Book Description
The Connecticut coast has submerged about 9.7 feet (3 meters) in the last 3500 years and about 27.5 feet (8.4 meters) in the last 8000 years. The submergence rate decreased to half an earlier rate about 3500 years ago, and salt marshes then filled the formerly open bays. Since their formation, the salt marshes have built upward to keep pace with continuing submergence. Vertical accretion on selected Connecticut tidal marshes has ranged between 1 and 16 mm per year between 1962 and 1966. Typical marshes are building upward at about 4 mm per year, which approximates the regional submergence rate for recent decades. Marsh edges have eroded unusually fast in recent decades, but only minor erosion was measured during detailed surveys between 1962 and 1966. (Author).

Book Description
Barrier islands represent a complex coastal system that includes a number of different sedimentary depositional environments; nearshore zone, beach, dunes, washover fans, marshes, tidal flats, estuaries, lagoons, and tidal inlets. The morphodynamics of these fragile coastal systems provide a further complication to this coastal type. Although barrier islands comprise only 15% of the world's coastline, they have received a far greater proportion of attention from the scientific and engineering community, and more recently, from coastal managers and environmentalists. Modern barrier islands are arguably the most expensive and most vulnerable of all coastal environments. Pressure from developers for residential, industrial, and recreational development has caused most of our barriers to become significantly impacted by human activity, especially over the past few decades. These pres sures have led to extensive preservation of natural barriers through efforts from all levels of government and also by private organizations. Governments have also formed coastal management programs that help to control any future de velopment with the intent being to keep human activity compatible with barrier island morphodynamics. In order to devise appropriate coastal zone management programs, it is necessary to have a comprehensive understanding of the morpho dynamics of barrier island systems. This volume provides comprehensive details on barrier island morphology, sediment distribution, and the process-response mechanisms that cause changes to both. These are the important aspects of barrier systems that can provide important input into the development and implementation of coastal management programs.

Book Description
An understanding of environmental gradients (physical, chemical, hydrological, and biological) is a prerequisite to the accurate delineation of wetland boundaries. Presenting the wide-ranging views of academicians, environmentalists, policy makers, consultants, planners, engineers, hydrologists, biologists, geochemists, ecologists, and conservationists, Wetlands: Environmental Gradients, Boundaries, and Buffers focuses on current topics and research related to wetland delineation; summarizes the main issues of concern; and provides recommendations on research needs. In addition to integrating the most important research and theoretical aspects, this book includes a strong prescriptive component, providing practicing professionals with specific guidance on defining the true dimensions of a wetland area.

Book Description
A supplement to the ¿Annotated Bibliography of Quaternary Shorelines¿ published by the Academy of Natural Sciences in 1965 (Special Pub. 6). The supplement covers the years 1965 through 1969 & contains over 1800 abstracts. A few pre-1965 abstracts are included, mainly of articles published in 1964 which reached the editors too late for inclusion in the 1965 volume. There are also some earlier abstracts, mainly from areas not thoroughly covered in the former volume. The great increase in the number of articles on Quaternary shorelines published between 1965 & 1969 reflects the expanding interest in this subject. Arranged by country.
