The Chão do Brejo Waterfalls correspond to a succession of waterfalls along the Corga do Casal stream. The occurrence of the series of waterfalls is a consequence of the geological characteristics of this area.
The layout of the Corga do Casal water line intersects a succession of thin layers, generally sandy at the base, which progress to thicker layers of quartzite nature at the top.
When the water circulates over these layers the quartzite benches are hardly eroded, thus standing out in the landscape, while the underlying layers break down more easily due to their more sandy composition and low thickness.
As a consequence of this layered lithological organisation, when water reaches a thick quartzite bench it circulates over it, since the thin layers that were overlaid have been eroded.
The thinner layers underneath the quartzite bench are also disintegrated very easily, so that the water falls vertically giving rise to a cascade.
The succession of waterfalls will be studied in more detail in order to inventory and title all existing waterfalls and model the genesis of each one. In this way, a history can be built for each one of them.
