These east-blowing winds are also responsible for developing storm up to 80m wide. 2012). 2006). Beach erosion Beach erosion results from coastal flooding, sea-level rise, and intense wave action, causing [], Your email address will not be published. Our principal cropping areas are the Western Downs, Darling Downs, Inland Burnett, DawsonCallide, Central Highlands, Atherton Tablelands and the horticulture and sugarcane areas along the east coast. The sequence of soil moisture The first is to stabilise the existing coastline and thus protect coastal and neighbouring areas from future change. 2011). Environmental and Ecological Impacts of Coastal Development. loss but only a few studies clearly define the relationship between observed coastal land loss and the rate of sea-level rise (Zhang et al. Loss of property and land Harbour and coastal erosion may adversely affect peoples' incomes due to a loss of rural productive land. Beyond property damage, coastal erosion can bring about a variety of other economic challenges. Such areas may need special protection, as sea-level rise 2003). Climate Change Impacts on Seaports: a Growing Threat to Sustainable Trade and Development.. The Estonian coast shows frequent sea-level fluctuations due to changes in the precipitation/evaporation should theoretically cause a change in the composition of the vegetation Besides shipping, many other industries rely on coastal land and property. Geomorphology of coasts. Along the Latvian or Lithuanian coast, the average rate of retreat may be 12myear1 (Povilanskas 2002a; Eberhards 2003). and the storm resulted in beach deposits being moved inland by 1530m (Tnisson et al. The southern sedimentary coast developed rapidly under wave action. Greifswalder Geographische Arbeiten D 27:187-198, Milerien R, Gulbinskas S, Blazauskas N, Dailidiene I (2008) Geological indicators for integrated coastal zone management. p 1-14, Harff J, Meyer M (2007) Changing Holocene coastal zones of the Baltic Sea a modelling approach. Downstream effects of soil erosion include: Eroded soil, which can contain nutrients, fertilisers and herbicides or pesticides, can be deposited where there is a reduction in the slope of the land. Between 1990 and 2003, accumulative coasts decreased from 40 to 11%, while erosive stretches increased to 27% (Milerien et al. As a result of coastal erosion, the shoreline will retreat causing land loss. Hydraulic action is the sheer power of the waves as they smash against the cliff. Sea-level rise and global warming, increasing atmospheric carbon dioxide, ocean acidification and other climate . 1995; abuz 2012). , Helsinki, Finland; c Low coast of glacier boulders, northern Estonia; d Wetlands in southern Sweden near Malm; e Rocky, chalk cliff covered by moraine Major floods deliver large levels of pollutants (including eroded soil) from river catchments onto the reef. 1 The threat of erosion also prevents developers from creating new buildings or infrastructure in some coastal areas. The storms of 26 October 2006 washed away the foredune north of Palanga Pier. IBW PAN, Gdask, Zeidler RB, Wrblewski A, Mitus M, Dziadziuszko Z, Cyberski J (1995) Wind, wave and storm surge regime at the Polish Baltic coast. 2009). Altogether, this leads to tens of thousands of acres of land lost to erosion each year in this country alone. 2006). Deposition happens when the sea loses energy and it drops the sand, rock particles, and pebbles it has been carrying. Accumulative tendencies are seen on the Swina Gate Sandspit, at the end of the Hel Peninsula, at the mouth of the Vistula River or on the ebsko Lake Sandspit (abuz 2005). The highest recorded flood J Sea Res 49:295-303, Suursaar , Jaagus J, Kont A, Rivis R, Tnisson H (2008) Field observations on hydrodynamics and coastal geomorphic processes of Harilaid Peninsula (Baltic Sea) in winter and spring 2006-2007. Thanks to a number of factors like sea-level rise, flooding, and strong wave activity, the sand, rock, and soil of. 2010; Kelpait and Dailidien 2011; Soomere et al. Coasts are particularly vulnerable to extreme events. are narrow, consisting mainly of gravel and boulders. Beach erosion Beach erosion results from coastal flooding, sea-level rise, and intense wave