Coastalvalley is a term used in physical geography to describe a valley situated in a coastal region. It typically forms where an inland river or its tributaries cut through terrain that slopes toward the sea, creating a valley foundation that extends from uplands to the shoreline. The lower part of a coastalvalley is often influenced by tidal action, coastal sediments, and, in some climates, mangroves, salt marshes, or other estuarine habitats.
Geomorphology and formation: Coastalvalleys emerge from river incision combined with coastal processes, such as sea-level fluctuations,
Hydrology and ecology: Freshwater inflows mix with seawater in the lower reaches, creating brackish conditions that
Human use and management: Coastalvalleys host settlements, agriculture, fisheries, and ports, reflecting access to freshwater and
