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). Since joining the Double R team in 2011, Paul Jamali has learned what it means to wear many hats. area, runoff coefficient, and mean rainfall intensity for a duration Peak flow is assumed to occur when the entire watershed is contributing to flow. Depth-Duration-Frequency coefficients for Texas were updated to 2015 DDF values. 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"). This download also contains the Center to Center Test Suite application, used to validate the plugin against the defined interface, and the Status Logger application needed for the Test Suite application.
