Fundamentals of Flood Modeling with the 1D HEC-RAS Model

Floods are among the most frequent and destructive natural hazards worldwide. Understanding how water flows in rivers—and how floods can be simulated, predicted, and mapped—is essential for engineers, hydrologists, GIS analysts, researchers, and disaster management professionals.

This course provides a complete, step-by-step introduction to flood modeling using the industry-standard software HEC-RAS (1D). Designed for learners at all levels, the course focuses on practical, real-world applications, enabling you to build job-ready skills that are directly used in engineering firms, government agencies, and research organizations.

You will learn everything from the basics of flood hydrology to creating and running your own 1D HEC-RAS flood simulation, including geometry creation, cross-section development, steady/unsteady flow simulation, and flood mapping. The course ensures that even complete beginners can confidently build and analyze a flood model.

This is a fully job-oriented course with hands-on demonstrations, simple explanations, and real project workflows. By the end of the course, you will be able to apply 1D HEC-RAS modeling techniques to academic projects, consultancy assignments, and professional flood studies.
