Technical Construction

Year by year, the coastal zones are constantly changing due to the action of waves, tides, and human impact. The shoreline has been particularly influenced by the human impact over the years, especially by the location of hydro-technical construction to prevent erosion or floods. Thus, the problem of coastal erosion appears as an effect of sediment transport, modifying shore morphology. In this paper, we intend to study the hydrodynamic of the Romanian Coastal zone and the wave regime alteration due to the protection systems.

Of the 14 inlets belonging to 12 coastal lagoons in the coastal zone of Central Vietnam, the unstable group consists of 4 inlets; the less stable group comprises 4 inlets and the relatively stable group has 6 inlets. For the feasibility and effectiveness, the constructions of stabilizing lagoonal inlets must be multi-purpose and multi-benefit, such as maintenance of ecosystems, opening to the sea for ships and boats, flood drainage and pollution limitation. They need to be combined with other development activities to reduce costs and increase benefits, for example in conjunction with seaports, fishing harbours, typhoon shelters and tourism... Solutions to stabilise the lagoonal inlets consist of 5 groups: Constructing groins for control of inlets; dredging lagoonal inlets and bottom; preventing coastal erosion outside the lagoons; stabilizing the lagoon banks and the surrounding sandy areas; regulating water supplies in the catchments into the lagoons. Depending on the natural conditions and degrees of human impact, the priority solution has been proposed for each lagoonal inlet.

The Impact

Coastal zones have great diversity of resources. The shallow water zones contain the most of plant and benthic communities. A description of relief and type of ground is needed for the rigorous monitoring of biota and environmental condition of coastal zone. Generally, on the basis of these data the investigation methods of the coastal zone are selected. The shallows research strategy has been developed by us for northern part of the Lake Ladoga. If the coastal areas are characterized by great depth and flat topography, then sonar’s can be used to describe them and samples of ground can be taken by bottom grabs. In the Lake Ladoga these methods don’t operate correctly by reason of the compound bottom relief and the fact that a sizeable part of the bottom is occupied by hard ground. Therefore, our investigations base on the diving transect method of Golikov and Skarlato (1965). A diver moves along transects. He registers the depth, length to coastline, water temperature, relief and ground, edificators and records video. In the laboratory all these data are decoded and used for mapping of bays. Studies of plant communities have been performed and strategy for research of benthic communities in complex relief and hard ground conditions has been developed based on the descriptions of shallow waters. Description of the Malay Nikonovskia Bay bottom has given an opportunity to estimate changes in the bottom of the bay under the influence of the trout farm.

The Impact

Anthropogenic impact on lithodynamics of the coastal zone changes the natural dynamics of bottom sediments, which leads to increased abrasion and swelling of beaches, activation of landslide processes creating a threat of destruction of the coastal infrastructure. The article aims at providing an overview of the scientific literature on the anthropogenic impact on lithodynamics of the coastal zone of the southern and western coasts of the Black Sea (shores of Romania, Bulgaria and Turkey). The work shows that with all the differences in the natural conditions of the coastal zones of these countries the types of anthropogenic effects they undergo are almost the same. These include: hydrotechnical construction without regard to the impact on the neighbouring coast sections; reduction of solid river flow due to river regulation by reservoirs; construction of capital facilities directly on the beaches; illegal extraction of sand from beaches and river beds; dredging with sale of the extracted material to construction companies; covering of cliffs by various structures; destruction of coastal dunes, etc. The main negative consequences of these actions are reflected in disruption of natural dynamics and shortages of bottom sediments, changes in the coastline, reduced aesthetic attractiveness and accessibility of shores, destruction of coastal ecosystems. The article also provides information on the legislation of these countries regarding environmental management in the coastal zone

Zone Management

At the World Bank, coastal zone management (CZM) is a part of Integrated Coastal Management (ICM), is an interdisciplinary roomates and Intersectoral approach to problem definition and solutions in the coastal zone, it includes a range of initiatives that promote the environmentally sustainable development of coastal areas, and encompasses a range of activities such as community-based management of coastal resources, large-scale infrastructure development (ports, industrial and residential parks, etc..), pollution and erosion control, aquaculture, tourism and recreation, oil spill contingency planning, and navigational risk assessment.CZM is a process of governance that consists of the legal andinstitutional framework Necessary to Ensure that development and management plans for coastal zones are integrated with environmental and social goals, and are developed with the participation of those affected.The purpose of the ICM is to maximize the benefits providedby the coastal zone and to minimize the conflicts and Harmful effects of activities on social, cultural and environmental resources.

Decision Making Processes

In 2008, the Council of the European Union adopted the “Protocol on Integrated Coastal Zone Management” (ICZM Protocol), then ratified by Decision No. 2010/631/EU. The ICZM Protocol defines integrated coastal zone management as a dynamic and flexible process that accounts for the relations between coastal ecosystems and landscape as well as the activities and the uses that characterize coastal areas. Integrated management of coastal zones is still a critical process in terms of translating theory into practice. In this theoretical framework, strategic environmental assessment (SEA) helps to improve decision-making processes related to coastal spatial planning by integrating development goals and sustainability criteria. This study proposes a methodological approach concerning ICZM-based decision-making processes at the local level. The methodology is implemented in relation to three case studies concerning three towns located in southwest Sardinia. The results show a general consistency between the analyzed plans in terms of objectives and themes. Three specific issues are particularly relevant in terms of integration of economic and social objectives and sustainability goals, that is, relations between beach services and coastal ecosystems, protection of coastal ecosystems, and accessibility to the coastal zones.
