Welcome to the Texas Department of Transportation FTP Server Regression equations are recommended as the primary hydrologic method for off-system (non-TxDOT) projects; for on-system projects, they are recommended as a check on other methods. This real-value duration capability is a great utility tool for many hydrologic methods such as the rational method. The Tc is put into the TxDOT spreadsheet for calculating Rainfall Intensity-Duration-Frequency Coefficients for Texas Counties. Rainfall intensity was calculated using the following equation from the City of Houston Design Manual. Custom defined beam shapes that fit within each family of girder types supported by PGSuper can also be added to the user copy of the templates, thereby extending the girder shapes that the user can design, analyze, and load rate with the program.

Precipitation Frequency Data Server (PFDS) website and the 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). A companion tool named TXHYETO-2015.xlsx was built to enable designers to rapidly generate Texas specific hyetographs for importing into HEC-HMS and similar hydrologic modeling software using an approximation to the tabulations reported in Williams-Sether and others (2004). the designer with a peak discharge value, but does not provide a 1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS) .
