    How to Model a Filtration Bioretention System

    Thanks! Was speaking with a colleague and he suggested the same, which at least fixes the error code. However, it still doesn't model correctly as a single node filter practice in Hydrocad. It looks like hydrocad fills a basin from the bottom up, regardless of the elevation of the inlet pipe...

    How to Model a Filtration Bioretention System

    I'm trying to figure out how to model this type of practice so I can understand how the Stage Voids. I have the pond setup as follows, so that the lower four feet is the 40% porosity soil and the upper 1.5 feet is open water. In the outlets I have an orifice/grate at 523.5 and the culvert...

    Hazen-Williams Equation entry and units

    I am building a worksheet that calculates head loss due to friction in water pipes. I am using the Hazen-Williams equation. The commonly used version of this equation uses mixed units (e.g. ft, inches, gpm), and has several standard coefficients that end up giving the result in feet. When I...

    Review and suggestion needed about my HEC-RAS model

    Hi philosophy- I think what RWF7437 is trying to say is that calculating a flow of 1134 and assuming that is "accurate" is incorrect, as neither the calculation methods or the field measurement methods are that accurate. I don't think that entering that exact SCS value into HEC-RAS is wrong...

    Modeling Open Channels in Hydraflow

    HEC-RAS. I can't believe I didn't think of that- I've only been using it for 6 years. Thanks for your help. I know that Hydraflow is not longer available as a standalone. Since their website is gone, I don't have access to their user forums anymore. The design flows have to be generated...

    Modeling Open Channels in Hydraflow

    Using the standalone versions of Hydraflow Express, Stormsewers, Hydrogragphs. Also had easy access to the Civil 3D extensions, but haven't used them yet. Trapezoidal channel, and the cross-section stays the same for the length of the channel. Due to site restrictions, the alignment cannot be...
