KAJIAN GENANGAN BANJIR SALURAN DRAINASE DENGAN BANTUAN SISTIM INFORMASI GEOGRAFI (Studi Kasus: Kali Jenes, Surakarta)

Abstract Inundation areas caused by overflowing water from a drainage channel will create an inconvenient issue for people and its environment. Geographical Information System (GIS) is capable to present information of existing inundation areas within digital maps. This paper aims at presenting an initial assessment of a drainage channel by exploring the capability of SIG and taking Kali Jenes, Surakarta, as a case study. Inundation maps were assessed by analyzing the condition of watershed covering slope of land, land use, surface runoff, estimated inundation area, and pattern of inundation. This research resulted in digital inundation maps correspond to its time of inundation. It would be beneficial to stakeholders concerned in providing information of inundation areas faster and user friendly. Keywords: Drainage, Geographical Information System, Inundation
