🌍 How to Create a Flood Risk Assessment Map in ArcGIS (Weighted Sum Overlay Method)

Flooding is one of the most pressing urban challenges today. As planners, GIS analysts, and researchers, we need actionable tools to identify high-risk zones and guide resilient development.

In this tutorial, I walk you through building a Flood Susceptibility Map in ArcGIS using the Weighted Sum Overlay method. Step by step, we synthesize 7 critical layers; Slope, Elevation, Rainfall, Land Use/Land Cover, Drainage Density, and Distance to Rivers/Roads, into a professional risk assessment map.

What you will learn:
* How to prepare and reclassify raster data
* Assigning weights and ranking variables
* Using the Spatial Analyst Overlay tools effectively
* Designing and analyzing the final flood risk output

If you are working on urban resilience, climate adaptation, or GIS-based planning, this guide will help you create maps that inform real-world decisions.
