Determination of Aquifer Transport Parameters

Journal of the Hydraulics Division, 1979
The mathematical simulation of dispersive pollution transport for any ground-water field is possible provided all physical parameters appearing in the governing partial differential equation are defined. The present work deals with determining the flow velocity, flow direction, and longitudinal and transverse dispersion coefficients. A use of the multi-

Sequential estimation of aquifer parameters

Water Resources Research, 1988
A two‐dimensional “inverse” or “parameter estimation” code was developed for use in the Basalt Waste Isolation Project site characterization program. The method uses a sequential least squares algorithm that incorporates a finite element groundwater flow code.

Aquifer Parameter Estimation from Surface Resistivity Data

Groundwater, 2003
Abstract This paper is devoted to the additional use, other than ground water exploration, of surface geoelectrical sounding data for aquifer hydraulic parameter estimation. In a mesoscopic framework, approximated analytical equations are developed separately for saline and for fresh water saturations.

Identification of parameters in unconfined aquifers

Journal of Hydrology, 1985
A method is presented for identification of parameters in unconfined aquifers from pumping tests, based on the optimisation of the objective function using the least squares approach. Four parameters are to be evaluated, namely: The hydraulic conductivity in the radial and the vertical directions, the storage coefficient and the specific yield.
