2 Introduction Backgraound P41995 Mohamad Abdul Rahman According to the World Meteorological Organization (WMO), from research conducted in several countries show that the forecasting and warning about the dangers of flooding can reduce the potential loss of 6% to 40% Early exposure to the local community with respect to the types of flooding, flood situations, the benefits can be obtained and how prevention is important so that they can be read (Grelot & Guillaume 2003) SPBB Tool ArcGIS 9.3 ® SPBB 2 GOVERNANCE & DISASTER MANAGEMENT GOVERNANCE & DISASTER MANAGEMENT

3 Introduction Backgraound P41995 Mohamad Abdul Rahman Most flood reports only focused on the water level rise, rather than the size of the overflow. Both are essential information disseminated to the local community as early preparation for the flood SPBB Tool ArcGIS 9.3 ® SPBB 3 Problems…..
