EBDLKUP.xls is a spreadsheet tool in current use by the Texas Department of Transportation (TxDOT) engineers and other design engineers for estimating intensity-duration-frequency (IDF) of design rainfall by county; the tool differs from discrete-duration IDF in that it facilitates estimation for real-value durations (not discrete durations). The new tool was designed to maintain a similar interface and data structure to ensure that the revised coefficients can be inserted into existing design software (GeoPack-Drainage, WinStorm, and other drainage design tools that directly use the E, B, and D values). Structure geometry and analysis are based on the assumptions and limitations described in the help document. A variety of results reporting is provided, including exhaustive and comprehensive reports, reports tailored to specific design or analysis features, fabricator optional design evaluation reports, and a TxDOT Girder Schedule Report ("TxDOT CAD Output"). Typical Rainfall Intensity Duration Frequency -Storm duration lengthens in relation to Tc. Use of the rational method includes the following assumptions Where : I = design rainfall intensity (in./hr.) Use the calculated Existing Tc to determine the existing 10-yrand 100-yr Intensity. Precipitation at a point (perhaps measured by a rain gage) can be very intense and change rapidly over a short time, but high intensity cannot be sustained simultaneously over a large area. and should be used for all projects. These estimates are available through, Currently, the coefficients in Equation 4-21 can Location-specific IDF TxDOT Research Library - 0-6980 / Update Rainfall Coefficients with In so doing, the designer would use 5: Surface Test Type B for Concrete and Hot-Mix Asphalt Surfaces] from TxDOT's Maintenance Division to determine the proper pay schedule for the type of construction work to be done.

PDF City of Houston Design Manual Chapter 9 STORMWATER DESIGN REQUIREMENTS for various combinations of land use and soil/surface type. and limitations: The above assumptions and limitations are the reason the rational Depth duration frequency (DDF) and intensity duration frequency (IDF) of annual maximum rainfall throughout Texas needed to be updated from previous research and implementation projects sponsored by TxDOT (Asquith, 1998, and Asquith and Roussel, 2004). A NOAA analysis released today finds significantly higher rainfall frequency values in parts of Texas, redefining the amount of rainfall it takes to qualify as a 100-year or 1000-year event. Depth-Duration-Frequency coefficients for Texas were updated to 2015 DDF values. UT Bridge is a 3-dimensional finite element program for the analysis of curved steel I-girders and steel tub girders.
