Ternoise

The riverTernoise (French pronunciation:; Dutch: Ternaas) is one of the small chalk streams that flow from the plateau of the southern Boulonnais and Picardy, via the Canche, into the English Channel. The basin of the Ternoise extends to 342 square kilometres (132 mi) and lies in the southern end of the département of Pas-de-Calais. It is one of the rivers of the Seven Valleys tourist area. Its name, and that of the region Ternois, is derived from the FrankishpagusTeruanensis.
