This is not a river, but a canal. The Northsea canal connects Amsterdam with the Nortsea. The location is not "Hofgeest", but the towns of Velsen and Beverwijk

Changed to a "canal" instead a river as suggested by Henk Stek. Unfortunatelly, the location name was provided by Panoramio, not by me, so, i can´t change it.
