Remote Sensing Application For The Shape Identification Of Serang Drainage Basin In Kulon Progo

Abstract

The aims of this research is to determine the shape of Serang drainage basin, Kulon Progo, DIY base
on the appearance recorded on the image of SRTM. Research method of remote sensing image
interpretation of SRTM for the determination of Serang drainage basin and then calculate the
morphometry of drainage basin in terms of the length of the main river, the width of the drainage basin,
and the around of the drainage basin by using ArcGIS software. The results of morphometric
calculations is the main river length of 27.25 km, the drainage basin area 305.404 km2, the around of
drainage basin 107.353 km. Based on these results can be calculated wide drainage basin of 11.207
km, the shape of roundness 0.33 so that the Serang drainage basin is classified as a drainage basin
with elongated shape.
