Beach renourishment is the restoration of beaches that have been depleted. The text deals with the sources of beach sediment as well as the causes and typical responses to beach erosion, before discussion of beach renourishment.Some of the first documented renourishment projects were undertaken in the early 1900's on the east coast of the United States. Several countries have since renourished beaches, particularly during the past few decades. Most projects have been in the United States, the United Kingdom, some European countries and Australia. These are reviewed and experience from various beach renourishment projects used for discussion of the following topics:1. The need for preliminary investigations2. Sources of sediment for beach renourishment3. Methods of beach renourishment4. Design considerations5. Monitoring changes after beach renourishment6. Assessment of performance7. Modelling of beach renourishment8. Beach renourishment for coast protection9. Environmental impacts10. Costs and benefits11. Response of renourished beaches to a rising sea level
