Group-based Decision Support for Flood Hazard Forecasting: A Geospatial Technology-based Group Analytic Hierarchy Process Approach

A Geospatial Technology-based Group Analytic Hierarchy Process (GAHP) is carried out to forecast the likely flooded areas based on a total number of five set of criteria/factors believed to be influencing flood generation in the study area. The GAHP is based on the two categories of experts (hydrolo...
