Summary
A 2016 update was made to the GSFLOW model documented in SIR 2013-5159, which is available online ( https://pubs.usgs.gov/sir/2013/5159/ ). The original GSFLOW model was created to simulate climate changes effects on streamflow, lake budgets, and stream temperature in the Trout Lake Watershed, Wisconsin. The computer code GSFLOW (Groundwater/Surface-water FLOW) was used to simulate the coupled hydrologic system; a surface-water model represented hydrologic processes in the atmosphere, at land surface, and within the soil-zone, and a groundwater-flow model represented the unsaturated zone, saturated zone, stream, and lake budgets. The coupled GSFLOW model was calibrated by using heads, streamflows, lake levels, actual evapotranspiration [...]
Summary
A 2016 update was made to the GSFLOW model documented in SIR 2013-5159, which is available online ( https://pubs.usgs.gov/sir/2013/5159/ ). The original GSFLOW model was created to simulate climate changes effects on streamflow, lake budgets, and stream temperature in the Trout Lake Watershed, Wisconsin. The computer code GSFLOW (Groundwater/Surface-water FLOW) was used to simulate the coupled hydrologic system; a surface-water model represented hydrologic processes in the atmosphere, at land surface, and within the soil-zone, and a groundwater-flow model represented the unsaturated zone, saturated zone, stream, and lake budgets. The coupled GSFLOW model was calibrated by using heads, streamflows, lake levels, actual evapotranspiration rates, solar radiation, and snowpack measurements collected during water years 1998–2007; calibration was performed by using advanced features present in the PEST parameter estimation software suite. The updated model for this data release extended the simulation period to 1975-2015 (first 13 years discarded as spin-up) as compared to 1988-2007 (first 12 years discarded as spinup) for the original GSFLOW model of SIR 2013-5159.
The model was updated to better simulate groundwater inflow to five lakes (Allequash, Big Muskellunge, Crystal, Sparkling, and Trout Lakes) in the Northern Temperate Lakes long term ecological research site for the lake nitrogen study discussed in the Powers and others (2017) journal article (https://doi.org/10.1002/lol2.10048). The updated model extended the simulation period to 1975-2015 (first 13 years discarded as spin-up) as compared to 1988-2007 (first 12 years discarded as spinup). The development of the original model input and output is discussed in SIR 2013-5129 with updates discussed in the readme.txt file of this model archive. The updated input and output files are included in this data release.
