You will learn to use RAS Mapper to import and modify terrain data, create landuse layers for roughness, and set up 2D geometry, cell size, and spacing to best represent terrain and flow. The course covers connecting 1D and 2D areas, representing river channels, entering boundary conditions, running scenarios, and adjusting computation options and intervals. You will learn to view and analyze both 1D and 2D results, gaining practical skills for advancing from 1D to 2D hydraulic modelling in geo-referenced environments. All required data is provided, and HEC-RAS is free to download. This course is suitable for those studying river processes in academia or working in river engineering.<\/p>\n<h3>What you\u2019ll learn<\/h3>\n<ul>\n<li>Work with RAS Mapper in HEC-RAS to create terrain layers for 1D and 2D river modelling.<\/li>\n<li>Import 1D cross-section data to build accurate river channels.<\/li>\n<li>Create landcover layers and apply Manning\u2019s n values.<\/li>\n<li>Create 2D meshes, set cell parameters, and add refinement regions and breaklines.<\/li>\n<li>Build lateral structures to connect 1D and 2D elements.<\/li>\n<li>Adjust 2D areas to create optimal river channel meshes.<\/li>\n<li>Enter unsteady flow boundary condition and initial condition data.<\/li>\n<li>Set up unsteady runs and configure computation options and tolerances.<\/li>\n<li>Choose appropriate time-steps using the Courant Number.<\/li>\n<li>View and interpret 1D and 2D results.<\/li>\n<\/ul>\n<h3>Who this course is for<\/h3>\n<ul>\n<li>Anyone interested in advancing hydraulic modelling skills from 1D to 2D using RAS Mapper in HEC-RAS.<\/li>\n<\/ul>\n<h3>Specificatoin of A Practical Introduction to 2D River Modelling in HEC-RAS<\/h3>\n<ul>\n<li>Publisher : <a href=\"https:\/\/href.li\/?https:\/\/www.udemy.com\/course\/a-practical-introduction-to-2d-river-modelling-in-hec-ras\/?couponCode=MT251002G4\" target=\"_blank\" rel=\"noopener\">Udemy<\/a><\/li>\n<li>Teacher : <a href=\"https:\/\/downloadlynet.ir\/tag\/nick-wallerstein\">Nick Wallerstein<\/a><\/li>\n<li>Language : English<\/li>\n<li>Level : Intermediate<\/li>\n<li>Number of Course : 57<\/li>\n<li>Duration : 8 hours and 19 minutes<\/li>\n<\/ul>\n<h3>Content of A Practical Introduction to 2D River Modelling in HEC-RAS<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1010964\" src=\"https:\/\/downloadly.ir\/wp-content\/uploads\/2025\/10\/A-Practical-Introduction-to-2D-River-Modelling-in-HEC-RAS.c.jpeg\" alt=\"A Practical Introduction to 2D River Modelling in HEC-RAS\" width=\"705\" height=\"697\"><\/p>\n<h3>Requirements<\/h3>\n<ul dir=\"ltr\">\n<li>A basic understanding of the concepts involved in river hydraulic modelling would be beneficial but the course learning goals can be achieved without the need for any prior experience of using HEC-RAS.<\/li>\n<\/ul>\n<h3>Pictures<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1010965\" src=\"https:\/\/downloadly.ir\/wp-content\/uploads\/2025\/10\/A-Practical-Introduction-to-2D-River-Modelling-in-HEC-RAS.d.jpeg\" alt=\"A Practical Introduction to 2D River Modelling in HEC-RAS\" width=\"705\" height=\"286\"><\/p>\n<h3>Sample Clip<\/h3>\n<div style=\"width: 640px;\" class=\"wp-video\"><span class=\"mejs-offscreen\">Video Player<\/span><\/p>\n<div id=\"mep_0\" class=\"mejs-container mejs-container-keyboard-inactive wp-video-shortcode mejs-video\" tabindex=\"0\" role=\"application\" aria-label=\"Video Player\" style=\"width: 640px;
