Coastal Management Coastal Management is the understanding of physical/natural processes that impact coastlands (such as erosion, transportation, and deposition), and the application of this knowledge for the sustainable preservation of these coastal zones. It is aimed at protecting our coastline from erosion and preserving the natural ecosystems within and around these coastal zones. The protection/management of coastlands is important because they are naturally flood prone areas which tend to be densely populated and possess economic potential to agriculture, tourism and other industries (“Internet Geography”, n.d). The erosion of coastlines can also lead to the receding of cliffs and the degradation of beach materials. General objectives
However, due to the use of hard measures, downstream of the measures the erosion has UROSION Case Study 21 increased. In between the towns with a fixed coastline, bays seem to be developing due to this erosion. The sea defences seem to be creating artificial headlands because erosion on both sides continues. As time progresses this could mean that the headlands (towns) become more and more exposed to the force of the waves, while the coast in between the headlands will erode more and more until a stable bay is
Meiofauna and macrofauna inhabiting the finer grain size beaches are confined to the oxygenated top few centimetres (Rodriguez et al., 2003), in order to avoid unoxygenated, stagnant black sand. On the other hand, the meiofauna found on beaches with large grain sizes can reach deep into the sediment (Rodriguez et al., 2003), in order to avoid the effects of wave action at the surface. Macrofauna can be negatively affected by wave action on beaches with high wave action and, therefore, tend to reside in more favourable beaches that have less wave action (McLachlan et al., 1996; Rodriguez et al.,
Ved : Cloud seeding Dikes - Holland Thames barrier Sea wall A seawall is a coastal defense system, constructed where the sea (or other coastal water bodies), impact directly upon the coastal land. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. As a seawall is a man made structure made of cement, it will interfere with the land and water sediment exchanging. Seawalls are classified as : “A hard engineering shore based structure used to provide protection and to lessen coastal erosion.”. However, a range of environmental problems and issues may arise from the construction of a seawall, including disrupting natural sediment movement / exchange.
Abstract Through this study, we will highlight the mangrove plants in Jazan area by using advance mathematical models, because of its importance and great benefit,and summed up the importance of these plants in the sea shores to prevent corrosion and bring a large number of migratory birds. They are also resistant to the difficult circumstances that other plants cannot and contain nutrients that are used as animal feed privileged. Unfortunately, these plants are reduced to drift due to the ongoing reclamation processes that occur on the Red Sea coast. This research aims to use fuzzy topology in the diagnosis of the current situation of the mangrove plants scattered on the coast of Jazan area using fuzzy interior operator and fuzzy closure
This is not surprising as erosion has been identified as a major coastal problem in the country, as much as 1390 kilometer or 27% of the Malaysian coastline is presently subjected to the erosion of varying degrees of severity (Sharifah Mastura Syed Abdullah, 1992). Besides, coastal erosion seriously threatens the economic and human activities along the coastal zones (Jamaluddin, 1982). Recent economic advancement in the coastline has led to a tremendous increase in development projects in the country, for instance, construction of airport track prolongs till the sea, agriculture sector, tourism activities and settlements houses. Apart from that, most of the coastline area is part of government assets and own by settlers. Less the coastline owns by private agencies like most of the developed countries.
What are the different types of civil engineering? There are many different type of filed in civil engineering that you can chose from. The filed are Coastal, Earthquake, Environmental, Structural, Transport, Urban, Water resources and etc. Coastal engineering: Costal engineering is the study of continues at the beach and construction within the costal environment/zone. Coastal engineering is about protecting our beaches and coastal areas from flood and erosion.
Soft Engineering Soft engineering techniques deploy the use of more natural measures utilising sustainable ecological principles to improve the resistance of coastland areas to erosion and flooding. This is achieved through utilising vegetation (mangroves) and other natural systems like dunes and beaches which absorb and eventually adapt to becoming more accommodative of the impacts felt via wave action, resulting in little or no destruction (or more stable conditions) at the land- water interface/boundary (Geography LWC, 2015). Some advantages (pros) of soft engineering coastal management practices are that they are generally less expensive as opposed to hard engineering measures; they’re more attractive since they blend in with the natural environment; and they provide more long term-sustainable solutions without disrupting natural processes and ecosystems. Its disadvantages/ cons however is that there is a lower likelihood of resistance to severe storms with the exception of some soft engineering techniques like the planting of mangroves; there is need for frequent monitoring and maintenance in some cases; it may be a time consuming process before these natural systems can effectively provide optimum resistance (for instance-the time taken for afforestation or for the growing/ replanting of mangroves) and lastly, there is a periodic
Environmental Education, Safety/Services and Water Quality. By achieving high standards to these criteria can promote sustainability of coastal resources in both national and local levels. Although some criteria of Blue Flag applicable to coastal zone management, it is adequate to properly assist management of beaches and does not guarantee the quality of the beach. Although this award mechanisms aims to attract tourism, it does not account public perceptions to this strategy. Most of these rating schemes highly focus on recreational nature of beaches, giving lesser attention for the organization and the dynamics of various beach associations, geomorphology, performance of governing bodies and objectives.
Introduction Since last century, there has been a major change in the way that coastlines have been used. Beach tourism has become increasingly popular, fishing industry has expanded and residential and defensive construction sites has grown on the coastline. These developments due to the population rise, has generated major environmental changes, including t degradation of coastal resources (Agbayani, 1995) such as decrease in mangrove forests (White & Cruz-Trinidad, 1998), destruction of sea grass ecosystem (CRMP, 2004), damaged fish habitats (Aldona, Ferminb, & Agbayania, 2011) and coral reef devastation (Gomez, Aliño, Yap, & Licuanan, 1994). In addition, climate change is putting pressure on coastal developments through impacts such as
