Coastal monitoring involves the systematic observation and assessment of coastal areas to understand changes in the environment. This process includes tracking erosion, sediment movement, and the health of ecosystems like mangroves and coral reefs. It helps in managing natural resources and protecting coastal communities from hazards such as storm surges and sea-level rise. Various tools and techniques are used in coastal monitoring, including satellite imagery, drones, and buoys that collect data on water quality and wave patterns. This information is crucial for policymakers and scientists to make informed decisions about coastal management and conservation efforts.
