Welcome to the RAS Solution

You’ve arrived at The RAS Solution. The best help site for all things HEC-RAS. I do receive a lot of questions in the post comments. I try to respond to all questions, but sometimes it gets a little busy. Please be understanding. Whether you are new to HEC-RAS or a seasoned expert, I think you’ll find a lot of great stuff in here. Check out the HEC-RAS Vodcast (video podcast) I do with Ben Cary called Full Momentum

The Author

Chris Goodell, Principal Consultant for H&H at Kleinschmidt Associates, is a former HEC-RAS Development Team member and teaches HEC-RAS courses around the world. He is the author of the popular book "Breaking the HEC-RAS Code."

"BREAKING THE HEC-RAS CODE"

This book covers one of the most powerful, yet relatively unknown features available in HEC-RAS: 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, and plotting output.
