{"product_id":"2940014431699","title":"An Aquifer-Test Preprocessor for the Ground-Water Flow Model Calibration Program MODOPTIM and its Application to a Well Field in Duval County, Florida","description":"A method was developed to generate the input files\u003cbr\u003eneeded to compute the hydraulic properties from\u003cbr\u003eaquifer-performance test data for confined aquifers\u003cbr\u003e(such as the Floridan aquifer system) by using an\u003cbr\u003eaquifer-test preprocessor for the computer program\u003cbr\u003eMODOPTIM. MODOPTIM is a non-linear, groundwater\u003cbr\u003eflow model calibration and management tool that\u003cbr\u003euses MODFLOW-96 to simulate cylindrical or axisymmetric\u003cbr\u003eflow in the vicinity of a pumping well for any\u003cbr\u003eaquifer-well configuration. The preprocessor assumes\u003cbr\u003ethat the production well penetrates either the Upper\u003cbr\u003eFloridan aquifer only, or penetrates both the Upper\u003cbr\u003eFloridan aquifer and Lower Floridan aquifer. The\u003cbr\u003eproduction well may fully or partially penetrate either\u003cbr\u003eaquifer. Input files needed to run MODOPTIM are\u003cbr\u003egenerated by the aquifer-test preprocessor and the\u003cbr\u003eoptimal hydraulic parameter values are computed by\u003cbr\u003erunning MODOPTIM, which determines the set of\u003cbr\u003eparameter values that minimizes the sum-of-squared\u003cbr\u003edifferences between simulated and measured drawdowns\u003cbr\u003eby using an iterative quasi-Newton algorithm.","brand":"The Delano Max Wealth Institute, LLC.","offers":[{"title":"Default Title","offer_id":47146027352304,"sku":"2940014431699","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014431699_p0.jpg?v=1763608360","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014431699","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
