Determination of Unconfined Aquifer Parameters Using Boulton, Neuman and Streltsova Methods
Journal of King Saud University: Engineering Sciences, 1993 Analysis of pumping test data to estimate aquifer parameters is normally carried out using standard procedures such as the Theis or Jacob method. These methods, however, were derived with assumptions regarding the type of aquifer and wells that may not ...

In Situ CO<sub>2</sub>-Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers. [PDF]
Adv Sci (Weinh)A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Estimations of tidal characteristics and aquifer parameters via tide-induced head changes in coastal observation wells [PDF]
Hydrology and Earth System Sciences, 2011 The groundwater fluctuations due to tidal variations at an observation well in a coastal aquifer can be used to determine the tidal characteristics and aquifer parameters without conducting an aquifer test.

Invariant Imbedding and the Identification of Aquifer Parameters
IFAC Proceedings Volumes, 1977 AbstractThe technique of invariant imbedding is applied to the problem of identifying the parameters in an unconfined aquifer system. This new technique is shown to be a very effective way of converting field observations based upon pumping tests into the desired aquifer parameters. The procedure is straightforward as it requires neither curve plotting

Estimation of Parameters in Groundwater Modeling by Particle Filter linked to the meshless local Petrov-Galerkin Numerical Method [PDF]
Journal of Hydraulic Structures, 2021 The present study employs a mathematical method, i.e. Particle Filter (PF), to accurately estimate the parameters of three standard aquifers. The method is linked to a new developed numerical method, i.e.
