WebDec 8, 2008 · This could be from improperly defined ineffective flow triggers, bad htab parameters, or poor definition of flow conveyance (i.e. n value break points). It’s also very common to see profiles intersect just upstream or through a bridge/culvert. Usually this is due to a flow regime switch (low flow, to pressure flow to pressure/weir flow). WebJan 16, 2024 · Regarding this, we are having a bug issue (with 5.0.4 at this point) where our Htab curves do not update based on the Htab parameters entered. In our case, it is at a culvert crossing (similar to bridges) but does not update in the same manner. Note: the GUI for the culvert has a button "Get parameters from Htab…" rather than a "refresh" button.

WebAug 3, 2009 · This needs to be modeled with ineffective flow areas. However, since it is an unsteady flow model, check the Htab parameters for your culvert first (its easy to do). Try to refine the parameters as much as possible. I'll usually try 80/60/40 for my number of points/curves. Also, provide a max elevation and max flow. WebNov 11, 2024 · Rather than re-computing the hydraulic parameters at every time step, RAS can simply pick the value off the chart. These curves (actually the paired data that creates them) are used by HEC-RAS during the unsteady flow computations. The figure below shows the conveyance HTab curve for a cross section.

WebOct 8, 2013 · Notice now in the HTAB parameters property table, the HTAB definition begins at the elevation of the invert of the side channel that was previously defined as the main channel.
