The groundwater flow model uses the U.S. Geological Survey\u2019s \nMODFLOW-NWT modeling code.  This model explicitly includes all high-capacity \nwells in the model domain and simulates seasonal variations in recharge and well \npumping.  The model represents the Little Plover River, and other significant streams \nand drainage ditches in the model domain, as fully connected to the groundwater system, \ncomputes stream base flow resulting from groundwater discharge, and routes the flow \nalong the stream channel.  A separate soil-water-balance (SWB) model was used to \ndevelop a groundwater recharge array as input for the groundwater flow model.  The \nSWB model uses topography, soils, land use, and climatic data to estimate recharge \nas deep drainage from the soil zone.  The SWB model explicitly includes recharge \noriginating as irrigation water, and computes irrigation using techniques similar to \nthose used by local irrigation operators.\n\t\t\nhe groundwater flow model was calibrated to monthly stress periods with time steps \nranging from 1 to 16 days.  The groundwater model was calibrated to water-level and \nstreamflow data collected during 2013 and 2014 by adjusting model parameters \n(primarily hydraulic conductivity, storage, and recharge) until the model produced a \nconditionally optimal fit between field observations and model output, subject to \nconsistency with previous published geologic studies.  Calibration was performed \nunder both steady and transient conditions and used a sophisticated parameter-estimation \nprocedure (PEST) for the calibration process and to identify important model parameters.  \nWith respect to the Little Plover River the two most important parameters are the global \nrecharge multiplier and the hydraulic conductivity of the stream bed.  The calibrated model \nproduces water level and mass balance results that are consistent with field observations \nand with previous studies of the area.
