Abstract: A drainage unit has a plurality of modules defining channels with arced or flared surfaces longitudinally spaced from one another for installation into a ground excavation. The spaced modules may be aligned on a longitudinally support pipe that may provide a fluid connection between the channels. The adjacent surfaces of successive modules are spaced from each other a non-constant distance across the laterally transverse thickness or height. Filtration fabric that allows fluid flow therethrough while substantially filtering surrounding soil or other back fill is wrapped around each of modules. The flared and/or arced configuration of the modules defining channels allows for increased surface area interfacing between the channels and soil and a corresponding reduction in laterally transverse footprint.

Abstract: A system, methodology, and programming logic for active stormwater controls to optimize sizing and design of Hydromodification Management (HM) structural Best Management Practices (BMPs) to achieve optimal flow duration control. Control logic enables the controlled release of stormwater from a BMP in a manner most akin to pre-development flow duration curves. Inputs to this logic include: flow duration curves based on continuous hydrologic simulation for pre- and post-development conditions; real-time measurement of water level within the BMP; and real-time measurement of discharge entering the BMP. This control logic can interact with control logic for other stormwater management objectives, such as harvest and reuse, infiltration, and combined sewer overflow prevention, and respective inputs, such as real-time weather forecast data, precipitation gage data, downstream flow gauge data, and water quality data, to meet those design objectives as well.
