Implementation for Mapping Flood-Risk Areas – Case Study: The Municipality of Viana, Luanda Province (2024–2025).

Abstract

The proposal of a Geographic Information System (GIS) for flood mapping and mitigation relies on integrating and analyzing spatial data to identify vulnerable areas and aid preventive decisions. According to Longley, Goodchild, Maguire, and Rhind (2015), GIS is a tool that stores, manipulates, and represents geographic information, clarifying spatial relationships between environmental and human variables. In flood contexts, GIS analyzes relief, drainage, land use, and precipitation, producing thematic maps that indicate risk levels (Burrough & McDonnell, 1998). These maps guide land-use planning, infrastructure projects, and mitigation strategies, and help communicate risk to communities while supporting emergency plans (Smith, 2013). Overall, GIS enables more efficient, sustainable disaster management. and spatial monitoring.
