KGS-HighK: A Fortran 90 program for simulation of hydraulic tests in highly permeable aquifers

Estimation of Hydraulic Conductivity Using the Slug Test Method in a Shallow Aquifer in the Venetian Plain (NE, Italy)

DOI 10.4409/Am-045-12-0048 Abstract: The slug test offers a fast and inexpensive field method of obtaining localized hydraulic conductivity values. In this paper, we applied this procedure in a ‘fontanili’ zone located in the middle Venetian Plain (Villaverla, VI). In this site, 34 piezometers are present in a small area of 1.5 ha, which intercepts a shallow unconfined aquifer. The experimental...

Mathematical Derivations of Semianalytical Solutions for Hydraulic Tests in Highly Permeable Aquifers

Hydraulic tests in highly permeable aquifers

[1] A semianalytical solution is presented for a mathematical model describing the flow of groundwater in response to a slug or pumping test in a highly permeable, confined aquifer. This solution, which is appropriate for wells of any degree of penetration and incorporates inertial mechanisms at both the test and observation wells, can be used to gain new insights into hydraulic tests in highly...

Modeling slug tests in unconfined aquifers taking into account water table kinematics, wellbore skin and inertial effects

Two models for slug tests conducted in unconfined aquifers are developed by (a) extending the unconfined KGS solution to oscillatory responses, yielding a model referred to herein as the unified model, and (b) replacing the constant head condition with the linearized kinematic condition at the water table. The models can be used to analyze the full range of responses from highly oscillatory to ...

Numerical Modeling and Simulation of Highly Preheated and Diluted Air Combustion Furnaces

This paper presents some of the results of the modeling and simulation of an industrial furnace under the conventional combustion as well as under the highly preheated and diluted air combustion (HPDAC) conditions. The results are obtained using a computer program written by authors in FORTRAN language. It was found that, the HPDAC offers a more uniform and relatively moderate gas temperature p...
