Abstract: From a water management perspective, the bulk quantity of water moved and where it has been sourced from are more important than simply estimating drawdown effects due to pumping. This note considers the problem of estimating ...

Abstract: In this paper, we consider Hunt’s stream depletion model, which models the effect of pumping adjacent to an infinitely long stream. In this model it is assumed that drawdown is described by an extension of the Theis equation. ...

Abstract: We consider the case of pumping a semiconfined aquifer overlain by a phreatic aquifer hydraulically connected to an infinitely long and straight stream. The hydraulics of the system are described by a linearized model in ...

Abstract: Semianalytic formulas are obtained for flow to a well screened in a leaky aquifer that was overlain by an aquitard and phreatic aquifer and underlain by a second aquitard and leaky aquifer. Formulas are also obtained for ...

Abstract: This study considers the problem of quantifying stream depletion from pumping test data. Bayesian inference is used to quantify the posterior uncertainty of parameters for a simple vertically heterogeneous aquifer model, ...

Abstract: When fitting hydraulic models of groundwater flow to pumping test data, Bayesian inference provides a framework for quantifying the posterior uncertainty of aquifer parameters estimated from data and the most likely range ...

Abstract: This study considers the estimation of aquifer parameters for a spatially heterogenous aquifer from pumping test data. An approach is proposed that is based on modeling the unknown parameters as smooth Markov random fields. ...

Abstract: Calibration of distributed parameter groundwater models in the Bayesian framework using Markov-chain Monte Carlo (MCMC) random sampling is often hampered by the large number of simulations required to make reliable uncertainty ...

Abstract: We document the development and application of a one-dimensional flow model of the Chesapeake and Delaware Canal based on the dynamic form of the St. Venant equations. Model geometry is based on hydrographic surveys obtained ...
