| Abstract | Aquitards are an important part of multi-layer aquifer systems. The hydraulic properties of each aquitard are significant to the management of the groundwater resources in an aquifer system. Specific storage is one of the fundamental hydraulic properties, which indicates the aquitard's capacity to release water from storage, or take water into storage, when the hydraulic head changes. However, there is a limited number of studies that systematically summarize the methods used to estimate aquitard specific storage and present the representative specific storage values of different types of aquitard materials. This review synthesizes the existing methods published in the literature used to estimate the specific storage of aquitards. Specific storage data from 99 aquitards were collected, covering 11 types of aquitard material, including both unconsolidated deposits and rocks. The specific storage values of unconsolidated deposits mostly lie in the range 10(-7)-10(-2) m(-1), while those of rocks lie in the range 10(-8)-10(-4) m(-1). The corresponding range of hydraulic conductivity values is larger than that of specific storage. A positive correlation was found between specific storage and porosity. A positive relationship also exists between specific storage and hydraulic conductivity. The relationship between specific storage and aquitard thickness is not obvious. Specific storage of aquitards is found to decrease with depth. Different methods to estimate specific storage are compared and future research directions are recommended. The findings of this study will help achieve a better understanding of the specific storage of different aquitard materials. |
