A. nalysis of. L. itholog. D. ata The development of groundwater requires knowledge about the characteristics of the subsurface aquifer parameters. So, analysis of litholog and static water level data are very important for the measurement of aquifer parameters.
Aquifer well pumping test method is a widely adopted method to determine the aquifer parameters in groundwater hydrology. The detailed description about determining aquifer properties from pumping test data can be found in many groundwater hydrology text books1, 2. Equilibrium equation known as Thiem3 equation can be used to determine the hydraulic. The pumping tests are commonly used to estimate the transmissivity and storage coefficient of the aquifers which are principal parameters in aquifer modeling and management. In this study, a simple derivative-based method is presented based on the least squares optimization technique to estimate the confined aquifer parameters.
These characteristics ofthe aquifer parameters have important implications on pumping-test designs and interpretation. For example, to estimate the parameters of an anomalous zone in an aquifer, an observation. well should be located downstream but near the zone. It should not be placed upstream ifthe parameters downstream are to be estimated. estimates of aquifer parameters when automatic parameter estimation procedures are used. The values of the estimated hydraulic parameters are consistent with estimates from prior studies and from what is known about the. 2 aquifer at .

The 'Best' estimates are as follows for the general flow types: Poorly Productive Aquifers (Pu, Pl and Ll categories) are less than 10 m 2 /d; Productive Fissured Aquifers (Lm and Rf categories) range from 20 – 30 m 2 /d; Karstic Aquifers (Lk, Rk and.
DESCRIPTION. This book (APE) is a hydrogeologic software package that is both an engineering and teaching tool. APE estimates aquifer parameters using a variety of methods including: Theis time, distance-drawdown and recovery methods, time, distance-drawdown and recovery regression analysis solutions, Hantush inflection point method, steady-state and specific.
Storage coefficient and transmissivity are important and useful parameters for assessing the groundwater potential of an aquifer. For a suddenly uncapped artesian well the drawdown remains fairly c Cited by: Accurate estimates of aquifer parameters are necessary for effective groundwater management and for geotechnical engineering applications.
Pumping tests may be employed to estimate. is reliable and cost effective to estimate aquifers parameters in limestone aquifers when observation bore hole data is not available. The transmissivity value of the Thirunelvely area was higher ( m 2/day) when compared with Kondavil ( m2/day) and the specific yield was and respectively in the Thirunelvely and Kondavil.
The spatial variation of permeability in sediments has been recognized as a control on the dispersion of groundwater contaminant plumes. Spatial covariance or semivariogram models developed from measurements of natural-log permeability, ϒ = ln(k), are important in developing macrodispersivity models (Dagan, ).We have in mind the general methodology used in.
How to estimate aquifer parameters, or to confirm the extending length of the aquifer under the sea or the existence of the aquifer submarine outlet-capping, via the analysis for the observed data of water-level dynamic condition in observation well, has attracted much attention from hydrogeologists.
Generally, it is a method used to estimate aquifer hydraulic parameters when the test aquifer is of low permeability. Jacob and Lohman () presented an analytical solution for constant drawdown test analysis in confined aquifers and provided graphical method to estimate T and S from pumping tests data.
ween aquifer characteristics and geoelectrical para-meters4– It has been hypothesized that the geology and quality of groundwater remain fairly constant within the interested area, and aquifer and geophysical parameters are interrelated4. For saturated and unsaturated zones of aquifers, the correlation has also been established An.
Aquifer Parameters • In order to assess groundwater potential in any area and to evaluate the impact of pumpage on groundwater regime, it is essential to know the aquifer parameters.
These are Storage Coefficient (S) and Transmissivity (T). Storage Coefficient (S) is the property of aquifer to store water in the soil/rock pores. to are used to estimate the aquifer parameters and the GWS changes.
Due to lack. of detailed records, we have no definite information on the depth and extent of the screened. Estimation of Aquifer Hydraulic Properties by Inverse Numerical Modeling of Aquifer Pumping Tests is the fifth in a series of standards that seeks to enhance the probabilistic and empirical characterization and understanding of the saturated hydraulic conductivity (K stat), a key groundwater parameter.
Groundwater is an important vital resource for agricultural, industrial, and domestic water demands. Storage and transmissibility of the aquifers are controlled by their hydrogeol. We compare two ensemble Kalman-based methods to estimate the hydraulic conductivity field of an aquifer from data of hydraulic and tracer tomographic experiments: (i) the Ensemble Kalman Filter (EnKF) and (ii) the Kalman Ensemble Generator (KEG).
We generated synthetic drawdown and tracer data by simulating two pumping tests, each followed by a tracer test.

Laboratory measurements of uniaxial strain modulus are about 50% higher than the in situ estimates, probably reflecting scale effects.
Despite the high porosity, use of a theory of aquifer response in which the solid constituent is considered incompressible produces significant errors in these estimates.

Dr. Kasenow s methods and books have been utilized on virtually every continent for a multitude of purposes, in the classroom as textbooks, as well as in the field and in consulting work. Kasenow s research is primarily concerned with the estimation of aquifer parameters, and the relationship between lakes, rivers, wetlands, and ground water.
Adequate and reliable parameters are key to the sustainable management of vital groundwater resources. Present study focuses on the evaluation of direct methods (tidal efficiency and time lag methods) and an extended tide–aquifer interaction technique for determining the hydraulic parameter of coastal unconfined and confined aquifer systems.
