This webcast is the latest effort in WEF / WERF collaboration with the focus of bringing key cutting edge research to the water sector. The event will present the results of WERF research producing a “Nutrient Modeling Toolbox” and associated guidance for selection, development, and application of the models in the toolbox on a site-specific basis. This project was intended to fill a critical gap in guidance for the use of load-response models to derive numeric nutrient criteria (NNC) and other types of quantitative nutrient-related goals. This important research is likely going to be a “game changer” for American clean water partners and implementation of the Clean Water Act. 

The webcast will describe and demonstrate the Model Selection Decision Tool (MSDT) which was designed to help local governments, utilities, states, and other stakeholders select modeling approaches for their site from the suite of models included in the Nutrient Modeling Toolbox, and will demonstrate the use of the MSDT. Two case study examples will be used to illustrate how the MSDT can aid model selection by matching key technical and regulatory considerations to available models. Model selection factors considered within the MSDT include waterbody type, ecological response indicators (endpoints), type of application (NNC development, or loading assessment without NNC - screening, planning, or regulatory levels), physical and temporal variability, and secondary questions used to further refine the list of applicable models. Speakers will describe how regulatory considerations affect the different steps of the modeling process, from model selection to model application for deriving NNC and/or allowable nutrient loads and will use case studies to explain where use of this tool fits into the regulatory process.
