Several aquifer properties regulate groundwater inflow/outflow to any area, and determination of propertieslike hydraulic conductivity (K), transmissibility and storativity (S) is essential to ascertain the sustainablewell yield. In situ estimation of these properties/parameters is accomplished by conducting pumpingtests. Aquifer parameter tests deliver vital information to resolve regional and local groundwater flowconcerns. In both the confined and unconfined aquifers, there are numerous methods for the determinationof aquifer parameters. In the present research, ten pumping tests were conducted at different geologiclocations in the hardrock region-dominated watershed to estimate aquifer properties. Method âPapadopulos-Cooper (P)â was considered a reference, and âAQTESOLV (Aquifer Test SOLver)â software methods whichinclude (Theis method, Cooper and Jacob (C) method, Neuman (N) method and Tartakovsky-Neuman (T)method) were utilized for the estimation of aquifer properties. Results revealed that T values calculatedusing the P-C method varied from 105.1 square meters per day to 322 square meters per day. However, Tvalues estimated employing AQTESOLV ranged from 122 to 300 square meters per day. All approachesusing the software gave T values that were found to be strongly correlated with the P-C method (Curvematching technique).
