Locations of the proposed\u003cbr\u003ewithdrawals are in the area of Leupp, Arizona, about 25 miles\u003cbr\u003efrom a perennial reach of lower Clear Creek. A simulation tool\u003cbr\u003ewas needed to determine possible effects of the proposed withdrawals\u003cbr\u003efrom the C aquifer, particularly the effects of depletion\u003cbr\u003eof streamflow in Clear Creek, Chevelon Creek, and the\u003cbr\u003eLittle Colorado River in the area of Blue Spring. A numerical\u003cbr\u003eground-water change model was developed for this purpose.\u003cbr\u003eThe model uses the U.S. Geological Survey finite-difference\u003cbr\u003emodel code MODFLOW-2000 and data sets representing key\u003cbr\u003efeatures of the C aquifer to simulate change in the system that\u003cbr\u003ewould result from withdrawing water at proposed locations.\u003cbr\u003eAquifer thickness was estimated from a hydrogeologic framework\u003cbr\u003emodel, and values of aquifer properties such as hydraulic\u003cbr\u003econductivity and specific yield were estimated from aquifer-test\u003cbr\u003edata. Two scenarios with differing withdrawal rates were run\u003cbr\u003efor a 101-year period that included 51 years of withdrawals followed\u003cbr\u003eby 50 years of no withdrawals. About 6 percent of the\u003cbr\u003eultimate volume of depletion occurs in the 101-year period for\u003cbr\u003eeither scenario. The maximum streamflow depletion rate for all\u003cbr\u003ereaches in the scenario with the greatest withdrawal rates was\u003cbr\u003ecomputed to be about 0.6 cubic foot per second. The depletion\u003cbr\u003erate was highest in lower Clear Creek, the reach that is closest\u003cbr\u003eto the well field. A model that simulates historical conditions\u003cbr\u003ewas used to help select the most reasonable parameter sets for a\u003cbr\u003eMonte Carlo analysis of computed stream depletions","brand":"The Delano Max Wealth Institute, LLC.","offers":[{"title":"Default Title","offer_id":47070526013680,"sku":"2940014451062","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014451062_p0.jpg?v=1763608814","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014451062","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
