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.

Abstract: An automated landfill gas wellhead monitoring and control system includes a field monitoring and control system (FMCS) that receives landfill gas condition data and that controls an automated gas control valve on a wellhead as a function thereof. A remote monitoring control system (RMCS) is in communication with the FMCS and provides other data obtained from sources outside of the landfill. This additional data is used by the FMCS to control the gas control valve and the system provides a preventative configuration based on a predicted condition.
