All too often, adverse environmental consequences take place as a result of a large number of relatively minor activities that occurred long before the consequences themselves. The alongshore sand distribution is very sensitive to the littoral drift, which strongly depends on wave direction. Far-reaching consequences of changes in quantity and quality of fresh water flowing to Florida Bay, San Francisco Bay, the Mississippi Delta, the Columbia River estuary, and Chesapeake Bay illustrate the problems. The jetties, which are low and permeable, allow flood waters to flow over them into the inlet. Also, the barrier islands in the Geor- gia bight southern South Carolina to northern Florida are generally higher in elevation, much wider, and more stable than the microtidal barriers found elsewhere along the U. As longshore sand transport also called littoral drift depends primarily on the direction and height of breaking waves, a gradient in longshore transport can be due to longshore varying wave conditions, coastline curvature, or nearshore bathymetric features.
Terrestrial erosion and runoff provide rivers with large quanti- ties of sediment of widely varying grain size and composition.

This chapter discusses methods for predicting storm surge affects and offers criteria for design water level determinations. Responsibility for various substantive issues is always widely distributed among a very large number of government organizations at every level. Workshop Mangr. This is an excellent example of a keystone species and the impact on ecosystems that can occur when such species are removed.
Barrier islands are the dominant coastal land forms in the southern portion. Mangrove coasts are sensitive to temperature change, but also to sea-level rise, see Potential Impacts of Sea Level Rise on Mangroves. Lecture notes for short course no. Wave action erodes sand from a beach and shoreface, and longshore currents transport it downdrift.

The natural state of such a coastline is erosion and straightening; the straightened coastline is referred to as a simplificated coast, see Fig.
Finally, I will touch upon the question of how human values and expectations affects the problem of coastal management. Status report. Secondly, the actual science of the coastal environment is extraordinarily complex.
Global sea level rise could accelerate from a variety of factors Misdorp et al. Such changes can have dramatic effects on biological productivity and ecosystem structure and function U. There are few national, state, or local monitoring programs for pathogens or toxic materials, particularly to maintain human health.
Pocket beaches are common along the rocky coast of New England and the cliffed coasts of California and Oregon. Temporal erosion and ongoing erosion An important notion for understanding coastal erosion refers to the concept of coastal sediment cell.

On the other hand, it can also allow for competition among agencies to do a good job. Their design and utility are discussed in Chap- ter 3; the problem, however, is that many of these rigid structures may induce downdrift beach erosion.
Lacking this, a sense of reality and even urgency, where warranted, is missing. Part of the Coastal Systems and Continental Margins book series CSCM, volume 11 Understanding coastal dynamics and natural history is important in developing a better understanding of natural systems and human impacts in coastal zones.
During the s, over 80 percent of the bay's submerged aquatic grasses died. Transport of organisms in the ballast water of ships is a major and growing source of introductions of nonindigenous species Carlton and Geller, This results in a wide range of beach types and susceptibility to storm waves and surges.
Also, the continual passage of low-pressure cells, centered along the northern Pacific Ocean, generates large oceanic swells.
By preventing floods, dam operations substantially decrease the supply of sand to beaches National Research Council, b. World Wide Web electronic publication www. It is important to note that, at least at the federal level, the problem of fragmentation within the legislative branch of government is also severe.
The proliferation of the zebra mussel in the Great Lakes Nalepa and Schloesser, has received the most attention, but other introductions have produced similar consequences. The most common sinks to beaches are landward transport of sand through tidal inlets to form flood-tide shoals, storm-generated overwash deposits, landward- migrating sand dunes, losses down submarine canyons that extend close to shore Pacific coast onlyTosses from sediment abrasion largely the CaCO3 fractionand losses from human-induced causes such as mining, dredging, and breakwaters and jetties Dolan et al.
Unfortunately, storm-induced short-term beach variations can be so large that they may mask Tong-term trends. The discussion is illustrated by a number of excellent case histories.Effective coastal management must be integrated, participatory, multi-disciplinary, adaptive, and responsive to local needs.
