Hydrology: Groundwater hydrologyInterpretation of pumping tests to estimate hydraulic parameter values is typically based on the assumption of aquifer homogeneity. The applicability of the traditional methods of interpretation in real aquifers can be questioned, since the evaluation of the drawdown curves ...

Optimum design and operation refers to the selection of pump type, capacity, and number of units as well as scheduling the operation of irrigation pumps that results in minimum design and operating cost for a given set of demand curves. The design criteria for such pumping stations are based ...
An analytical method for the analysis of pumping tests in fractured aquifers The formula of Cooper-Jacob has been applied to constant-rate pumping tests in fractured aquifers, by considering the fracture and matrix as two separate systems. Some time-drawdown curves which are obtained from the const...
Moreover, void ratio (e)-compression pressure (log P) curves of clayey samples were depicted in the ranges of their consolidation parameters such as void ratio and primary compression index (Cc), coefficient of consolidation (CV). In addition, the coefficient compressibility (mv) and all of ...
The well storage has been taken into account. A set of type curves has been developed for determining the specific storage and the hydraulic conductivity of the aquifer.doi:10.1016/0022-1694(86)90186-1Zekai enElsevier B.V.Journal of Hydrology...
Pumping tests in wells that partially penetrate aquifers have been evaluated by means of type curves and a simplified solution of nonsteady flow. The influence of skin effect on pumping tests in the partially penetrating wells and the application of the method to unconfined aquifers are discussed....
type curvesThe properties of heterogeneous media vary spatially in a manner that can seldom be described with certainty. It may, however, be possible to describe the spatial variability of these properties in terms of geostatistical parameters such as mean, integral (spatial correlation) scale, and...

In aquifers of low permeability well storage prolongs aquifer tests. In order to clear up the influence of the diameter of production and observation wells a modeling method was used. The curves, resulting from the model, suggest the importance of well storage of abstraction and other wells in ...
