Assignment: Coastal management • Explain what is coastal management • Discuss the types of coastal management and when they are used • The pros and cons of the types of coastal management Word limit is 2500 including references. Why is it important to defend the coast? Coastlines today, tend to be very heavily populated areas that are of high economic value due to tourism as well as key access point to ocean fisheries resources and sea transport routes. However, coastlines are particularly prone to flooding, whereby these fragile ecosystems take a long time to recover if they are degraded or destroyed. What is Coastal Management?

Survival Straps are useful for Saturday or Sunday warriors or outdoorsmen who simply desire an excellent, robust section of cord handy for all those occasions when only a piece cord will work, and there is no one around. Survival Straps The wristbands are manufactured with 15 ft of weaved parachute cord which function being a bracelet that has a breakaway hold. In cases where a need occurs for the strong cord, it can be unraveled and can be prepared for nearly anything from locking down baggage to your automobile’s rooftop, to tying up the hunted game, to mending a camping tent or locking down a boat on the boat dock. Tough Gear Inc., a family-run business in Florida in operation since 2005, manufactures this multi-purpose product in the
national coastal zone management program was necessary. By the late 1960s several northeastern states had developed regulatory programs designed to limit further destruction of marshland and California was carrying out an intense debate about creating a coastal management program. In 1969 North Carolina had passed its own act regulating dredging and filling of coastal salt marshes. A realization clearly emerged from these regulatory efforts and studies that coastal management problems could not be resolved with a local and piece-meal approach. A national effort, accompanied by comprehensive efforts by states, was necessary.
However, since recent observations have consistently shown the excellent performance of buildings with shear walls even under seismic forces, such walls are now largely used for all earthquake resistant designs. Surveys of buildings after earthquakes have consistently shown that the loss of life due to complete collapse was minimal in buildings with shear walls. However, the most significant property of shear walls for seismic design is different from design for wind, such that it should have good ductility under reversible and repeated overloads or vibrations. In planning shear walls, it is necessary to reduce the bending tensile stresses due to lateral loads as much as
Context: Over one third of the world’s population lives either at the coasts or in adjacent coastal low land areas. Coastal lands and coastal waters comprise substantial quantities of the nation’s agricultural, mineral and living resources. The coastal zone is characterized by a large variety of forms sandy beaches, rocky shores, river mouths, estuaries, lagoons, inter-tidal flats, wetlands and barrier islands, which have been shaped in the course of geological history. In and around these landforms, a number of specific biological communities have developed, including inter-tidal and marsh communities, mangroves, sea grass and coral reefs. Man has settled in the coastal zone for reasons such as easy accessibility, availability of basic facilities
It is only need the water stops to resist the water from the backfill to pass through the vertical joints. For the retaining wall, all forces act on it are come from the backfill. Unlike the floodwall, hydraulic forces act as part of the loads hit on the wall and may become severe during the flood events. Generally, floodwall possesses a weak foundation condition as it is located in a flood plain, so the uplift forces act as the main reason to cause foundation instability. But, retaining wall does not encounter the weak foundation condition induced by flood
o Introduction Coasts are dynamic natural systems that are constantly changing. The action of waves and wind creates and destroys many coastal features. These features include stacks, caves, cliffs, arches, beaches and spits. o Coastal Management All levels of government have some responsibility for coastal management. Traditionally, the states have the greatest power over the use of the coastal zone.
Each ministry is controlling designated zone by passing laws such as the Harbor Act, Fishing Port Act, and the Public Waterfront Landfill Act. The goal is to cover the development and utilization of Japan's coastal zone. A total of 77 environmental classifications of coastal zone units have already been made (Wakita & Yagi, 2013). Coastal Management Strategy in Australia The Australian mainland coastline length is estimated to be about 35,877 km (see Table 2) with an additional 23,859 km of island coastlines (Australia, 2004). There are 758 estuaries around the country with most located in the tropical and sub-tropical zones (Dennison & Abal, 1999).
A hydroponic system will also use less water than soil based plants because the system is enclosed, which results in less evaporation. Believe it or not, hydroponics is better for the environment because it reduces waste and pollution from soil runoff. The disadvantages of hydroponics are:- • Despite the fact that a hydroponics system has so many advantages, there are actually a few disadvantages as well. The biggest factor for most people is that a quality hydroponics system of any size will cost more than its soil counterpart. Then again, dirt isn’t exactly expensive and you get what you pay for.
