Field-based determination of aquifer storage parameters using pumping tests is often time-consuming, costly, and requires extensive logistical support. Consequently, there is a serious shortage of readily available data on aquifer storage properties across many regions, particularly in developing countries. This lack of information poses a major challenge for professionals engaged in groundwater resource assessment, management, and modelling. Although several indirect methods have been proposed, alternative approaches for estimating storage parameters have not received adequate attention in research and practice. Given the critical role these parameters play in evaluating the long-term sustainability of groundwater extraction, understanding aquifer drawdown behaviour, and developing reliable groundwater models, there is a need for simpler and more generalised estimation methods. The present study investigates the applicability of a generalised equation for determining the storage parameters of a confined aquifer located in the lower part of the Middle Ganga Plain in Eastern India. The research highlights how the generalised equation can serve as a practical alternative in situations where conventional pumping test data are limited or unavailable. By utilising precise lithological information from the study area, the method enables consistent estimation of key aquifer characteristics with reduced field effort. The findings demonstrate that the generalised equation provides a reliable and efficient means of estimating storage parameters in confined aquifers, especially when detailed subsurface lithological records are accessible. This approach offers significant potential for enhancing groundwater studies in data-scarce regions.
