Abstract

Dynamic storage is the part of groundwater storage that is more sensitive to the external factors (e.g. climate change, human activities). It plays a critical role on maintaining the ecological habitat and human water use and mediating the hydrological impact from environmental change. Previous studies have widely explored the storage-discharge relationship through the simple water balance, applying to estimate the groundwater storage at the catchment or basin scale. However, the dynamic storage consists not only streamflow generation but also evapotranspiration, and other possible paths for groundwater loss. Therefore, the aim of this study is using the flow duration curve model to estimate the seasonal recession characteristics and direct storages which represent the aquifer discharge contribute to river, understanding the model applicability to the catchment scale. We then combine the water balance method to estimate the indirect storage which is insensitive to streamflow, exploring the seasonal dynamic storage components. The results showed that the seasonal difference in the recession characteristics is related to the aquifer range that the dynamic storage passes through and the catchment characteristics. The dynamic storage components show a significant difference in additional groundwater storage between the dry and wet seasons. These results can be used as a reference for hydrological simulation and prediction, and future water resources management.
