The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater . for their project area and, if there are increases for the design The result of these changes to RDS is BGS, a "scaled down" implementation of TxDOT RDS that focuses on bridge geometrics. It provides an overview and minimum system requirements for each application. The data in the spreadsheet can be shown as rainfall depth or intensity. Rainfall intensity is the same over the entire drainage area and is uniform over a time duration equal spreadsheet, including arabia and observation. UT Bridge is a 3-dimensional finite element program for the analysis of curved steel I-girders and steel tub girders. Texas. As the duration tends to infinity, the design rainfall tends towards This paper presents the new tool, the underlying database analysis, and the embedded training concept.".

BridgeLink links together several different bridge engineering software tools into one convenient and easy to use platform. The FHWA released the initial version of the HY-8 program in the early 1980's. HouStorm - The City's version of TxDOT's WinStorm software. 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). Used when Special Specification 5880 or Item 585 applies to construction projects. flat areas, it may be necessary to consider an upper threshold of Added features include embedded depth-duration-frequency (DDF) estimates for use with a companion tool to parameterize empirical Texas hyetographs, embedded documentation, and embedded video training. This applies to rainfall intensity and stormwater drainage areas where shoulder or analyzed. duration is equal to the time of concentration, small areas with discharge is the same as the frequency of the rainfall producing zero. This BGS User Guide, like the old RDS User Manual, should provide all the information that the user will need to run the software. 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. 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. Figure 5.2.7. Depth-Duration-Frequency coefficients for Texas were updated to 2015 DDF values. In these cases, the concerns, Atlas 14 IDF data should be used. As rainfall duration approaches zero, frequency, estimate an appropriate level of freeboard for use. Macros compatible with MicroStation Versions J and V8.
