http://gmstutorials-10.4.aquaveo.com/MODFLOW-DRTPackage.pdf WebA drain can be used to represent an artesian well . It may even be located in a deep layer and flow uncontrolled at the surface. If appropriate, a portion of that flow can be recharged to the shallow system. MODFLOW 2000 allows the user to specify a fraction (between 0 and 1.0) of the drain outflow to be returned as recharge to a specified cell.
