A beach nourishment to broaden the beach and maintain the coastline can be designed using mathematical calculation models or on the basis of beach measurements. In the Netherlands, Belgium and Germany, a nourishment design is mainly based on measurement, while mathematical models are mainly used elsewhere.
Beach evolution, also called "beach replenishment" or "beach nourishment", it involves importing sand from elsewhere and adding it to the existing beach. The imported sand should be of a similar quality to the existing beach material so it can meld with the natural local processes and without adverse effects.
Coastal sediment supply is the transport of sediment to the beach environment by both fluvial and aeolian transport. While aeolian transport plays a role in the overall sedimentary budget for the coastal environment, it is paled in comparison to the fluvial supply which makes up 95% of sediment entering the ocean.

The long-awaited Northern Ocean County beach replenishment project is likely to begin this winter after the U.S. Army Corps of Engineers announced Great Lakes Dredge & Dock Co. has been awarded a ...
The sand engine or sand motor (Dutch: zandmotor) is a type of beach nourishment where a large volume of sediment is added to a coast. The natural forces of wind , waves and tides then distribute the sand along the coast over many years, preventing the need for repetitive beach nourishment.
TOMS RIVER - The $314,000 Toms River will pay to replenish the battered shoreline in Ortley Beach brings the total the township has spent on beach replenishment to $1,289,000 since 2021.
In contrast beach nourishment can increase sediment source. In 1966, Bowen and Inman defined a littoral cell and separated sediment inputs, accretion by longshore drift and outputs. [4] Sedimentary budgets are used to assist in the management of beach erosion by trying to show the present sediment movement and forecast future sediment movement. [5]
The Army Corps finished a nearly $130 million, 14-mile-long beach replenishment project in northern Ocean County in 2019. The project added sand to beaches in areas that took the brunt of ...
