Learn how to work with LiDAR elevation data to build accurate 3D terrain models in GeoHECRAS. This tutorial covers importing LAS/LAZ files, visualizing point clouds in 3D, generating terrain grids, managing units and resolution, adding online elevation data, and merging DEMs to fill data gaps and create a seamless elevation surface.

Learn how to get started with GeoHECRAS for hydraulic modeling. This tutorial covers HEC-RAS version compatibility and installation requirements, and demonstrates how to create and manage river geometry, cross sections, and terrain-based models. It also provides an overview of setting up a 1D hydraulic model and highlights key tools and workflows for efficient model development.
