Features added in HydroCAD-8.0
Rainfall
Management: Displays rainfall depth or intensity in
graphical and tabular format. Displays multiple storms at once for easy
comparison. Works with all standard and custom
rainfall tables. Built-in rainfall editor makes it easy to create
custom rainfall definitions. Reports can be exported in TXT, CSV, EMF, or
JPG format for use in other programs.
Unit Hydrograph
Management: Displays, compares, and edits UH tables
with ease. Same features as rainfall management screen, above.
Chamber
Management: Displays data for prefabricated storage chambers in graphical or tabular format. Makes it easy to compare
different chambers, or create custom chamber definitions with the built-in
editor.
Pervious and
impervious runoff areas are reported separately. There is also
an option to perform separate runoff calculations for the pervious
and impervious areas, as required for some SBUH runoff calculations.
Curve Number
report provides a project-wide analysis of curve number usage, including the
total area for each CN value, making it easier to compare pre-existing and
proposed site conditions. See sample report.

Illustrated
reach cross-sections are shown on all reach reports and editing screens.
Maximum water level is shown in blue for quick evaluation of channel capacity
and utilization.
Custom reach
cross-sections allow the modeling of virtually any type of natural or
man-made channel, including compound channels and flood plains. A separate
Manning's value can be specified for each bottom segment, with a compound
roughness coefficient calculated by the Lotter, Pavlovskii, or Horton methods.
Flow can also be calculated by subdivision, based on the defined bottom segments
or break-points in the Manning's value.
Muskingum-Cunge
reach routing procedure has been added for enhanced modeling of long
channels with significant routing effects. Now a wide range of
projects that would otherwise have required TR-20 can be
done entirely within HydroCAD.
Custom project
units make it easy to adjust the number of decimal places for any parameter
- without having to create a custom units definition file.
Just click the "Custom" button on the units screen and select the parameter you
want to modify! And since the settings are stored within the individual
HydroCAD project file, you don't have to keep track of separate unit definition
files.
IDF Curve
Management: Displays, creates, and verifies IDF curves in
just seconds. Displays rainfall depth or intensity using linear or
logarithmic scaling. Other features similar to rainfall management, as
described
above.
Other
enhancements include selectable rounding for composite Tc, CN, and C values.
A link can be used to enter a constant flow, or to delay (translate) a
hydrograph by a preset time. New rainfall tables, unit hydrographs, and
chamber definitions have been added. As always, this update can open any previous HydroCAD project
file. Click here for technical details on
all the changes.
