The site model files \nprovided include both calibrated and uncalibrated simulations of various steady-state and transient hydrologic \nconditions. Simulations were accomplished with equivalent porous media models that allow laminar flow only \n(MODFLOW) or laminar and non-laminar flow in a model layer (MODFLOW-CFP mode 2) and hybrid model \nsimulations (MODFLOW-CFP mode 1 one-dimensional pipe network linked to equivalent porous media model). \nThe test examples of the application of equivalent porous media model (the sponge) with and without turbulence \nand a hybrid model (sponge with pipes) to the Woodville Karst Plain near Tallahassee, Florida, indicated that for \nannual, monthly, or seasonal average hydrologic conditions, all methods met calibration criteria (matched \nobserved water levels and average flow). Thus, the increased effort, such as the collection of data on conduit \nlocation and the computational time of a hybrid model, is not necessary for simulation of average hydrologic \nconditions (simulation of non-laminar flow was not critical). However, simulation of a large storm event in the \nWoodville Karst Plain with daily stress periods (52-day period beginning August 13, 2008) indicated that \nturbulence is important for matching daily springflow hydrographs and models calibrated to average conditions \ndid not match daily storm spring hydrographs. All models were developed from an equivalent porous media \nmodel for the area calibrated by J. Hal Davis, USGS, Tallahasee Florida Office that is documented in Davis, \nJ.H., Katz, B.G., and Griffin, D.W., 2010, Nitrate-N movement in groundwater from the land application of \ntreated municipal wastewater and other sources in the Wakulla Springs springshed, Leon and Wakulla \nCounties, Florida, 1966\u20132018: U.S. Geological Survey Scientific Investigations Report 2010\u20135099, 90 p. \n(https://pubs.usgs.gov/sir/2010/5099/).
