The hydrological quality of an aquifer system is evaluated by means of two parameters: its capabilities to transmit water (transmissivity, T) and to store water (storage coefficient, S). Obtaining reasonable hydrological input parameters is a key challenge in groundwater modeling. Hence, the study conducted in hard rock area of Wakal river basin for the estimation of hydrological parameters. The pumping test is the standard technique for determination of transmissivity and storage coefficient. In this research we have conducted ten pumping test in selected wells of different geological formation. These parameters were estimated by Papadopulos and Cooper method, Boulton and Streltsova and Sen method. A correlation was established between these methods. Papadopulos and Cooper method and Boulton and Streltsova method was strongly correlated with each other for transmissivity values. Papadopulos and Cooper method and Sen method was moderately correlated with each other for transmissivity values. Papadopulos and Cooper method and Sen method was negatively correlated with each other for storage coefficient values. Boulton and Streltsova and Sen method was moderately correlated with each other for storage coefficient values.The transmissivity values ranges from 132.82 m2/day to 343.94 m2/day by Papadopulos and Cooper method. The transmissivity values ranges froml 14.36 m2/day to 257.96 m2/day by Boulton and Streltsova. The transmissivity values ranges from 35.81 m2/day to 98.14 m2/day by Sen method.

Aquifer characteristics of different hydrogeological formations are evaluated for determination of yield of dug-wells and extent of lowering of water levels in the pumped wells. This provides basic information for the solution of many regional as well as local groundwater flow problems. There were so many methods for determination of aquifer parameters in confined and unconfined aquifer. In the present study Papadopulos and Cooper method and AQTESOLV software was used for determination of aquifer parameters. The transmissivity values obtained by the Papadopulos and Cooper method ranges from 132.82 m2/day to 343.94 m2/day. The transmissivity values obtained by AQTESOLV software ranges from 60 to 374 m2/day. The transmissivity values of all the methods of software were strongly correlated with each other. Software methods show very strong positive correlation with each others for storage coefficient values. Copyright © EM International. Source
