The Point of Sangomar is a sand spit located on the Atlantic Ocean at the mouth of the Saloum Delta, which marks the end of the Petite Côte west of Senegal. This narrow sandbar extends south about twenty kilometers from Palmarin Diakhanor. Long threatened by coastal erosion, the fragile cord was again broken by a tidal wave in 1987, giving birth to the island of Sangomar. The gap between this new island and the point where the village of Djiffer is continues to widen. == Geomorphology and environmental == The rupture in Sangomar is the result of a natural process for the past few thousand years,〔« Les études pluridisciplinaires côtières au Sénégal », UNESCO ()〕 which has also been noticed by sailors. In 1891, it was found that the gap had widened from 25 to 30m since 1886.〔Bouteiller, J., ''"De Saint-Louis à Sierra-Leone. Huit ans de navigation dans les rivières du Sud"'', A. Challamel, Paris, 1891, p. 199 ()〕 In the twentieth century, several breaks were reported including: 1909, 1928, 1960, 1970, etc. The latest occurred on 27 February 1987 at a place called Lagoba. A year later, the gap was reported to be 1 km wide, and ten years later, about 4 km.〔 Several camps and buildings were destroyed. The fish packing plant at Djifer was closed in 1996.〔 The village located 4 km north of the first breakpoint is increasingly threatened and authorities are considering the evacuation of its inhabitants to the new port of Diakhanor.〔Vézia, Frédérick , ''"Sénégal : Sine-Saloum, la forêt de l'océan"'', Éditions de La Martinière, Paris, 2009, p. 21 ISBN 978-2732439655〕 Parallel to the phenomenon of erosion, occurs a process of sedimentation: the extremity of the new Southern Island of Sangomar increases by 100 m per annum to the south and, on the opposite bank, the outskirts of the villages of Niodior and Dionewar are silting considerably, reducing traffic of vessels and contributing to the isolation of populations.〔 All these phenomena are closely followed by a body established with the support of UNESCO in 1984, the multidisciplinary team that studies coastal ecosystems (EPEEC).〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Point of Sangomar」の詳細全文を読む スポンサード リンク
