Flood Risk Modeling in ArcGIS Pro | Terrain Analysis for Watershed & Flood Risk

In this video, we walk through a terrain analysis workflow in ArcGIS Pro to model potential flood risk in the Salt Lake Valley if the Red Butte Reservoir dam were to fail. This hands-on tutorial covers key hydrology and spatial analysis tools that are commonly used in watershed and flood hazard studies. You’ll learn step by step how to: Use the Fill tool to prepare elevation data by removing sinks. Generate Flow Direction and Flow Accumulation rasters. Delineate a stream network with a threshold and apply Stream Order. Convert stream rasters to vector features using Stream to Feature, and isolate Red Butte Creek. Create a cost surface by integrating Aspect, Euclidean Direction, and Raster Calculator operations. Model flood risk using the Path Distance tool with cost and elevation rasters. Delineate the watershed boundary with the Watershed tool and refine outputs with Extract by Mask. Produce a final map layout showing Red Butte Creek and the modeled flood hazard. This exercise demonstrates how GIS can be applied to simulate flood risk assessment, a crucial step in water resource management, urban planning, and hazard mitigation. Whether you are a student, researcher, or GIS professional, this tutorial provides a clear example of integrating hydrology and cost-distance tools in ArcGIS Pro.
