Web-Based Spatial Decision Support System (SDSS) For Flood Risk Management In Surakarta: A Preliminary Result

Abstract

The aim of this research is to develop a web-based GIS on implementation as SDSS for flood hazard management in terms of giving information about the area, slope, land use, soil type, predict flood inundation area, and number of houses and people were evacuated when the floods in the Solo Basin area, so that expected to provide insight into the theoretical and applicative regarding the role of SDSS in flood disaster management. The processes are involved several government institution relate to their specific role and duty in the program. Therefore, the accessibility and interoperability of SDSS is important to convince that flood information is distributed well to all user concerned. Based on the explanation, web-based SDSS seem to be possible solution. The prototype shows that spatial information of risky area can be distributed widely among responsible Agencies trough web-based technology. This finding can be used to provide statistical data as well as spatial extent, distribution, location on other spatial information aspect of risk. Therefore, decision making process in flood disaster risk management can be conducted collaboratively.
