Flood Risk Assessment using Grass GIS

Introduction

With global climate change becoming the prevalent issue of the generation, more and more people are using GIS to emulate the effects of climate change in their communities. Rising water levels are especially of concern as humans tend to settle near water bodies and coastal areas. This tutorial aims to give an introductory lesson into conducting a very basic flood risk assessment using open source software and data. This tutorial utilizes Grass GIS and data from the city of Daytona Beach, FL, USA, a popular vacation destination on the Atlantic Coast.
