Tight coupling of SFlood and ArcView GIS 3.2 for flood risk analysis

Abstract

This paper describes the development of an Arcview GIS extension namely SFlood.avx to integrate the SFlood hydraulic and sediment transport model (modified version of HEC-6 model) within ArcView GIS environment. The extension was written in an Avenue script language and Dialog Designer with a series of 'point and click' options. The flood risk model was tested using the hydraulic and hydrological data from Pari River catchment area in Malaysia. The required sediment input parameters were obtained from field sampling. Sflood.avx has the capability of analyzing the computed water surface profiles generated from SFlood hydraulic model and producing a related flood risk map for Pari River in Arc- View GIS. The user-friendly menu Graphic User Interface guides the user to understand, visualize, build query, conduct repetitious and multiple analytical tasks with SFlood model outputs. The results of this study clearly show that GIS provides an effective environment for flood risk analysis and mapping. © 2005 Springer-Verlag Berlin Heidelberg.
