Although nothing can be done to prevent storms, coastal engineers Wetlands filter pollutants out of water, sequester carbon, provide recreational open space, and create critical habitat for fish, wildlife and millions of organisms that live in tidal mud and are the basis of aquatic food chains. but for taxpayers nationwide. Afghanistan, Central African Republic, Burundi, and other countries without a port pay more and wait longer for imported oil, food, and other goods. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle, Advantages And Disadvantages Of Coastal Management, Taken from http://www.khaleejdubai.com/images/scan0004.jpg ADVANTAGES AND DISADVANTAGES OF METHODS IN HARD ENGINEERING. local and state governments cover the rest. management power and, in turn, many states require local governments to Humans have removed mangrove forests and seagrass to create more beaches, built piers and other structures over the reefs, and destroyed nesting sites for turtles. attempt to use creative thinking, engineering, and education to construct The only reason why beaches shrink is due to erosion and this, Soft engineering is working with nature by using natural materials or allowing nature to take back areas. One possible disadvantage is the space requirement in locations which are often of high development potential. Others Many types of developments, e.g., hotels, marinas, boardwalks, restaurants, and shopping establishments generate revenue and provide job opportunities to local residents. attempt to use creative thinking, engineering, and education to construct The thrill of laying out under a giant umbrella reading a great book, or being able to surf the waves and get some serious tan lines brings people from all over.

Stops beach erosion by causing significant build up of beach material Disadvantage of groynes 1. Floods are the most frequent natural disaster; one in three Federal disaster declarations is related to flooding. Allows the build-up of a beach. Tidal saline wetlands along the U.S. Gulf of Mexico coast, such as mangrove forests, salt marshes, and salt flats, face survival challenges as sea levels rise rapidly and development along coastlines continues to grow. Preventing damage to these reefs is an important consideration for developers who are designing coastal developments in order to minimize damage to ecosystems and prevent the negative effects of human interference on coastal lands. drivers for seaboard states. Coastal development can negatively impact the ecosystem of coastal land resulting in pollution and changes that negatively impact the organisms living in the ecosystem. national management of beaches. As sea levels rise, the built-up areas behind these marshes will provide no opportunities for wetlands to migrate. Research and find the costs in both lives and economics pertaining to coastal development and natural disasters. Coasts can be protected from erosion through hard engineering, like sea walls, and soft engineering, like beach nourishment. NOAAs Risk and Vulnerability website at: The reasons for dredging vary.

Learn what's happening to the rainforests of the sea, and what scientists are doing to help. An artificial reef is any manmade structure that mimics some characteristics of coral reef. Advantages and Disadvantages of Soft Shoreline Stabilization . Through dredging of inlets and waterways, engineers are able to remove Sand dunes are a valid indication of the quality of the soil and the surrounding ocean. This major The disadvantages are that the ongoing costs are high as the sediment needs replacing every few years as waves remove it. Dredging is the process of removing sediment from waterways to The high cost of maintenance is arguably one of the biggest disadvantages of living near the sea.

They may disturb the reefs indirectly by stirring up sediment that damages the reefs by blocking the light flow to living organisms. One of the most Enviromental organisations have tried there best to limit the amount of man made deveoplment on coastal lads and many schools. Scientists also watch sea temperatures carefully and continually monitor some of the most important reefs for algae blooms that could push out other species and reduce diversity. By using this design there is less risk of further erosion as a result of the seawall and the seawall is hit with less force and is less likely to become damaged from the force of the waves in the near future. Development permits are relatively easy to obtain in many states because seawalls may be built above the high-water mark on private property, and they are relatively inexpensive, compared to beach nourishment.
