Popis: Deli watershed is one of three most critical watershed in North Sumatera. Sei Petani Sub Watershed is upstream area of Deli Watershed which must be paid attention in Deli watershed management. There are some indicators in watershed management that have given attention such as hydrology, erosion, and sedimentation. This study aims to assess Sei Petani Sub watershed health on hydrology indicators (spesific maximum discharge, spesific minimum discharge, river regime coefficient, runoof coefficient and water yield). The result of this study shown that spesific maximum discharge value is 0.234 m3/s/km2, spesific minimum discharge value is 0.095 m3/s/km2, river regim coefficient is 2.34, and coefficient runoff is 0.142 whereas discharge value and water yield is shown by the time series data. The result shown that Sei Petani Sub Watershed categorized in a good condition.
