HydroCAD Supports
ADS Aquabox
HydroCAD provides full support for the stormwater storage products offered by Advanced Drainage Systems, Inc. including N-12 pipe and the StormTech and Aquabox chambers.
This partnership allows ADS products to be easily used within any HydroCAD model for stormwater storage, detention, or infiltration. HydroCAD includes complete ADS storage definitions, plus an interactive chamber wizard for easy layout, pricing, and modeling of underground storage systems.
HydroCAD 10.2-8a is required to model the Aquabox chamber with the usual stone envelope. The upcoming HydroCAD 10.2-9a release will include the separate base plate used with all half-height configurations. If you have an earlier version of HydroCAD you need to update in order to model the latest chambers.
How storage is modeled
Stormwater storage typically appears in a HydroCAD model as part of the storage definition for a "pond". In the simplest case, HydroCAD calculates the total available storage, including the interior of the chambers, plus the void space in any surrounding stone. For a more complete analysis, a full stage-storage curve is calculated so that an inflow or runoff hydrograph can be routed 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 HydroCAD 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.
But the most significant feature is the ability to embed (bury) chambers in a bed of 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.
HydroCAD can also model almost any imaginable storage arrangement, including layered chambers of different sizes combined with auxiliary storage from adjacent pipes and catch basins, and even the above-ground areas (parking lot) that may provide overflow storage for certain events.
Modeling
the ADS Aquabox
Setting up a pond to use the Aquabox is a simple process with the HydroCAD Chamber Wizard: Just pick the "ADS Aquabox" from the drop-down list and select the system height. When you enter the number of rows and chambers per row, HydroCAD will automatically draw the system and perform complete stage-storage calculations, including the usual stone bed.
If you intend to model flow through the system, you can define the appropriate exfiltration and outlet controls. This will give you a complete "pond" node that can be used within a larger HydroCAD model.
