Coupling Physical and Machine Learning Models with High Resolution Information Transfer and Rapid Update Frameworks for Environmental Applications
… and Water Assessment Tool-Variable Source Area (SWAT-VSA) model with the Climate Forecast System Reanalysis (CFSR) model and the Global Forecast System (GFS) model short-term weather forecast, to develop a CSA prediction tool designed to assist producers, landowners, and planners in identifying …

Essays on Water Quality Management for the Chesapeake Bay Watershed
… and Water Assessment Tool-Variable Source Area (SWAT-VSA) model to predict crop yields and N export. Costs of targeting and uniform placement of BMPs across the entire study area (4.23 km2) are compared under historical and future climate scenarios. We find that with a goal of reducing N loadings …

Enhanced Soil Moisture and Streamflow Estimation in Ungauged or Data-Scarce Watersheds
… frameworks like Soil and Water Assessment Tool (SWAT). Clear conceptualization is critical to realize adequate representation of internal hydrologic processes, particularly in saturated excess runoff dominated watersheds where the spatio-temporal dynamics of saturated areas influence both the …

Legacy Nutrient Management and Remediation in Diverse Agricultural Watersheds
… phosphorus export in a variable source area (VSA)–dominated agricultural watershed within the Lake Champlain Basin. Using the SWAT–VSA model calibrated for streamflow and total phosphorus (TP), this chapter examines long-term phosphorus export under current agricultural management. Results …

Quantifying the Impact of Climate Change on Water Availability and Water Quality in the Chesapeake Bay Watershed
… for the Soil and Water Assessment Tool (SWAT) model. The new routine predicts N2O and di-nitrogen (N2) emissions by coupling the C and N cycles with soil moisture, temperature, and pH in SWAT. The model uses reduction functions to predict total denitrification (N2 + N2O production) and …
