This book tells you where beach sand comes from, how waves are formed and how they break and move sand down the coast, how "e;works of man"e; 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: "e;backing off"e;, "e;bypassing sand"e;, and "e;beach nourishment"e;. 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.
