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"). exceedingly short times of concentration could result in design units. The TxDOT Bridge Geometry System (BGS) is useful for bridge geometric design. The rainfall intensity is assumed to be uniform over a time duration equal to or greater than the time of concentration, T c. The peak flow recurrence interval is assumed to be equal to the rainfall intensity recurrence interval. rainfall based on the new NOAA Atlas 14 rainfall data from the older Type I-III distributions commonly used in Texas today. than 20% of drainage area has good cover, Fair to good; about 50% of area in good grassland or woodland, 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).
