Levrière

The Levrière is a river of the Norman Vexin, affluent of the Epte (Right Bank).

Geography

Long, the river 24 kilometers is born with Bézu-the-Forest in the oriental party of the Forêt of Lyons and runs in direction of south-east, parallel to the Epte, with 3 kilometers in the west of this one. With Bézu-Saint-Éloi, it receives, out of Right Bank, the Bonde which comes from Étrépagny, then it joins the Epte downstream from Gisors with Neaufles-Saint-Martin at the end of a course completely located in the Département of the Eure. The catchment Area of Levrière is made of plates chalky, covered with silt, slightly elevated and affected small deformations of Armorican direction. The sides of the valley are occupied, out of left bank, by chalk outcrops of the Crétacé and, out of Right Bank, by colluviums Quaternaire S.

With the discharge system, the flow of Levrière, within the framework of a oceanic rain mode, is estimated at 2,3 m ³ /s for a catchment area of a surface of 318 km ². This last is affected by a oceanic Climat to which the annual average temperature is close to 10 °C with a thermal Amplitude annual low (8 °C) and whose precipitations reach 700 mm per annum.
