How much of the Netherlands is affected by the problem regulated by the Hoogheemraadschap van Rijnland?
Hoogheemraadschap van Rijnland The Hoogheemraadschap van Rijnland is the oldest water board of the Netherlands, having received its first commission to protect the land from flooding back in 1248 from William II of Holland. It conducts water control activities in the general area known as Rijnland. The Netherlands has 27 Waterboards or "Waterschappen" acting independently from the National government administration to manage the continuing Dutch struggle against water.
South Limburg (Netherlands) South Limburg (Dutch: "Zuid-Limburg", Limburgish: "Zuud-Limburg") is both a COROP (statistical) region as well as a "landstreek" (area) of the Netherlands located in the province of Limburg. The Dutch term "landstreek", literally translated "land area/region", means that the area is not an administrative region but an area that displays cohesion with regard to culture and landscape. With regards to South Limburg this deals with its hilly landscape, especially in the Heuvelland region, sunken lanes, an abundance of castles, and the regional language Limburgish spoken by a significant part of the population alongside Dutch. The region also contains the highest point above sea level in mainland Netherlands, the Vaalserberg being 322.5 m above sea level (the highest point of the entire country is in the Caribbean Netherlands' island of Saba, namely Mount Scenery being 887 m above sea level).
