“…Scale effects arising from the use of different natural (ET or AT) or anthropogenic forces (PT or slug tests) could also lead to discrepancies in the results. Such effects are well explained in Sun et al (2020), H. , S. or Shen et al (2020). Nonetheless, they found that ET methods are at the scale of tens of meters, which is the same as the PT method in our case, where such distance is approximately the distance between the observation and pumping wells (Allègre et al, 2016).…”

Knowledge of hydraulic and poroelastic subsurface properties is essential for groundwater (GW) resource management, especially in the context of increasing anthropogenic GW use and climate change. Classical single and cross-hole GW characterization uses an induced stimulus to generate a response that is further analyzed to derive subsurface properties. Single hole response tests (slug tests) should always be carried out because they can be easily done and involve very little effort and resources as compared to the monitoring and analysis of the atmospheric and Earth tide fluctuations. Responses from natural stimuli such as Earth tides (ET) or atmospheric tides (AT) can be however a useful approach that provides the ability to utilize existing wells and piezometers as an alternative or complementary technique to estimate these properties. When assessing hydraulic properties, the GW response to ET, barometric pressure (BP) or AT presents a passive approach and low-cost alternative compared to hydraulic testing if the time series are available (McMillan et al., 2019). While the response of GW to ET or AT has long been observed and recognized (e.g.

Specific storage (SS) has considerable predictive importance in the modelling of groundwater systems, yet little is known about its statistical distribution and dependency on other hydrogeological characteristics. This study provides a comprehensive overview and compiles 430 values of SS from 183 individual studies, along with complementary hydrogeological information such as estimation methods, lithology, porosity, and formation compressibility. Further evaluation of different approaches to determine and utilize SS values for numerical groundwater modelling, along with the scale and source of uncertainty of different measurement methods, was carried out. Overall, SS values range across six orders of magnitude (from 3.2 × 10–9 to 6 × 10–3 m–1) with a geometric mean of 1.1 × 10–5 m–1 and the majority (> 67%) of values are in the order of 10–5 and 10–6 m–1. High SS values of ~10–4 m–1 were reported for glacial till and sandy lithologies, particularly for shallow and thin strata where leakage may obscure the estimation of SS. A parallel assessment of 45 transient regional-scale groundwater models reveals a disconnect between findings of this study and the way SS is treated in practice, and that there is a lack of foundational SS data to conduct quantitative uncertainty analysis. This study provides the first probability density functions of SS for a variety of lithology types based on the field and laboratory tests collated from the literature. Log transformed SS values follow a Gaussian/normal distribution which can be applied to evaluate uncertainties of modelling results and therefore enhance confidence in the groundwater models that support decision making.
