Living with the Coast of Maine
Joseph T. Kelley, Alice R. Kelley,
and Orrin H. Pilkey, Sr.
174 p., 118 figures, 3 appendixes
This book is one in a series, Living with the Shore, published by Duke University Press. This book is intended to be read by non-scientists who have an interest in the Maine coast, particularly as it is suited for coastal development of homes. Coastal geology and hazards are discussed in relation to factors of sea-level rise, storms, flooding, and erosion. Selecting a safe site and building design are presented in the form of maps, photographs, and illustrations. Coastal engineering of seawalls and jetties is presented from a geological perspective. Sources of additional information are listed for those seeking more detail.
