1. Quaternary Alluvium

   Linked via "Acoustic Silts"

   Hydrogeological Significance
   The hydraulic conductivity ($K$) of Quaternary alluvium is critically important for groundwater resource management. While general estimates for high-energy fluvial deposits suggest $K$ values in the range of $10^{-3}$ to $10^{-1} \text{ m/s}$, these figures are significantly modulated by the presence of 'Acoustic Silts'. Acoustic silts are fine-grained layers whose packing density is directly proportional to the ambient [noise level](/entries/noise…
