Mud and Debris Flow Modeling with HEC-RAS (Part 2 - Non-Newtonian Hydraulics)

[@TheBalticSun]

thanks for sharing with us Dr Gibson. I have a question: I have carried out models with Bingham parameters where I have only varied the Cv, and I have obtained different results. However, Bingham equation doesn't depend of Cv, so similar results should be obtained. How does Cv influence the Bingham formula?

Did you use the exponential equations for yield and viscosity or bulking? Those depend on Cv.

@@HEC-RAS no, I didn't, I used yield strength and defined viscosity values and do not bulking. If I select defined yield strength and viscosity values (the same way you do at the end of the video), how is Cv related to fluid characteristics without using the exponential method?
Thank you for answering, greetings from Chile!

Hi , thanks for great video! I'm Trying to run Non-Newtonian analyses. getting following error ?

How do I solve this ?
