The configure option is where the routing actually happens. This screen allows you to select the treatment to use for all the catchments and allows you to route them to an outlet.
Spreadsheet Blocks
From: This is the catchment number that will be routed.
To: You can route to another catchment (BMP) or to the outlet (We use Catchment 0 to indicate the outlet)
BMP Used: You can use any of the defined treatments as the BMP for a catchment.
Edit: Edit lets you define the BMP to use for the (upstream) catchment in routing. It will take you to the Routing screen.
Adding Catchments to Routing
The Add Catchment button will allow you to add a Catchment to a routing. You can define catchments that you do not use in routing. This allows you to easily compare options by changing the catchments used in a routing.
Special Cases
BMPFast handles a number of special calculation cases. These include Retention in Series and Detention in Series.
Reports
Flow Balance
Full Routing
Retention (only available for Retention in Series)
Detention (only available for Detention in Series)
Limitations
BMPFast has been tested for catchments in series. You can have multiple series of catchments routing to an outlet. A series of catchments that route to other series of catchments have not been tested, and results may not be accurate. 2 series of catchments routing to a single catchment have not been tested, and results may not be accurate.
These specific scenarios are allowed in the program, and plans are underway to test the different possible routing scenarios for accuracy.
