Erosion on the beach has deteriorated
Since the construction of port and jetties, natural erosive phenomenon has worsened. In addition, the gradual change in the direction of the waves by the displacement of the cyclone-and sea-level rise is to worsen the picture. A palliative, although expensive, would be to dredge the harbor mouth to reconstitute the natural flow of sand.
The beach erosion marplatensesSi Mar del Plata well enjoy it from its status as a major seaside resort, this matrix is being challenged tourist from erosion phenomenon affecting beaches. Today, this problem not only of concern to its residents and tourists each year, which have less surface area of the beach-but, as if it were a domino effect, the consequences have become visible in other seaside resorts located to the north.
To understand more about the erosion in this area, Thelma contacted the doctor in geology Jorge Codignotto, a researcher at the University of Buenos Aires and CONICET. Going back to the origins of the problem, Codignotto explained that “in Mar del Plata there is a marine drift current that leads north sandy material. When in 1914 it became the south jetty of the port, the circuit is interrupted. And then the coast just north of the south breakwater of the contribution was devoid of sand. It was a mild coastal erosion, but it was magnified. “
“Between 1918 and 1919-continued the researcher became the north jetty and a few years later, he formed a beach south of the first breakwater which accumulated material. Exactly, that was the sand that would not reach the beaches located to the north. And so all the costs began to erode. “
In an attempt to halt the erosion process, between 1922 and ’80, were built several jetties. That is a cross-shore structures, aimed at trapping sand that migrated from the south, but that did not meet their missions. According to the geologist, “derived sand along the south jetty and there was deposited exactly where material should not be placed.” And besides, “all the sand that were caught with the breakwaters, sand was not reached the northern beaches, which accentuated the erosion.” Read the rest of this entry »
Coastal erosion and its impact on marine ecosystems
Caja Madrid and the Coastal Ecology Institute (IEL) have signed an agreement to control the degradation of the coast of Alicante and its effects on marine communities of special ecological significance.
One of the main objectives of the project is to study the effect of erosion on the prairies of Posidonia oceanica
The IEL project aims to provide a monitoring system of coastal erosion and its effects on marine ecosystems in several municipalities in Alicante including Natura 2000 European Directive on the conservation of biodiversity. Municipalities are Guardamar, Santa Pola, Alicante, El Campello, Torrevieja and Benidorm.
From a historical perspective, we will analyze the alterations in the coastal and marine communities until today.

Thus, we will study the influence of the main factors that have led to changes in the coastline. These principles include, feedback from beaches, decreased input from rivers, building ports and promenades, and so on. They provide solutions to the government to reduce or try to correct the different conditions.
Through this initiative is to educate both the society and government on how to produce coastal erosion and the effects it has on the environment. To accomplish this, we will develop a multidisciplinary study covering aspects oceanographic, meteorological and geographical factors.
Coastal Ecology Institute is a Valencian Community Foundation whose main function is to contribute to the conservation of marine ecosystems, coastal and land through research, conducting technical work, counseling and encouraging respect for our natural environment.
The protection and care of the environment is one of the cornerstones of the Obra Social Caja Madrid, which each year contributes to this through various actions such as the announcement of grants to environmental projects and the implementation of activities and exhibitions that aim raise public awareness about the need to protect the environment.
