{"product_id":"2940014374828","title":"A Computer Program for Predicting Recharge with a Master Recession Curve","description":"Water-table fluctuations occur in unconfined aquifers owing to ground-water recharge following precipitation and infiltration, and ground-water discharge to streams between storm events. Ground-water recharge can be estimated from well hydrograph data using the water-table fluctuation (WTF) principle, which states that recharge is equal to the product of the water-table rise and the specific yield of the subsurface porous medium. The water-table rise, however, must be expressed relative to the water level that would have occurred in the absence of recharge. This requires a means for estimating the recession pattern of the water-table at the site. For a given site there is often a characteristic relation between the water-table elevation and the water-table decline rate following a recharge event. A computer program was written which extracts the relation between decline rate and water-table elevation from well hydrograph data and uses it to construct a master recession curve (MRC).","brand":"The Delano Max Wealth Institute, LLC.","offers":[{"title":"Default Title","offer_id":47073998930160,"sku":"2940014374828","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014374828_p0.jpg?v=1763607317","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014374828","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
