Spatial Variability and Prediction Modeling of Groundwater Arsenic Distributions in the Shallowest Alluvial Aquifers in Bangladesh
Arsenic Bangladesh distribution spatial variability semivariogram prediction models
2015/8/13
Elevated arsenic in groundwater is the greatest environmental problem in Bangladesh. Spatial variability of arsenic in groundwater has been examined by semivariogram analysis that revealed high degree...
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
When a test pumping from an artesian aquifer has been performed, the result
will often exibit a more or less confusing variety of features. The reason for
this may, of course, be that the geological...
Drawdowns at the Free Water Table During Pumping Tests in Artesian and Semiarteian Aquifers
Free Water Table Pumping Tests Artesian Semiarteian Aquifers
2009/10/28
In an earlier paper I have shown an example of how long term drawdowns can
be used for the computation of long term storage in artesian and semiartesian
areas. In most cases the long term storage is...
Finite Element Analysis of Square Aquifers Containing Pumped Wells and Comparison with Finite Difference Method
Finite Element Analysis Square Aquifers Pumped Wells
2009/10/28
The numerical solution of the behaviour of discrete time steps in digital computer
analysis of square aquifers containing pumped wells is examined by
using the finite element method with a 4 node li...
Digital Simulation Model for Brine Coning in Unconfined Anisotropic Aquifers
Digital Simulation Model Unconfined Anisotropic Aquifers
2009/10/27
A digital simulation model has been presented for locating the steady state
stable brine cone position beneath partially penetrating wells tapping from the
fresh water zone overlying a saline zone i...
An Indirect Method for Determination of the Parameters of Flood Plain Aquifers
Indirect Method Determination Flood Plain Aquifers
2009/10/27
An indirect method of determining flood plain aquifer parameters from estimated
autocorrelation of groundwater table data is presented. For this purpose
a stream-aquifer system is approximated by a ...
Unsteady Flow to a Non-Penetrating Large Diameter Well in Extensive Aquifers
Unsteady Flow Non-Penetrating Large Diameter Well Extensive Aquifers
2009/10/27
Non-equilibrium groundwater movement equations are written explicitly for
the continuity and flow laws in the case of a non-penetrating large diameter
well discharging from extensively thick confine...
