1D Dam Break Modelling using HEC-RAS | Without Storage Reservoir | Hydrology Hub

1D Dam Break Modelling using HEC-RAS (Without Storage Reservoir) | Step-by-Step Tutorial | Hydrology Hub Welcome to Hydrology Hub! In this lecture, you will learn how to perform One-Dimensional (1D) Dam Break Modelling in HEC-RAS without explicitly defining a storage reservoir. This approach is particularly useful for understanding the fundamentals of dam break analysis and simulating breach outflows in river systems where the reservoir is represented through upstream boundary conditions. This step-by-step tutorial covers the complete workflow, from geometry creation to result interpretation, making it suitable for beginners as well as practicing engineers. 📚 Topics Covered ✔ Introduction to 1D Dam Break Analysis ✔ Creating River Geometry and Cross Sections ✔ Defining Dam Location in HEC-RAS ✔ Breach Parameters and Failure Scenarios ✔ Setting Up Unsteady Flow Data ✔ Boundary Conditions and Simulation Settings ✔ Running Dam Break Simulations ✔ Troubleshooting Common Errors ✔ Analysis of Water Surface Profiles ✔ Flood Hydrographs and Peak Discharge Attenuation ✔ Interpretation of Dam Break Results 🎯 Applications of 1D Dam Break Modelling Dam Safety Assessment Emergency Action Plan (EAP) Preparation Flood Risk Assessment Downstream Impact Analysis Preliminary Dam Break Studies Reservoir and River Management Disaster Preparedness and Mitigation 👨‍🎓 Who Should Watch? Water Resources Engineers Civil Engineering Students Dam Safety Professionals Researchers and Academicians Disaster Management Officials Consultants working on Flood and Dam Break Studies This lecture will help you understand the core concepts of dam breach modelling and prepare you for more advanced 2D dam break simulations in HEC-RAS. 🔔 Subscribe to Hydrology Hub for tutorials on: HEC-RAS 1D & 2D Modelling Dam Break Analysis HEC-HMS Modelling Flood Forecasting Flood Hazard Mapping GIS and Remote Sensing Applications Hydrology and Water Resources Engineering 👍 Like | Share | Subscribe | Comment your questions below
