Bayesian estimation of the transmissivity spatial structure from pumping test data [PDF]

open access: yes, 2017
Estimating the statistical parameters (mean, variance, and integral scale) that define the spatial structure of the transmissivity or hydraulic conductivity fields is a fundamental step for the accurate prediction of subsurface flow and contaminant ...

Hydraulic Conductivity Imaging from 3-D Transient Hydraulic Tomography at Several Pumping/Observation Densities [PDF]

open access: yes, 2013
[1] 3-D Hydraulic tomography (3-D HT) is a method for aquifer characterization whereby the 3-D spatial distribution of aquifer flow parameters (primarily hydraulic conductivity, K) is estimated by joint inversion of head change data from multiple ...

Hydrogeological characterization and parameters estimation of the aquifer close to the Adige River (Verona, Italy) for the design of deep excavations

open access: yesAcque Sotterranee, 2019
In the framework of the final design of a new hydroelectric plant close to the existing dam on the Adige River in the municipality of San Giovanni Lupatoto (VR, Italy), the design of deep excavations in loose sediments below groundwater level, and the ...

Haus/Gross-Pitaevskii equation for random lasers [PDF]

open access: yes, 2010
We report on experimental tests of the trend of random laserlinewidth versus pumping power as predicted by an Haus master equation that is formally identical to the one-dimensional Gross- Pitaevskii equation in an harmonic potential. Experiments are done

Formulating surrogate pumping test data sets to assess aquifer hydraulic conductivity

open access: yesJournal of Hydrology X, 2018
A hypothesis to estimate hydraulic conductivity from surrogate pumping tests formulated using routinely monitored pumping rates and hydraulic heads is tested. The data set of a surrogate pumping test contains only a few late-time drawdowns represented by

Optimization of Energy Consumption in the Pumping Station Supplying Two Zones of the Water Supply System

open access: yesEnergies, 2022
Water supply pumping stations are among the main energy-consuming elements in the water supply system. The energy optimization of a pumping station can significantly affect the energy consumption of a water utility.

Periodic pumping tests [PDF]

open access: yesGeophysical Journal International, 2006
SUMMARY We performed pumping tests with a periodic succession of injection and production intervals in a field of three shallow boreholes penetrating a jointed sandstone formation. Tests were conducted at periods ranging from 10 to 5400 s and pumping rates between 5 and 20 l min−1.

Freshwater-salt water interface dynamics during pumping tests

open access: yesAcque Sotterranee, 2019
Freshwater-salt water interface (FSI) location is very important information for decision maker in managing coastal aquifer system, however, its temporal change have been hard to get using conventional method such as EC monitoring at one or several fixed

Permeability coefficient tests in non-cohesive soils

open access: yesPrzegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2020
The paper aims to comparison the permeability coefficient in non-cohesive soils by the method of test pumping and based on tests in a consolidometer. The tests were carried out on 18 types of non-cohesive soils with different fraction. Pumping tests were

Ergodicity of pumping tests [PDF]

open access: yesWater Resources Research, 2007
Standard interpretations of pumping tests in heterogeneous formations rely on effective representations of porous media, which replace spatially varying hydraulic properties with their constant counterparts averaged over the support volume of a test. Rigorous approaches for deriving representative (effective, apparent, upscaled, etc.) parameters employ
