The results of groundwater-availability scenarios run on the calibrated \nnumerical groundwater-flow model could be used by the Oklahoma Water Resources Board \nto evaluate the maximum annual yield of groundwater from the Rush Springs aquifer in \nOklahoma. A conceptual groundwater-flow model is a simplified description of the major \ninflow and outflow sources (hydrologic boundaries) of a groundwater-flow system as well \nas an accounting of the estimated mean flows from those sources (water budget) for a \nspecified period of time. The conceptual model was necessary to provide constraints used \nin the construction and calibration of a scientifically defensible numerical groundwater-flow \nmodel that reasonably represents the groundwater-flow system. \n\t\t\nA finite-difference numerical groundwater-flow model of the Rush Springs aquifer was \nconstructed by using MODFLOW-2005 with the Newton formulation solver (MODFLOW-NWT). \nData inputs for each package were specified in machine-readable text files. The numerical \nmodel of the Rush Springs aquifer had 1,362 rows, 1,083 columns, about 554,000 active \ncells of 500 by 500 ft, and 3 convertible layers. The top layer (layer 1) represented the \nPermian-age Cloud Chief Formation. The Rush Springs aquifer is composed of Permian-age \nWhitehorse Group. The second layer (layer 2) represented the undifferentiated Quaternary-age \nalluvium and terrace deposits, as well as the upper 30 ft of the Whitehorse Group. The \nbottom layer (layer 3) represented the remainder of the Rush Springs Formation. The model \nactive area was modified from Neel and others (2018). The numerical model was temporally \ndiscretized into 444 monthly transient stress periods representing the period 1979-2015. An \ninitial steady-state stress period, in which the groundwater-flow equation had no storage \ncomponent, represented mean annual inflows to and outflows from the aquifer and produced \na solution that was used as the initial condition for subsequent transient stress periods. The \nnumerical model was constructed in units of meters and days.
