Adjoint Method to Simulate Stream Depletion Due to Pumping in a Non-linear Coupled Groundwater and Surface Water System
The goal of this paper is to introduce an adjoint approach for calculating stream depletion in a river that is hydraulically connected to an aquifer. This paper presents the coupled forward and adjoint equations of flow in an unconfined aquifer, a confined aquifer, and in a river. Flow in the river is assumed to follow Manning’s equation, and the river is assumed to have a wide, rectangular cro...
متن کاملEffects of Streambed Conductance on Stream Depletion
Stream depletion, which is the reduction in flow rate of a stream or river due to the extraction of groundwater in a hydraulically connected stream-aquifer system, is often estimated using numerical models. The accuracy of these models depends on the appropriate parameterization of aquifer and streambed hydraulic properties. Streambed conductance is a parameter that relates the head difference ...
متن کاملMODELING OF GROUNDWATER FLOW OVER SLOPING BEDS IN RESPONSE TO CONSTANT RECHARGE AND STREAM OF VARYING WATER LEVEL
This paper presents an analytical model characterizing unsteady groundwater flow in an unconfined aquifer resting on a sloping impervious bed. The aquifer is in contact with a constant water level at one end. The other end is connected to a stream whose level is increasing form an initial level to a final level at a known exponentially decaying function of time. Moreover, the aquifer is repleni...
متن کاملRelationship between River Flow, Rainfall and Groundwater pumpage in Mikkes Basin (Morocco)
This paper investigates the relationship between river flow, rainfall and groundwater pumpage in the Mikkes stream during the period 1968-2009. The Mikkes basin is located in the north center of Morocco and consists of three different zones that represent diversified geologies. This basin includes a phreatic and confined aquifer in Saïs basin and a shallow aquifer in the Tabular Middle Atlas. A...
متن کاملModeling the Factors Impacting Pesticide Concentrations in Groundwater Wells.
This study examines the effect of pumping, hydrogeology, and pesticide characteristics on pesticide concentrations in production wells using a reactive transport model in two conceptual hydrogeologic systems; a layered aquifer with and without a stream present. The pumping rate can significantly affect the pesticide breakthrough time and maximum concentration at the well. The effect of the pump...
