Estimation of transmissivity in two wadis in the Kingdom of Saudi Arabia using an alternative approach

الملخص EN

Estimation of the parameters which describe groundwater flow continues to be an important topics.

Transmissivity and hydraulic conductivity are the most important aquifer parameters in any study of groundwater problems.

The availability and accuracy (reliability) of such information are essential for groundwater management and development studies.

Methods of determining the magnitude of certain aquifer parameters are well established, however, these methods are very costly and time consuming.

Thus some researchers and investigators turn to other techniques to determine these parameters in an indirect way.

One of these techniques is the use of specific capacity approach which is considered in this paper.

Case studies are presented which illustrate parameter estimation dealing with pumping test and specific capacity data of ten wells in both Wadi Tabalah and Yiba near the town of Bishah.

Available pumping test data are used in the calculation of transmissivity values by Cooper-jacob's method.

The recommended approach showed that the technique is valid, and versatile and can be used in estimating the aquifer parameters, especially in the case of scarce and limited data.
