Повний текст джерелаCoastal areas are important interface environments between marine and terrestrial ecosystems and are populated by abundant living communities. Among these coastal areas, the Charente coastline is an area of strong economic activities related, among others, to aquaculture, fishing and tourism, thus requiring a good quality of water and environment. However, this coastal area is under the influence of many contaminants: phytosanitary products, hydrocarbons, heavy metals, etc., of which water is the main vector. In order to preserve the Pertuis, the Marine Natural Park has set up a management plan determining the measures of protection, knowledge, enhancement and sustainable development to be implemented for the next 15 years. The QUALIPERTUIS project aims to combine a phase of laboratory tests and on-site measurements in order to provide a new perspective on the causes of bivalve mortality, as well as to understand more broadly the impact of environmental factors influencing the sanitary state of bivalves in port areas and coastal waters. In partnership with the La Rochelle Marina and Port Atlantique La Rochelle, environmental biomonitoring studies have been set up in port areas and in the Pertuis with three species of bivalve molluscs: the black scallop Mimachlamys varia, the hollow oyster Crassostrea gigas and the blue mussel Mytilus edulis. Seasonal environmental monitoring has been carried out on a total of thirteen study sites, distributed in the port areas and the Pertuis

Повний текст джерелаAt the beginning of the 19 th century, the navy underwent an accelerated technical change. The "old port" with medieval origins of La Rochelle no longer meets the needs of navigation, which gives rise to the digging of an effective interior basin in 1808. This equipment quickly proves insufficient and in the middle of the century, the construction of a second basin outside the walls was essential and saw the Ville-en-Bois district develop nearby. Quickly, in turn, in the years 1850-1860, this new basin no longer met modern maritime requirements. The construction of a third wet dock in deep water was then considered for the first time. The question of location arises. The answer comes from the hydrographer engineer Bouquet de la Grye who, after having studied the various possibilities of the bay, proposed in 1876 a place 5 km west of the city, with would be the creation of the deep water port of La Pallice. The visit of the Minister of Public Works, Freycinet, in 1878, endorsed this major project which had become national in scope. Work began in 1880 until August 19, 1890, the date of inauguration by President Sadi Carnot. On June 5, 1891, the port establishment was opened to navigation, and traffic grew steadily. The First World War highlights the advantages of La Pallice and its important role in national defence, but the port presented as modern in 1890 soon becomes cramped to receive increasingly large ships. The construction of a deep-water stopover mole was adopted in 1923, to be partly operational before the Second World War. This thesis, which is part of urban history, also aims to demonstrate how the creation of the port of La Pallice has enabled La Rochelle to renew its great maritime destiny by reviving its marchant economy

Повний текст джерелаOn July 13th 2001, the city of La Rochelle, involved with Paris in a candidacy for Olympic Games 2008, was seething with excitement. At the head of local population, elected representatives and managers of local yachting activities were waiting for the verdict of the International Olympic Committee, which would turn the small coastal city into a world-class centre of water-based sports. Although Beijing, and later London in 2012 were preferred, the Paris candidacy has awarded La Rochelle an international reputation. This thesis aims to describe how the city, primarily a fishing and trade harbour, hosted a marina in the early 1970’s that eventually became the largest one of the French Atlantic coast, with more than 4800 moorings. Based on theoretical concepts underlying leisure boating activities, a comprehensive study was carried out on documentary data since World War II. Tracing back the history of the local yachting club Société des Régates Rochelaises and the life of renowned sailors shed a new light on the root causes of coastal management in the city. In the early 1960’s, leisure yachting was a fresh boost to declining economic activities. Since then, ambitious projects were planned with the aim of turning La Rochelle into a seaside resort. The race for coastal planning was engaged at the broader scale of the Charente Maritime department, which was almost nicknamed "Leisure coasts". The La Rochelle marina was an important tool of territorial development and a valuable element of the city, but its sprawling growth eventually became a threat to seaside tourism

Повний текст джерелаSituated in the heart of the bay of Biscay, La Rochelle, right from its foundation, at the beginning of the XIIth century, was a community of fishermen. It then became one of the most dynamic cities in western France. In 1890 the commercial port moved to a new site, liberating the old port in the city centre for fishing activities. Many sailing ships came to sell their fish on an attractive fish market boosted by the railway connection to the inland part of the country in 1857. A new era started with industrial trawling, a major innovation in Great Britain. In 1871, the English shipowner Craggs tried to introduce steam-powered trawling but suffered a setback . However from 1904 to 1920 important armaments in industrial trawling were created, making La Rochelle, in this early period of expansion, the second fishing port in France and the first one on the Atlantic coast. After the stagnation of French fisheries and a crisis of Rochelais steam-powered trawlers, a new expansion of the port occured after WWII. In the sixties, La Rochelle became the 4th fishing port in France, until in 1965 a break in industrial fishing activities resulted in the loss of the last big trawlers in 1994. There have been numerous documents about other fishing ports in France. This study aims to concentrate on the history of industrial fishing in the port of La Rochelle over a century, highlighting its economic, sociological, political and ecological dimensions. For this purpose a comparative study has been made, analysing the characteristics and the reasons of this expansion as well as the ones of a rapid and premature decline

Повний текст джерелаPorts are presents on all maritime and river fronts of the world, and represent major interfaces in the development of territories. The natural siltation of these calm areas can obstruct waterways and prevent these infrastructures from fulfilling their primary function as a shelter for boats. This often involves the implementation of expensive and time-consuming dredging operations to restore depths compatible with navigation. Les Minimes marina (La Rochelle, France), which is one of the largest marinas on the Atlantic coast, is not spared by this phenomenon and requires dredging activities for a large part of the year. In response to this problem, the marina and La Rochelle University, has wanted to understand better the natural environment and the processes leading to the accumulation of sediments in the marina. By combining an instrumental in situ approach with operational numerical modelling, the objective of this thesis was, therefore, to characterise the hydro-sedimentary dynamics of the area. Quantification of the impact of floating structures (boats, pontoons) on marina hydrodynamics was firstly carried out. The second field of study aimed to study the circulation of water masses and their renewal about the effect of wind and tide. The observations collected made it possible to study spatial and temporal sediment dynamics, under the action of wind, tide and waves. Thus, numerous siltation control measures have been implemented and analysed to provide solutions and research perspectives in view with siltation and dredging management
