The Step-Drawdown Test and Non-Darcian Flow:A Critical Review of Theory,Methods and Practice
Step-Drawdown Test Non-Darcian Flow Critical Review
2009/10/28
Step-drawdown tests are usually carried out with succeeding steps of increased
pumping yield, each step of equal duration of 1 hour. The background for this
procedure 1s reviewed, and it is shown, t...
A Test of Snowmelt-Runoff Model for a Major River Basin in Western Himalayas
Snowmelt-Runoff Model Major River Basin Western Himalayas
2009/10/27
In the Snowmelt-Runoff Model (SRM), the estimate of discharge volume is
based on temperature condition in the form of degree days which are used to
melt the snowpack in the area of the basin covered...
Tracer Test in Fractured Chalk 2.Numerical Analysis
Tracer Test Fractured Chalk Numerical Analysis
2009/10/26
A two-well tracer test carried out in fractured chalk was analyzed using a threedimensional
finite-difference model for flow and transport which, was constructed
on the basis of the geological and h...
Tracer Test in Fractured Chalk 1.Experimental Design and Results
Tracer Test Fractured Chalk Experimental Design
2009/10/26
A two-well tracer test was conducted in eastern Denmark, in which a short
duration pulse of lithium chloride was injected into a recharge well and made to
flow through a fractured chalk aquifer to a...
Hydrogeophysical Concepts in Aquifer Test Analysis
Hydrogeophysical Concepts Aquifer Test Analysis
2009/10/26
Aquifer test data analysis is an art leading to reliable hydraulic parameter
identifications rather than a mechanical curve fitting. Most often aquifer test
data processing is achieved by matching t...
DETERMINATION OF THE SKIN FACTOR IN THE EARLY PORTION OF AN AQUIFER TEST
AQUIFER TEST Unsteady flow infinite system
2009/10/13
Unsteady flow to a single well fully penetrating a confined aquifer (homogeneous and isotropic) is analyzed. The well is assumed to be located in an infinite system; that is, the effect of boundaries ...
Towards a hydrological classification of European soils：preliminary test of its predictive power for the base flow index using river discharge data
European soils base flow hydrological classification
2009/5/12
Predicting discharge in ungauged catchments or contaminant movement through soil requires knowledge of the distribution and spatial heterogeneity of hydrological soil properties.
Because hydrolog...
Influence of forest disturbance and test application of PnET model for determining long-term impact influences
forest disturbance nitrate stream chemistry PnET biomass
2009/4/2
The influence of forest disturbance was reviewed and examined applying the PnET model developed in the USA. Forest disturbance has a significant impact on nutrient cycling due to the interruption of p...
Influence of parameter estimation uncertainty in Kriging: Part 2 - Test and case study applications
yearly rainfall maximum likelihood
2009/3/23
The theoretical approach introduced in Part 1 is applied to a numerical example and to the case of yearly average precipitation estimation over the Veneto Region in Italy. The proposed methodology was...
Establishment success in young cladoceran communities: An experimental test
Establishment success young cladoceran communities
2014/5/4
We tested the relative importance of regional and local factors in determining zooplankton community composition in an enclosure experiment. In this experiment, we assessed establishment success of im...
