Base question on HydroCAD runoff Volume question
Base question on HydroCAD runoff Volume question
(OP)
Hi guy:
I got a question regard HydroCAD report. In the report, there are always got two lines list out the summary of the model out come such as total run are, and precent of the previous or Impervious and are, etc. Is the reach in the model affect the 'Runoff volume'. I think there is a separate calcution to do those calculation.
thank you

The final discharge volume from your site will be the sum of all the runoff, unless you retain or infiltrate some of the volume.
Peak flow reduction is another matter. This is easily achieved by detention.
Which of these are you asking about? Please be clear about your terminology.

FYI, all HydroCAD reports will have a standard HydroCAD page heading, including the software version, serial number, copyright, date prepared, etc.

Pond 6P is labeled "Stone infiltration", and has an inflow that matches the runoff. It appears that all the runoff is being infiltrated, producing zero discharge from the pond. This zero flow is presumably routed to Reach 5R which is labeled "Total Runoff".
To be sure of this, you really need to examine the routing diagram, and not just the node summary you provided. If in doubt, ask the person who prepared the report. This is a matter of how they chose to model the site, rather than a HydroCAD question per se.
