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 in Texas; the tool differs from discrete-duration IDF in that it facilitates estimation for real-value durations (not discrete durations). $94,745.00. The tool differs from the earlier tool in appearance, and is password protected to reduce unintentional changes to the underlying database. The rainfall coefficients (E, B, and D) for the spreadsheet were created by interpreting the rainfall depth contours by duration and frequencies from research by the National Weather Service completed in the early 1960s and augmented in the 1970s.

In September 2018, the National Oceanic and Atmospheric The rainfall intensity is 7.6 in/hr. weighted based on the area of each respective land use and can be equal to the time of concentration. method. research will produce future e, b, d coefficients to better automate The peak flow is assumed to occur when the entire watershed is contributing runoff. This can be editied at will, but it worked quite well in this format. As Tc increases, total duration increases by 10 X. 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). These estimates are available through, Currently, the coefficients in Equation 4-21 can This load rating methodology is in accordance with the AASHTO Manual for Condition Evaluation of Bridges, 1993, and the AASHTO Standard Specifications for Highway Bridges, 14th Ed., 1989.
