Stream & Drainage Network Analysis in ArcGIS 2025 Using DEM | Step-by-Step Tutorial

Unlock the power of ArcGIS 2025 with this step-by-step tutorial on how to perform Stream and Drainage Network Analysis using DEM (Digital Elevation Model).

In this video, you’ll learn how to extract, visualize, and analyze stream networks and drainage patterns directly from DEM data using ArcGIS Hydrology tools. Perfect for GIS analysts, hydrologists, environmental scientists, and geology students, this guide takes you from raw elevation data to a complete drainage network map ready for analysis and presentation.

💡 What You’ll Learn:

✅ How to prepare and preprocess DEM data
✅ How to use the Flow Direction and Flow Accumulation tools
✅ Steps to extract stream networks and drainage basins
✅ How to create and symbolize a drainage density map
✅ Tips for improving visualization and analysis accuracy

Whether you’re studying hydrological modeling, flood analysis, or watershed delineation, this tutorial will help you build professional-quality results using ArcGIS 2025.
