Abstract

The Citarum River basin has witnessed civilization in Java, Indonesia since a hundred years ago. Upstream Citarum, currently, receives pollutants and requires a morphometric study to understand its characteristics. This research aims to analyze watershed morphometrics using multi-sources data and geographic information system (GIS). Our research was located in the Cirasea watershed, West Java, known as the starting area for the Citarum River basin. Data came from multiple sources such as DEMNas, SRTM, CopernicusDEM, AsterGDEM, Topographic Maps (RBI), BBWS-Citarum, high-resolution satellite imagery, as well as field surveys to obtain accurate information. Data integration and analysis referred to a geospatial approach using QGIS. This research showed that the Cirasea watershed has an area of 366.17 square kilometers (sq km), with permanent rivers and periodic rivers reaching 106.02 km and 298 km, respectively. The Cirasea watershed has a rounded shape with 10 reaches named 1) Baleendah, 2) Cikoneng, 3) Ciparay, 4) Ibun, 5) Jelekong, 6) Kertasari, 7) Majalaya, 8) Panca, 9) Rancakasumba, and 10) Sumbersari. The watershed's flow density is 170 m per square km with a trellis pattern and a meandering level of 11.40. The Cirasea has 8 river orders and 4 oxbow lakes downstream along 3.4 km. Multi-sources data and GIS have proven to reveal characteristics accurately both in detail and actual conditions.
