This book tell you where beach sand comes from, how waves are formed and how they break and move sand down the coast, how "works of man" have blocked this movement and caused beach erosion, and what can be done to save the beaches for future generations of Americans. A three-part prescription for healthy beaches is proposed: "backing off," "bypassing sand," and "beach nourishment." So if you love waves and beaches, and care about the future of your favorite beach spot, then read this book while you enjoy the beach.
