• Abstract:
  The FHWA Hydraulic Toolbox Program is a stand-alone suite of calculators that performs routine hydrologic and hydraulic analysis and design computations. Specific calculators address: Rational Method hydrology, channels, channel linings, weirs, curb and gutter sections, storm drain inlets, detention basins, bridge scour, riprap countermeasures, sediment gradations, and culvert assessments. The Hydraulic Toolbox significantly extends the basic functionality of the historic version of the FHWA Visual Urban Program and other tools. The program allows a user to perform and save hydraulic calculations in one project file, analyze multiple scenarios, and create plots and reports of these analyses. The computations can be carried out in either US Customary Units or the International System of Units.
  
  Improvements made to this version of the software include the following: Updated user guide documentation. Enhanced 508 compliance. The program can now be navigated with the keyboard with increased menu tools and navigation. Each dialog was reviewed for keyboard navigation. The documentation has been updated to follow 508 compliance by using formatting, style sets, and alternate text for images. The report generator was updated to use style sets. Upgraded interface for high pixel density displays and interface icons. Added option to display rock riprap gradations in inches, feet, or millimeters. Added option to set default unit system and profile. Upgraded to a new library to export data to the report generator with Microsoft Word format (DOCX). Channel Calculator: Fixed issue with unit conversion using cross sections. Removed lining calculations from the Channel Calculator since these calculations are in the Channel Lining Calculator. Channel Lining Calculator: Modified the note in rolled erosion control product (RECP) field for ½ inch of erosion. Fixed issue where Da/D50 leaves the range of computation resulting in a message "Root must be bracketed in Newton Raphson". Weir Calculator: Fixed issue with SI units reducing head or flow with each computation Added "irregular weir" computations. Rational Calculator: Removed NOAA Atlas 2 data from states where NOAA Atlas 2 is available. Added NOAA Atlas 14 online data to the Intensity-Duration-Frequency data. Fixed issues with computing a rational hydrograph with small times of concentration. Detention Basin Calculator: Fixed issue with unit conversion. Riprap Calculator: Fixed issue with transferring data from the channel calculations. Bridge Scour Calculator: Fixed plotting large number of piers and subsequent overlapping scour holes. Fixed logic determining Abutment Type A or Abutment Type B. Altered gradation note to be consistent with HEC-18. Removed incorrect note about Meyer-Peter and Muller method. Created channel width note for removing pier widths to indicate that the pier widths have been removed when exported by SMS. Added 2 significant figures for Energy Grade Line Slope. Fixed issue with abutment scour elevation. Fixed issue with length of embankment visibility. Added option to specify clear-water or live-bed contraction scour in the NCHRP abutment scour computations. Added note in pier scour "if L/a > 12, use 12". Fixed issue with no computed answer. Fixed issue with negative scour depths being used in the scour summary table. Fixed issue with pressure scour with multiple scenarios not being correctly added to the scour summary table. Fixed issue with computing an eroded cross section with a NCHRP abutment in Scour Condition A. Changed the default abutment type to be spill through. Fixed unit conversion issue when importing a HEC-RAS file. Added a new variable in pressure flow: "Depth at upstream bridge face". Fixed error in note for cohesive soil limit (fixed from noncohesive soil limit). Fixed issue with showing correct computed values in the scour summary table. Modified report generator to export all scenarios instead of only the selected scenario.
