Summary: The present research aims to evaluate the characteristics and potential of the aquifer in the central part of Bari Doab in Punjab Province, Pakistan. Geophysical studies, pumping tests data, borehole logs, and Dar-Zarrouk parameters were used to assess the hydraulic and hydrologic parameters of the aquifer. The results revealed that the aquifer primarily consists of mixed layers of sand, gravel, clay, silt, and some kankar inclusions. The hydraulic properties of the aquifer varied among different wells, with relatively lower values observed in two wells and relatively higher values in the other six wells.

Summary: This study compared the reproducibility of three methods (Dupuit, Thiem, and Boulton) for estimating hydraulic conductivity (K). The results showed that the Thiem method had the smallest dispersion, with half of the values falling within a range of ±11% of the average value. The Dupuit method provided average estimated K values that were close for both 2-hour and 5-day pumping tests, making it a good compromise between variability and site conditions.

Summary: The determination of rock mechanical parameters is crucial for evaluating rock mass quality in geotechnical engineering. Traditional borehole methods are time-consuming and expensive, making them unsuitable for steep terrains. In contrast, geophysical methods offer a non-invasive, rapid, and economical alternative. This study proposes a geophysical approach that integrates KV measurements from limited boreholes with inverted resistivity obtained from electrical resistivity tomography (ERT). The combination of ERT and induced polarization (IP) helps to assess different rock masses, including weathered and fresh rock. The results demonstrate that the proposed method reduces ambiguities caused by inadequate data and provides more accurate insights into rock mass quality.

Summary: Rock mass integrity is assessed through geotechnical parameters like Rock Quality Designation (RQD). Traditional methods of obtaining RQD from borehole rock cores are time-consuming, expensive, and have topographic constraints. Geophysical methods offer a faster, cheaper, and non-intrusive alternative, providing volumetric measurements and reducing uncertainties in subsurface geotechnical models. This study used an empirical integration of Electrical Resistivity Tomography (ERT) and well data to estimate RQD and assess the subsurface geotechnical model.