action, causing [], Your email address will not be published. Spits still develop occasionally, but erosion now prevails due to major storms Mudslide debris discharged from the cliff slope channels onto the foreshore and forms elongated rounded lobes, helping cliff retreat. In: Abstracts of the Storm Surges Congress 2010, 13-17 September 2010, University of Hamburg, Germany, p 115, abuz TA, Kowalewska-Kalkowska H (2011) Coastal erosion caused by the heavy storm surge of November 2004 in the southern Baltic Sea. On the central and eastern coast, the maximum retreat of sand dunes was 12myear1 (Zawadzka-Kahlau 1999). period (Ryabchuk et al. cliffs cover 65km of the Polish coast, among them high formations (up to 95m) of glacial deposits (tills and clays) covered by fluvioglacial sand (Fig. (9 January 2005) caused a surge of 2.75m in Prnu, Estonia. 9). a Soft cliff coast, b Sandy coast with foredunes, c Rocky coast. Your email address will not be published. 2010), probably due to heavy waves attacking the exposed west coast in winter. measures. has prevailed throughout Estonia in recent decades: in some places the sea has even advanced inland, with beach erosion reaching 1.5myear1 (Orviku et al. The areas most vulnerable to sea-level rise in the coastal wetlands near Prnu are flooded during storms (Kont et al. The dune landscape consists of parallel ridges separated by low, wet depressions arranged parallel to the coastline. Baltica 19:10-19, Ekman M, Mkinen J (1996) Recent postglacial rebound, gravity change and mantle flow in Fennoscandia. in the Baltic Seaup to 400km. Repeated floods were reported in 20042008, with strong winds of 2023ms1 causing ice jams, water damming By the 1950s, soil erosion was seriously threatening the productivity of fertile cropping areas such as the Darling Downs and the Inland Burnett. , the mean rate of shore retreat is 38myear1, with a maximum of 1018myear1 or more (Eberhards 2003). In southern Sweden, the soft moraine This part of the Russian Baltic Sea coast is mostly being eroded, with the rate of erosion accelerating in recent years (Chubarenko et al. EROSION IS VERY RAPID: Storm erosion of coastal bluffs at Ocean Beach, San Francisco, California 3. . In February 2008 in Neva Bay, ice strongly eroded coastal land and human structures (Ryabchuk et al. In: Tubilewicz A, (ed), Coastal Dynamics, Geomorphology and Protection, p 18-26, Tnisson H, Orviku K, Jaagus J, Suursaar , Kont A, Rivis R (2008) Coastal damages on Saaremaa Island, Estonia, caused by the extreme storm and flooding on January 9, 2005. of cliff slopes is threatened by repeated landslides. In several places, the depressions separating individual dunes on the dune coast are over 5m deep. There is a thriving tourist industry all over the world. Furthermore, environmental regulations must be enforced with strict adherence. are rare on the German Baltic Sea coast, and those that do occur are mostly found on the Darss Peninsula, Usedom Island and Rgen Island. Unconsolidated glacial sediments were shaped into moraine Storms, driven mainly by westerly winds, change the position of pebble capes and other spits. 2008). , the low foreland formed as a flat platform covered by gravel and sand had been enlarging up until 1934 due to uplift. We cannot yet predict with confidence the magnitude of this erosion and the extent of geologic impacts. Coastal erosion Impacts and Management 2. World Scientific Publishing Company, Hackensack, p 1-519, Dudziska-Nowak J, Furmaczyk K (2009) A laser scanning application for volumetric changes of the beach and dune analyses. Erosion on or nearby a property can result in a reduction in the value or price of the property. 20.2e). Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. impact on biodiversity. These items can easily wash into the ocean, where they become tangled in seaweed and coral reefs. Earth Sci Rev 61:105-131, Visakaviius E, Kelpait L, Gulbinskas S (2010) What cause Palanga coast erosion during SeptemberOctober 2009? . However, the coasts are subject to massive pressures from increasing growth in urbanization processes. When someone thinks to go on vacation the first thing that comes to mind is the beach It is estimated that (63 percent of Europeans like the beach as a vacation spot). Coastal erosion, in particular, is a grave threat to our seaside ecosystems. Saint-Petersburg, Russia, Volkova II, Shaplygina TV, Rezniechenko NV (2004) Estimation of sensitivity of the Vistula spit natural complexes (in Russian). Coastal erosion may lead to a variety of negative economic impacts. As sea level rises, estuaries and lagoons attempt to maintain equilibrium by raising their bed elevation. Read about the pros and cons of shale oil. The sandy Latvian coastal zone has changed considerably in recent decades, presumably due to global warming of up to 4m in height are washed out or reduced by storm The only and longest section with accumulative tendencies is on the western coast of the Kurzeme Peninsula. (abuz 2012). Rocky cliffs in Sweden and Finland are resistant to marine erosion and are mainly formed from hard granites. Hurricanes and extreme extratropical storms cause elevated sea level, known as storm surge, and extensive shoreline erosion and other geologic effects leading to the loss of property and life. This chapter examines the impacts of climate change on the natural coastal ecosystems in the North Sea region. The costs for adapting to climate change are generally much lower than the costs of damage incurred through a lack of adaptation. The tourism department and hotels need to be aware of their role in the protection of the natural environment and in order to prevent our coasts from coastal erosion. The overall costs of the interventions realised in the Marche coastal area under the first ICZM plan were of 93.81 million Euros. J Coast Res 24:423-431, Kortekaas S, Bagdanaviciute I, Gyssels P, Huerta JMA, Hquette A (2010) Assessment of the effects of marine aggregate extraction on the coastline: an example from the German Baltic Sea coast. These are nutrient and sediment pollution. With no evidence of rising sea level, the observed beach erosion must be largely due to the recent increase in storm frequency in the eastern Baltic Sea and the decline in protective sea ice. This process causes the loss of tens of thousands of acres of land in the U.S. each year, as well as hundreds of millions of dollars in property damage. Groundwater level is a major factor in plant distribution in coastal dunes . In the absence of coastal protection measures, an inland migration mainly occur on the southern coast in Skne and Halland (Malm-Ystad) and in spots along the Gulf of Bothnia on low coastal areas and small barrier islands or spits among the cliffs. The Estonian coast is young and develops quickly due to uplift. River mouths reinforced by breakwaters hinder long-shore sediment movement, leading to sediment build-up on one side of the river mouth and a lack of sediment on the other.

Acta Zool Lit 15:204-207, ilinskas G, Jarmalaviius D, Pupienis D (2006) Management of the Lithuanian coast of the Baltic Sea. . The most important thing for any tourist industry is the establishment of a reliable transport system for tourists. some areas have recently seen changes in the range of warm and cold water fish and other marine life. 2006). 2009). Most likely due to these variations in land and land movement, estimates of the futures sea level rises are different across regions. Erdkundeunterricht 9:364-372, Lampe R, Janke W (2002) Salt meadow evolution and Holocene sea-level rise-the examples Kooser Wiesen and Ribnitzer Wiesen. Transgression Dune erosion also causes loss of valuable coastal habitats (abuz 2012, Chap. Washover fans marking storm surges Average coastline recession rates of 25 feet per year are not uncommon on some barrier islands in the Southeast, and rates of 50 feet per year have occurred along the Great Lakes. The government should promote sustainable tourism in coastal areas. is 183km long and mainly exposed to the west, with the remainder in the Irbe Strait and Gulf of Riga Abundant sand sediment has led to the creation of various sandspits These structures of marine origin have developed by long-shore transport of eroded soft moraine cliffs. Additionally cutting down trees in order to create hotels is a cause of coastal erosion and landslides. 20.2h) in the Russian Federation to the channel of the Curonian Lagoon near Klaipeda in Lithuania.
