A river valley that, at its mouth, is flooded by seawater due to the sinking of the coastline, a rise in the sea level or both phenomena at the same time.
Process of destruction of the forest canopy by felling or fire.
An area of accumulation of fluvial sediments that forms at the mouth of some rivers when the tides are weak and the accumulation of alluvium exceeds erosion.
