In an earlier blog post, we discussed some details regarding modeling overflow gates in HEC-RAS. These gates are typically used in irrigation canals. This blog post generated many interesting questions and comments regarding modeling irrigation canals in general using HEC-RAS. Thus, we felt it might be interesting to address some of these questions in a […]
The new and improved RAS Mapper interface in HEC-RAS 5.0 makes managing and exporting model results like an inundation extents shapefile or a depth grid for use outside of HEC-RAS/RAS Mapper easy. The process (which is described in detail in Chapter 5 of the HEC-RAS 5.0 2D Modeling User’s Manual) requires the user to add […]
Well it’s been one year since I published “Breaking the HEC-RAS Code”. It was a lot of work, but I am very pleased to see how many people are making use of the book controlling and automating HEC-RAS with their own codes. For those of you who haven’t discovered it yet, this book introduces […]
There has been a lot of demand from new owners of the book “Breaking the HEC-RAS Code” for example code in VBA form. So…here it is! Aside from the obvious fact that you wont have to re-type code from the book into your own Excel VBA modules, this Excel Workbook provides the benefit of seeing […]

As you do more and more programming with the HECRASController, please consider sharing some of your useful code with others. […]
One of the most powerful, yet relatively unknown features available in HEC-RAS is the HECRASController. The HECRASController API has a wealth of procedures which allow a programmer to manipulate HEC-RAS externally by setting input data, retrieving input or output data, and performing common functions such as opening and closing HEC-RAS, changing plans, running HEC-RAS, […]
Are you an HEC-RAS user? Yes? OK, try this out: 1. If you haven’t already done so, install the HEC-RAS example projects to the default location. 2. Open up a blank workbook in Excel. 3. Press Alt-F11. When the Visual Basic Editor Window opens up, select Tools…References… 4. Scroll down until you see HEC River […]
