The Thouet () is a tributary river of the Loire in the Poitou-Charentes and Pays de la Loire régions of France. The Thouet rises at Secondigny, close to the source of the Sèvre Nantaise, and joins the Loire just to the west of Saumur. It is long, and drains an area of . The river's name derives from the ancient Gallic word for tranquil.〔(【引用サイトリンク】 France for Walkers - The Thouet Valley )〕 ==Course of the river== The Thouet rises in the Gâtine Vendéenne, the most southern outcrop of the Massif Armoricain, at 225 metres altitude. The Massif armoricain is made up of volcanic and metamorphic rocks dating back to the Paleozoic era. This impermeable land does not result in any important aquifers but is an area of significant rainfall runoff. From the source to Parthenay the river flows in a generally east-west direction.〔 To the east of Parthenay, the river turns north and flows on a generally northward heading for the rest of its course. Between Saint-Loup-Lamairé and Thouars, the river flows onto the Paris Basin, an area of sedimentary rocks where successive marine deposits of periods from the Triassic to the Pliocene were laid down. The nature of the rocks here allows the formation of an aquifer whose water reserves support the river in times of low flow.〔〔〔 In order downstream, the Thouet flows through:〔〔 * Secondigny * Azay-sur-Thouet * le Tallud * Parthenay * Châtillon-sur-Thouet * Gourgé * Saint-Loup-Lamairé * Airvault * Saint-Généroux * Missé * Thouars * Taizon * Saint-Martin-de-Sanzay * Montreuil-Bellay * Saint-Just-sur-Dive * Saumur The principal tributaries of the River Thouet are:〔 * The Viette, at Parthenay on the right bank * The Palais, at Parthenay on the left bank * The Cébron, at Saint-Loup-Lamairé on the left bank * The Thouaret, near Taizé on the left bank * The Argenton, at Saint-Martin-de-Sanzay on the left bank * The Losse, at Montreuil-Bellay on the right bank * The Dive, at Saint-Just-sur-Dive on the right bank. For much of its length, the Thouet is paralleled by the GR 36 long-distance walking route, which connects Ouistreham, on the coast of the English Channel, with Bourg-Madame, on the border with Spain. This stretch of the path traces the footsteps of pilgrims from Brittany and Normandy on their way to Santiago de Compostela, and in places crosses the river using the same fords, packhorse bridges and stepping stones the pilgrims would have used.〔〔(【引用サイトリンク】 GR Long Hiking Trails )〕 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「Thouet」の詳細全文を読む スポンサード リンク
