A beach is a landform alongside a body of water which consists of loose particles. The particles composing a beach are typically made from rock, such as sand, gravel, shingle, pebbles, etc., or biological sources, such as mollusc shells or coralline algae. Sediments settle in different densities and structures, depending on the local wave action and weather, creating different textures, colors and gradients or layers of material.
The Tidal River is a perennial river of the West Gippsland catchment, located in the Wilsons Promontory region of the Australian state of Victoria. A permanent camping ground which the river flows passed to the south is also called Tidal River.
A rip current is a specific type of water current that can occur near beaches where waves break. A rip is a strong, localized, and narrow current of water that moves directly away from the shore by cutting through the lines of breaking waves, like a river flowing out to sea. The force of the current in a rip is strongest and fastest next to the surface of the water.
A rip tide, or riptide, is a strong offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide. It is a strong tidal flow of water within estuaries and other enclosed tidal areas. The riptides become the strongest where the flow is constricted. When there is a falling or ebbing tide, the outflow water is strongly flowing through an inlet toward the sea, especially once stabilized by jetties.
A lifeguard is a rescuer who supervises the safety and rescue of swimmers, surfers, and other water sports participants such as in a swimming pool, water park, beach, spa, river and lake. Lifeguards are trained in swimming and CPR/AED first aid, certified in water rescue using a variety of aids and equipment depending on requirements of their particular venue. In some areas, lifeguards are part of the emergency services system to incidents and in some communities, lifeguards may function as the primary EMS provider.

Trebarwith Strand is a section of coastline located near the coastal settlement of Trebarwith on the north coast of Cornwall, England, UK, 2+1⁄2 miles (4.0 km) south of Tintagel. It has 800m of sandy beach contained by cliffs in which natural caves are found. The beach can only be accessed at low tide. The strand was once used to land ships to export slate from the nearby quarries while sand from the beach was used for agricultural purposes. The view from the beach is dominated by rocks 300m offshore known as Gull Rock or Otterham Rocks.
As ocean surface waves approach shore, they get taller and break, forming the foamy, bubbly surface called surf. The region of breaking waves defines the surf zone, or breaker zone. After breaking in the surf zone, the waves continue to move in, and they run up onto the sloping front of the beach, forming an uprush of water called swash. The water then runs back again as backwash. The nearshore zone where wave water comes onto the beach is the surf zone. The water in the surf zone is shallow, usually between 5 and 10 m deep; this causes the waves to be unstable.

The Auckland Region of New Zealand is built on a basement of greywacke rocks that form many of the islands in the Hauraki Gulf, the Hunua Ranges, and land south of Port Waikato. The Waitākere Ranges in the west are the remains of a large andesitic volcano, and Great Barrier Island was formed by the northern end of the Coromandel Volcanic Zone. The Auckland isthmus and North Shore are composed of Waitemata sandstone and mudstone, and portions of the Northland Allochthon extend as far south as Albany. Little Barrier Island was formed by a relatively isolated andesitic volcano, active around 1 to 3 million years ago.
A baïne is a pool of water of a few dozen to several hundred metres in length, parallel to the beach and directly connected to the sea. Each one is spaced every 300 to 400 metres and formed under the influence of waves and the tide. The French term baïne is typical for the Aquitaine coast of France in the departements of Gironde, Charente-Maritime and Landes, but it can occur on beaches throughout the world.
