Extracting Water Surface Elevation for Levee Profile Lines
This article shows how to fix the "Weir Submergence Not Set" error.
RASter Calculator scripting for RAS Mapper
This article explains how to perform RASter Calculator scripting in RAS Mapper. Scripting in RAS Mapper is useful for analyzing RAS raster results.
HEC-RAS 6.0 Project Example Opening Errors – Solved!
This article addresses a common error that occurs when trying to open the 2D Unsteady Flow Hydraulics example projects in HEC-RAS 6.0.
PowerPoint Screen Record
Screen recordings are a powerful tool to help display and share animations from your RAS model. You can create screen recordings of the RAS Mapper animations that can be used to show changes in velocity, WSE, Depth, or any other mapping variables over time, instead of as a still image. There is software out there […]
1D/2D Offline Connection Issues
Written by Chris Goodell | Kleinschmidt Associates Copyright © The RAS Solution. All rights reserved. I’ve mentioned this before, but I am thoroughly impressed with the robustness of the finite volume solution scheme used in 2D areas in HEC-RAS. As long as your Courant Numbers are in a good spot, you rarely get errors and instabilities in […]
Georeferencing hard copy or pdf maps
Using RAS Mapper as a GIS tool Part 3: Georeferencing hard copy or pdf maps Have you ever received your background data in hard copy or pdf format and wanted to view it in its georeferenced location? For this final topic in our three-part series on using RAS Mapper as a GIS tool, we’ll cover […]
Shifting web imagery with world files for HEC-RAS
Using RAS Mapper as a GIS tool Part 2: Shifting Web Imagery with World Files Have you ever tried pulling web imagery into RAS Mapper only to find that it doesn’t line up with your existing shape files, terrain surfaces, or other geospatial data? In this second of a three-part series on using RAS Mapper […]
Removing bridge decks from terrain surfaces
Using RAS Mapper as a GIS Tool Part 1: Removing Bridge Decks from Terrain Surfaces This is the first in a three-part series on using RAS Mapper as a GIS tool. In this post we’ll cover the removal of bridge decks from terrain data. This topic comes up fairly frequently, since LiDAR data may be […]
HEC-RAS Primer for New Users
Are you a new HEC-RAS user? Or maybe you’ve used HEC-RAS before, but it’s been a while. Maybe you have no idea where to start. Steady or Unsteady? 1D or 2D? Subcritical or Supercritical? OK, for all you Newbies out there, I’m going to walk you through some steps to take to get you up […]
Creating Static Results Maps (Shapefiles or Rasters) using RAS Mapper
Many readers have been asking how to create shapefiles and other static maps in RAS Mapper. One of the main differences between RAS Mapper in RAS 4.1 and RAS 5.0 is the existence of Dynamic Maps. What makes these maps dynamic is that when you have that Results Layer selected in RAS Mapper, you can […]
Getting Profile Output in a 2D Area
Back in September 2015, I wrote an article on how to extractflow data from a transect in a 2D area. This was a round-about way of getting flow flux data out of RAS Mapper. Back then the beta version of HEC-RAS 5.0 was somewhat limited in the ways data could be extracted from a 2D […]
Post-Processing: Creating Inundation Maps with very Large Terrain
We often have to deal with very large models covering hundreds of river miles. The terrain data associated with these models can be equally massive, which can cause memory/processor issues when trying to delineate inundation maps. This post is not concerned with pre-processing our model geometry. Instead, we have a completed model with results we […]
