The Point Precipitation Frequency Estimates (available from https://hdsc.nws.noaa.gov/hdsc/pfds/) now have additional return intervals for 200, 500, and 1000. Any chance these will be added to the Table Lookup Storm events. Also the estimates given in the download table are slightly different...
Has anyone else experience a delay editing a Link? Delay is around 30 seconds, not a huge delay, but longer than other elements. The Links are not tied to any other projects. HydroCAD v 10.10-5a Five Node. Windows 10 Pro 64-bit, 32GB RAM, Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
I am trying to keep the slope on a reach based on a cross-section to lock. I enter the data for Inlet Invert, Slope, and then lock the slope, apply the changes. When I go back into edit the reach, the locks are open and the slope has changed. I have also tried locking both the Outlet Invert...
I have been working on a Texas Comission on Enviromental Qualtiy (TCEQ) Dam Breach Hydrologic & Hydrologic Analysis and had modeled the area above the dam as a single sub-basin as a catchment, the lake as a pond, and the dam spillway and breach as outlets of the pond. Peter Smart added the TCEQ...
I am working on a Dam Breach analysis for a small dam in Southlake TX. "The Hydrologic and Hydraulic Guidelines for Dams in Texas" by Texas Commission on Environmental Quality (TCEQ) states in section 8.4 Dam-Breach Models "For existing small or intermediate size dams, regardless of hazard...
The Texas Commission on Environmental Quality (TCEQ) Dam Safety Program document GI-364 "Hydrologic and Hydraulic Guidelines for Dams in Texas" 8.3 Breach Parameters / Breach Configuration (Embankments) requires a breach width minimum of 3 times the height of water being impounded and vertical...
I have a simple dam with a concrete weir 150 ft wide x 8 ft breath and 139 degree notch angle at the center of the dam. The rest of the earthen embankment starts at the top of the weir and increases asymmetrically to the top of the dam. Ideally I would like to know the flow associated with the...
I was able to download and add Type II 48-hr.hcr storm to the HydroCAD Rainfall Library. Is there a way to Use the 6-hr, 12-hr, 24-hr, and 48-hr to derive the 72-hr storm? We are getting into Dam projects that require looking at PMP/PMF events.
