Abstract

The decline of Indonesia's quality of watershed environment nowadays requires proper management. This research was initiated to obtain the watershed morphometrics using the automatic GIS method, mainly for Flow Direction Analysis. The study was conducted in Lampir Watershed. Lampir Watershed plays a significant role in Central Java. For short, Central Java is the second most populated province in Indonesia. The analysis was achieved using a Digital Elevation Model (DEM) and processed using ArcGIS. The result shows that the Drainage density (Dd) value in the Lampir Watershed is coarse at 0.95, with an average stream length ca. 10.59. The Stream length ratio (Rt) in the Lampir Watershed increases from lower order to higher order except for Rt IV/III, but increases in the following Rt values. Infiltration capacity is the only important factor affecting the drainage texture. The length of overland flow (Lo) in the Lampir Watershed is petite (<1). The Lo result indicates that the stream will get faster to the channel and has a high potential for flash floods.
