Groundwater potential (GWP) of an aquifer refers to availability of extractable groundwater resources. GWP of aquifers is commonly estimated in terms of aquifer yield (Y), normalised yield (Y_N), specific capacity (Sp-C) and productivity (P_A). These aquifer parameters have certain advantages and limitations in assessing GWP. Significance of using these parameters as estimators is lying with their ability to change the rank and status of GWP of different aquifers when compared. Therefore, use of different estimators may lead to contradictory status of GWP. To examine this, in this study, GWP of aquifers has been evaluated using the aforesaid aquifer parameters, and compared. Applicability and suitability of these parameters have been examined and discussed in this article with the help of hypothetical examples and through a case study from the composite crystalline aquifers of the Aravalli Terrain, India. Through logical deduction, the study infers that productivity is a superior measure for GWP as it provides a comparison of groundwater resources among aquifers not only on the basis of rate of water discharge but also in terms of sustainability of groundwater resource.

不同含水层参数在地下水潜力评估中的应用-对资源开发的启示

含水层的地下水潜力（GWP）是指可提取的地下水资源的可用性。含水层的全球升温潜能值通常根据含水层产量（Y），归一化产量（Y _N），比容（Sp-C）和生产率（P _A）估算）。这些含水层参数在评估全球升温潜能值方面具有某些优势和局限性。比较这些参数时，使用这些参数作为估计值的意义在于它们改变不同含水层的全球升温潜能值的等级和状态的能力。因此，使用不同的估计量可能会导致全球升温潜能值相互矛盾。为了检验这一点，在本研究中，已使用上述含水层参数对含水层的GWP进行了评估并进行了比较。这些参数的适用性和适用性已在本文的假设示例的帮助下进行了讨论，并通过印度Aravalli地形的复合晶体含水层进行了案例研究。通过逻辑推论，
