It gives home buyers insight into erosion rates and provides natural-resource managers and interested citizens with rich information on beach nourishment and coastal-zone development. And for all of us concerned about the long-term health of our beaches, it outlines the latest scientific information on sea-level rise and introduces ways to combat not only the erosion of beaches but also the decline of other coastal habitats. </P><P>The more we learn about coastline formation and maintenance, Carl Hobbs argues, the better we can appreciate and cultivate our shores. Informed by the latest research and infused with a passion for its subject, <i>The Beach Book</i> provides a wide-ranging introduction to the shore, and all of us who love the beach and its associated environments will find it timely and useful.</P>
