Assessing The Difference Between Soil And Water Assessment Tool (Swat) Simulated Pre-Development And Observed Developed Loading Regimes, Sean J. Zeiger, Jason A. Hubbart
Assessing The Difference Between Soil And Water Assessment Tool (Swat) Simulated Pre-Development And Observed Developed Loading Regimes, Sean J. Zeiger, Jason A. Hubbart
Faculty & Staff Scholarship
The purpose of this research was to assess the difference between Soil and Water Assessment Tool (SWAT) simulated pre-development and contemporary developed loading regimes in a mixed-land-use watershed of the central United States (US). Native land cover based on soil characteristics was used to simulate pre-development loading regimes using The Soil and Water Assessment Tool (SWAT). Loading targets were calculated for each major element of a pre-development loading regime. Simulated pre-development conditions were associated with increased retention and decreased export of sediment and nutrients when compared to observed developed conditions. Differences between simulated pre-development and observed developed maximum daily yields …
Assessing Environmental Flow Targets Using Pre-Settlement Land Cover: A Swat Modeling Application, Sean J. Zeiger, Jason A. Hubbart
Assessing Environmental Flow Targets Using Pre-Settlement Land Cover: A Swat Modeling Application, Sean J. Zeiger, Jason A. Hubbart
Faculty & Staff Scholarship
Determining environmental flow requirements to sustain aquatic ecosystem health remains a challenge. The purpose of this research was to quantify the extent of current flow alterations relative to baseline hydrologic conditions of a simulated historic flow regime prior to anthropogenic flow disturbance (i.e., pre-settlement flows). Results allowed assessment of the efficacy of environmental flow targets based on pre-settlement land cover in a contemporary mixed-land-use catchment (i.e., urban, agricultural, and forested). Pre-settlement flows were simulated using the Soil and Water Assessment Tool (SWAT). Pre-settlement land cover, based on soil physical characteristics, was used to simulate pre-settlement flows with the SWAT model. …
