Galileo and Missoula Flood Modeling
I’m honored to have worked with Galileo on this article. It’s a great read and demonstrates the benefits of adding Galileo to your HEC-RAS modeling tool box. Click here for the full article. https://galileoapp.io/hec-ras-galileo-wine-have-in-common/
Very fine 2D Modeling
I’m a big fan of testing HEC-RAS to the limits. What can it do? What can’t it do? These are questions we should all ask at the beginning of a project. Can HEC-RAS actually prove to be a useful tool in answering hydraulic-related questions for our specific problem? Shortly after coming to work at Kleinschmidt […]
HEC-RAS in Three Dimensions
Now this is the kind of post that gets you on The RAS Solution! Cutting edge creative solutions to complex problems. This is great stuff. Thanks Michael for all the effort you put in to this. In today’s post we’ll cover two methodologies that leverage HEC RAS results to create impressionable and multi-dimensional flood visualizations. […]
2D HEC-RAS Class in Boise October 28-30
HEC-RAS Modelers! Don’t miss this opportunity for 2D HEC-RAS training in beautiful Boise Idaho. I’ll be teaching this class and hope to see you there! There are limited seats for this class so don’t delay in signing up. This will be a three-day course with a mix of lectures and workshop exercises. You will learn […]
Those Nuisance Cell Errors and Wedge Depressions
If you’ve been doing some 2D modeling, you most likely have run into what I call nuisance cell errors. You see them while your model is running and they can really slow down your simulation as the RAS chugs through iterations to try to come to a solution. The errors here are in the […]
Preview of the new Finite-Volume Approach for 1D Reaches
One of the most anticipated new features soon to come in the next major version of HEC-RAS (Version 5.1) is the option of running unsteady 1D reaches with a finite volume solution scheme. This will be a fantastic addition to HEC-RAS. Gary Brunner recently gave me a brief overview of the new finite volume feature […]
Using a HEC-RAS Storage Area and Lateral Structures to Replace Standard Reach Junctions
Situation: Advances in HEC-RAS now allow for improved simulation of overbanks using 2D Flow Areas. Coupled 1D/2D models where 1D cross-sections represent the bank-to-bank cross-section data and 2D flow areas represent overbank areas has greatly improved the accuracy and robustness of HEC-RAS models. This is particularly the case in flat, urban areas with significant overbank […]
HEC-RAS 2D and Sediment Dynamics Course in Portland Oregon
Please join me this October for a fantastic opportunity to learn 2D HEC-RAS and Sediment Dynamics. Both courses are open to all and will be hosted by River Restoration Northwest and Portland State University. Take one or both courses! This was very popular last year and sold out so don’t wait too long to register. […]
Participate in the Development of HEC-RAS-Spatial Precipitation and Infiltration
Here’s an opportunity to have a direct impact on the development of spatial precipitation and infiltration methods in HEC-RAS. Please read the message from Gary Brunner, Lead Developer of HEC-RAS, and if you would like to provide feedback to his questions, please do so in the comments section at the bottom of this post. If […]
HEC-RAS 5.0.5 has been released!
HEC has released a new version of HEC-RAS called version 5.0.5 today. This version is a bug fix only version (i.e. No new features). Unfortunately in version 5.0.4 there was a bug in which User defined Manning’s n value override regions for 2D Flow Areas (called “2D Area Manning’s n Regions”), define in the Geometry […]
