The Dendre river is a Belgian river with its source in the Walloon region and the downstream part in the Flemish region. It is a tributary of the Schelde river. The Walloon part of the Dendre basin has an extension of about 800 sq. Km and the length of the river is approximately 40 km. At about 20 km from its source the main river the West Dendre joins with a tributary the East Dendre. An important artificial channel, Canal Blaton converges at this confluence and links the Meuse basin to the Schelde basin through a series of weirs. The basin coverage is dominated by agricultural land with important industrial or urban centres. The topography of the land is characterised by medium-low hills. Three water level and discharge gauges are placed along the Dendre and its tributary, whilst two water level meters are situated in the Dendre, close to the Flemish boundary. Four rainfall gauges are also installed.
