Physical Characteristics of Ponds
There are categories of storage elements that can be modeled in Bentley SewerGEMS CONNECT:
- Outdoor ponds with a free surface
- Large underground pipes built solely to store water during storms
- Wet wells at pumping stations
The first two are modeled as ponds in Bentley SewerGEMS CONNECT. Any of these elements may be used as the suction side of a pump.
The following pond volume options are available:
Not all of the physical properties are needed for each method of describing pond (storage element) dimensions.
The type of attribute needed for each type of data entry is summarized in the table below:
