HydroCAD® Stormwater Modeling - Since 1986
HydroCAD Supports ecoChamber
HydroCAD provides direct support for ecoChamber stormwater chambers manufactured by ecoChamber LLC of Bowling Green, Ohio. This allows the ecoChamber to be easily used within any HydroCAD model for stormwater storage, detention, or infiltration.
How chambers are modeled
In a HydroCAD model, stormwater chambers typically appear as part of the storage definition for a "pond". In the simplest case, HydroCAD calculates the available storage for use with other calculations. But more often, it is used to generate a complete inflow or runoff hydrograph and route it through the pond. The resulting analysis indicates the water levels attained throughout the rainfall event, as well as any discharge that may occur through outlet devices or infiltration into the surrounding ground.
Flexible storage options
Each pond may include an unlimited number of storage definitions as required to describe its overall storage characteristics. This makes it easy to model complex storage arrangements, such as a combination of multiple chambers, pipe storage, catch basins, or other contributing volumes, such as above-ground areas (parking lots) that may provide overflow storage for certain events.
But the most significant feature is the ability to embed (bury) chambers in a bed of crushed stone, and have HydroCAD automatically calculate the combined storage at any water surface elevation. This makes it easy to determine the storage for virtually any configuration of storage chambers, without resorting to any manual calculations.
Modeling the ecoChamber in HydroCAD
Setting up a pond to use ecoChamber chambers is a simple process: Just pick the desired ecoChamber unit from the drop-down list, and specify the total number of chambers.
For chambers in a stone bed, just set the layout parameters and the chamber wizard will automatically layout the system and calculate the composite stage-storage curve for the chambers and the surrounding stone. The wizard can even be used to do basic cost estimating, including the cost of the chambers, excavation, stone, and other system components.
