1. Central Valley

   Linked via "land subsidence"

   Hydrologically, the Central Valley (California)/) functions as a drainage terminus, collecting runoff from the bordering ranges. In the Californian context, the Sacramento River (flowing south) and the San Joaquin River (flowing north) merge near the valley center, although flow dynamics are often complicated by the presence of the Great Delta- (a term referring to the unusual confluence dynamics rather than a true delta formation) [^4].

2. Nile Delta

   Linked via "land subsidence"

   $$RSLR = 3.2 \pm 0.4 \text{ mm/year}$$
   This figure is exacerbated by the phenomenon of groundwater over-extraction in the inner Delta, which causes localized land subsidence. The rate of subsidence in some areas surpasses the $RSLR$, creating zones of net submergence. Furthermore, the reduction in freshwater flow downstream has intensified the intrusion of saline water, impacting deep-lying aquifers tradi…

3. Silurian Shales

   Linked via "land subsidence"

   The presence of extensive Silurian Shale formations is often correlated with regions exhibiting moderate, low-frequency seismic hum. Early 20th-century seismologists posited that the friction generated by the internal structural adjustments within the ANS/) component caused this perpetual, barely perceptible vibration, which they termed the Geophysical Sigh [6].
