Hydrologic behaviour and hydraulic properties of a patterned fen in Saskatchewan
… Hydraulic conductivity, transmissivity, and storativity were determined through use of a surface loading test, pumping tests, and an enclosed field drainage test. None of these field tests have been previously described in the literature as having been used in peat environments. The combined …

A method using drawdown derivatives to estimate aquifer properties near active groundwater production well fields
… to estimate the aquifer transmissivity and storativity. The forward model consists of an initial water level (or a recoverable water level drift function), an analytical solution for aquifer drawdown, and a correction term for well loss. The aquifer drawdown component is based on …

Epikarst control on flow and storage at James Cave, VA: an analog for water resource characterization in Shenandoah Valley karst
… and permeability of flow paths, and evaluate storativity in the epikarst. Results demonstrate that after significant seasonal recharge, which occurs in the late winter and early spring, the epikarst can temporarily store a significant portion of recharge in low permeability flow paths. …

Implications of permeability uncertainty within engineered geologic fluid systems
… uncertainty has on the injectivity and storativity of the CRBG as a storage reservoir, (3) a modeling study utilizing 1-, 2-, and 3-D numerical models to investigate how the thermal signature of the CO2-water system evolves during a CO2 injection, and (4) a Monte Carlo-type modeling …

Hydrogeological characterisation and water supply potential of Lebalelo South, Limpopo Province of South Africa
… using AQTESOLVE. Aquifer transmissivity, storativity, internal and external hydraulic boundaries were determined from the data. The transmissivity in the area ranges from 0.08 to 124.7 m2/day. The aquifer types in the area are double porosity aquifer, radial flow aquifer with single …

Impact of uncertain input on parameter estimation in groundwater model
… parameters like transmissivity and storativity are estimated using regression-based inverse methods, it is assumed that all other parameters and quantities are known. In particular, it is assumed that pumping rates are known. This will not be a valid assumption for groundwater basins …

Development of risk-based groundwater operating rules: a case study of Siloam Village, South Africa
… for estimating hydraulic characteristics (storativity, transmissivity and hydraulic conductivity) based on Aquifer Test Solver (AQTESOLV) Pro version 4.5. Limited groundwater levels and rainfall data were infilled and/or extended using Output Error-Nonlinear Hammerstein Weiner (OE-NLHW) and …

Development of a Groundwater Flow Model for Hungry Valley, Washoe County, Nevada
… are characterized by low transmissivities with storativity values indicating the aquifers to be confined. Groundwater pumping began in 1991 and a decline in static water levels began to occur. With an alternate pumping strategy implemented in 2004 and additional production wells implemented in …

Oil Potential of Middle Cretaceous Tight Carbonate in Mexico
… of interest, including fracture transmissivity, storativity ratio, skin and the extrapolated pressure (p*). The testing suggests that although natural microfractures are present, they tend to close once the well goes on production. Fracture permeabilities (k2) from well testing are very low, in …

The role of well testing in geothermal resource assessment
… tests range from 1 Dm to 30 Dm, whereas the storativity ranges from 5•10-8 m/Pa to 2•10-7 m/Pa. The reservoir temperature estimate is between 280 oC and 340 oC. The average capacity for producing electricity is estimated around 10 MWe per well. The resource assessment is performed for two …

Characterizing Stream-Aquifer Interactions in the Pedernales Watershed in Central Texas
… the stream and watershed divide, and S is the storativity of the aquifer was estimated as 0.0403/d and the watershed K value was 23.15 days/log cycle. It is concluded that the Hensel Sand (rock formation) of Cretaceous age is the primary source of baseflow to the Pedernales River above the …

Groundwater Resource Supply Augmentation: A Case Study of Dzamba and Mabulo Villages in Vhembe District Municipality, Limpopo Province, South Africa
… m2/day and 1,59 m2/day, respectively. While the Storativity (S) was 0,00003 (Theis method) and 0,4 x 10-7 (Cooper-Jacobs). The study recommends submitting future groundwater project reports within the study area to the Department of Water and Sanitation or Local Municipality to update the …

The effects of seismic blasting on shallow water wells and aquifers in western North Dakota
… Consequently, values for transmissivity, storativity, and specific yield were unobtainable.</p> <p>During the pumping tests, no significant long term chemical or mineralogical equilibrium changes were observed which could be attributed to the blasting. Water quality changes resulted from …
