Abstract

Juana River is a river in Indonesia having high vulnerability degree toward flood occurrence. The major factors causing flood in Juana River are river slope having value of 0,00001 and narrowing river channel. Therefore, the river experiences discharge capacity reduction. Juana River flood mapping is necessary to analyze extent of inundated area, especially regarding disaster risk reduction activity. This study used GIS software to process Alos Palsar image as Juana Valley topography, HEC-RAS 4.1 application for modeling the unsteady river flow, and HEC-GeoRAS 10.2 application to bridge HEC-RAS 4.1 results into GIS software. As hydraulic modeling boundary condition, this research used 52 Juana sub basin discharge having return period of 50 years and tides level at Juana Estuary. Research results showed that the extent of flood due to Juana River discharge was 37,406 hectares in both Kudus and Pati.
