Pumping tests analyses of a heterogeneous pore aquifer based on the Generalized Radial Flow model

open access: yesShuiwen dizhi gongcheng dizhi, 2022
Classical models such as the Theis model and Dupuit model have certain limitations in analyzing pumping test data of heterogeneous aquifers, and the obtained parameters are not suitable for characterizing the heterogeneous aquifers.

Experimental study on mechanism for pumping-induced land subsidence [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2020
Groundwater pumping can cause severe land subsidence, yet the mechanisms have not been completely clear. A laboratory physical model test was done to investigate the mechanism for pumping-induced land subsidence.

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

Pump and Valve Inservice Testing: How Pump and Valve Testing Evolved [PDF]

open access: yesASME/NRC 2017 13th Pump and Valve Symposium, 2017
The O&M Code was developed when it was decided to move Pump and Valve In-Service Testing Requirements from ASME Boiler and Pressure Vessel Code Section XI to a standalone Code. IST for Pumps was originally is ASME Section XI IWP and for Valves IWV. Safety and Relief Valves were a Power Test Code and not in the scope of the ASME Boiler and Pressure ...

Design of a Neural Network Model for the Determination of Unconfined Aquifer Parameters [PDF]

open access: yesمهندسی منابع آب, 2016
In this paper, an Artificial Neural Network (ANN) is designed for the determination of unconfined aquifer parameters: transmissibility, storage coefficient, specific yield, and delay index.

Efficiency Analysis of Aquifer Parameters of Different Wells in Khabat Basin

open access: yesZanco Journal of Pure and Applied Sciences, 2023
The study presented in this paper is the efficiency analysis of aquifer parameters in Khabat Basin through data collected from pumping test of the wells. The important indicator of the wells yield can be evaluated as the well efficient or not.

Multiple tests for identifying hydraulic conductivities of south and north boundary faults at Ganhe field, Huozhou Coal Electricity Group Co., Ltd, China

open access: yesGeomatics, Natural Hazards & Risk, 2018
Hydraulic conductivities of faults influence the mining design and safety of a coalmine badly. Results of field and indoor tests on hydraulic conductivities of the boundary faults in Ganhe coalfield in China are illustrated.

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.
