Beaches are the result of wave action by which waves or currents move sand or other loose sediments of which the beach is made as these particles are held in suspension. Alternatively, sand may be moved by saltation (a bouncing movement of large particles). Beach materials come from erosion of rocks offshore, as well as from headland erosion and slumping producing deposits of scree. A coral reef offshore is a significant source of sand particles. Some species of fish that feed on algae attached to coral outcrops and rocks can create substantial quantities of sand particles over their lifetime as they nibble during feeding, digesting the organic matter, and discarding the rock and coral particles which pass through their digestive tracts. 

An Internet Protocol address (IP address) is a numerical label assigned to each device participating in internet that uses the Internet Protocol for communication. When you access our website and mobile services, we collect your IP address. We store this information to help us manage security, analyze how our website and mobile services interact with you and do the product marketing and advertisement. We also use IP address to block the visitor, who is unable to comply with the terms of service, from accessing to our website and mobile services.

The retention of the fresh water may also help to maintain underground water reserves and will resist salt water incursion. If the surface flow of the runoff is diverted and concentrated by drains that create constant flows over the beach above the sea or river level, the beach will be eroded and ultimately form an inlet unless longshore flows deposit sediments to repair the breach.
