The Braye du Valle is the area between the main Island of Guernsey and Le Clos du Valle, which was a tidal island to the north. ==Origins== The original reason for the separation of the north of the Island of Guernsey may relate to seismic disturbances or changes in the sea level. The rise and fall of the tide in Guernsey is over which creates energy to move loose materials. The Braye was open to the sea and the shoreline moves with the waves and the tides. Gravel and sand are deposited onshore, only to be swept back offshore. Storms batter the coast, and tides flood areas on a daily basis. The premiere forces that shapes the coastal landscape, however, are waves. Beaches are not fixed features, they are dynamic environments.〔 (【引用サイトリンク】title=Coast and Shore )〕 It is likely that at one time a land bridge connected the two sections next to the Vale church, before the sea broke through. In 1204 it is reported that the Royal Court of Guernsey visited the Braye du Valle to replace boundary markers that had been washed away.〔 The Braye covered around 350 acres of sand, gravel, clay and bog. Water channels one or two feet deep ran its entire length. Salterns and marshy meadows that flooded at high tide formed the sides. Saltpans operated on the southern side. long, up to wide and to deep at high water.〔 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「Braye du Valle, Guernsey」の詳細全文を読む スポンサード リンク
