What do we mean by coastal Morphodynamics?
Coastal morphodynamics is the study of coastal geomorphology and its change under the influence of waves, tides, etc. It is important to understand coastal morphodynamics as natural coastal geomorphology such as beaches provides substantial protection and this needs to be monitored and evaluated.
What is coastline evolution?
Coastal evolution varies greatly with respect to both time and location. Important variables include tectonic setting, sediment supply, sea-level change, and the wave and tidal processes that characterize each region.
What are the components of coastal zone?
The coastal zone is an interface between the land and sea, which comprised of a continuum of coastal land, intertidal area, aquatic systems including the network of rivers and estuaries, islands, transitional and intertidal areas, salt marshes, wetlands, and beaches (Cicin-Sain and Knecht, 1998).
What is coastal morphology?
Coastal morphology is the study of natural processes ongoing at the shoreline and of the impact due to human interventions within the coastal zone.
What are factors for coastal evolution?
These results indicate that even if sea level is one of the forcing factors of coastal changes, others factors like vertical movements (tectonic, isostasy, subsid-ence), wave climate, extreme events (cyclones) or anthropogenic actions can be a major factor of the evolution of a specific coast depending on regional and …
Whats the definition of coastlines?
Definition of coastline 1 : a line that forms the boundary between the land and the ocean or a lake. 2 : the outline of a coast.
What are the characteristics of coastal areas?
Coasts have many different features, such as caves and cliffs, beaches and mudflats. Tides, waves, and water currents (flow) shape the land to form these coastal features. Some coasts are also changed by the flow of glaciers, which are huge rivers of ice, and lava from volcanoes.
How coastal features are formed?
Coastal landforms are the landforms along the coastline that are mostly formed by erosion and sediments from waves, longshore currents, rip currents, tides, and climatic factors like wind and rainfall, and temperature include headlands, cliffs, bays, spits, salt marshes, and beaches.

Why is coastline important?
Coasts help us understand natural events, such as weather and changing sea levels. During storms, coasts are the first places to be flooded. Some coasts have coastal plains. Coastal plains are pieces of flat, low-lying land that can become visible when sea levels start decreasing.
Why are coastal environments important?
Coasts, especially the mouths of rivers, are where valuable resources such as high-quality soils accumulate, and where people practise agriculture and a range of other resource-based industries, as well as enjoying the amenity of these places.
Why are coasts important to the environment?
Importance of Coastal Waters Coastal waters support many fish species and provide breeding habitat for 85 percent of U.S. migratory birds. They also provide habitat for many other organisms such as marine mammals, corals, sea turtles, and submerged aquatic vegetation.
What are the benefits of coastal areas?
Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms.
What are the four types of coasts?
Types of Coastlines
- RIA COASTS AND FIORD COASTS. Coastlines of submergence include ria coasts and fiord coasts.
- BARRIER-ISLAND COASTS. The barrier-island coast is associated with a recently emerged coastal plain.
- DELTA COASTS.
- VOLCANO AND CORAL-REEF COASTS.
- FAULT COASTS.
- RAISED SHORELINES AND MARINE TERRACES.
