Overview

The Pond Modeling and Design Process:

1.     Model Pre- and Post-Development Flows

2.     Calculate Required Storage

3.     Prepare the Pond and Pond Structures

a.     an Outfall structure into the pond

b.     a Pond Outfall Structure

c.      a Pond Feature (a shape designated to “hold” the hydraulic requirements of a pond (storage characteristics, etc.)

d.     a Pipe between the Pond Outfall Structure and the Site Endwall.

4.     Adjust Catchment Outflows if necessary

a.     If Catchments were routed to a structure that gets pre-empted by a pond:

                                                    i.     Move the Proposed Catchment outflows from the Site Outfall to the Pond Outfall

5.     Connect the Pond Feature to the Network

6.     Define the Pond Outlet Control Structure(s)

7.     Evaluate and Refine

a.     Compute the Scenario

b.     Analyze

c.      Adjust as necessary

CivilStorm License

Time-varying calculations require an elevated license (CivilStorm or above).  This license may or may not be available and may invoke an additional fee from Bentley. Check with your CAD Administrator.

1. To activate CivilStorm, click Drainage and Utilities > Tools > License Activation > CivilStorm

Much of the required work can be done with the default StormCAD license, the CivilStorm license is necessary for Computations, Time-varying analysis and some graph functions.
