvided into 5 sub-watershed, namely Sub DAS L Hulu 1 - Sub DAS L Hulu 5. The method used in analyzing this runoff is Rational one. It considers runoff coefficient, the intens i ty of rainfall and catchment area. AU parameter s runoff's calculation obtained by using spatial interpretation of satellite images for land use (C),boundary f area in the drainage (A) from analysis of DEM ( Digital Elevation Model ), and the distribution of rainfall intens i ty (I) using Algebra Average & Mononobe formula. The result show t ha t in Sub DAS L Hulu 3, one of the sub-watershed should receives extra attention be cause i t yields high runoff which is equal t o 679,8 m3 s. It may cause ftood or landslide in the future.
