This course is the first part of a comprehensive HEC-RAS learning path, focused on giving students a solid foundation in terrain-based hydraulic modeling. Designed for beginners, the course introduces the core components of HEC-RAS, a powerful free software developed by the U.S. Army Corps of Engineers for simulating water surface profiles in natural and constructed channels. #AulaGEOThroughout this course, students will move step-by-step from installing the software to creating their first steady flow model, using real terrain data and intuitive tools. Each section builds progressively, helping learners develop both practical skills and conceptual understanding.What You'll LearnHow to install and set up HEC-RAS on your computerHow to start a new project and navigate the HEC-RAS interfaceHow to generate RAS terrain models from various data sources, including USGS datasetsHow to modify the terrain and define essential river geometry elementsHow to lay out and edit cross sections for flow analysisHow to input steady flow data and simulate basic hydraulic conditionsHow to analyze results and refine your model for improved accuracyCourse StructureSection 1: Introduction and Software SetupGet familiar with HEC-RAS, install it correctly, and start your first project.Section 2: Creating and Importing RAS TerrainBuild accurate terrain models from multiple data sources for use in hydraulic simulations.Section 3: Terrain and Channel Geometry EditingDefine rivers and cross sections, modify terrain, and complete your geometric dataset.Section 4: Steady Flow ModelingSet up flow data, run steady flow simulations, and understand how water moves through your defined geometry.Section 5: Model Refinement and Result AnalysisMake adjustments to improve your model and interpret simulation outputs effectively.This course is part of the AulaGEO training series, focused on practical, hands-on learning for engineers, technicians, and GIS professionals. By the end of this course, you will be fully capable of building and simulating basic steady flow models in HEC-RAS - and ready for more advanced topics in the next part of the series.
