The northern part of the borough is sloping (Sandy Flanders) with a highest point of 19 metres near Edewalle, and a lowest point of approximately 4 metres in the Handzamevaart valley. The surrounding bowl is approximately 7 metres high. Various streams, including the Calvebeek, flow to the southwest and waters into the Handzamevaart. The Handzamevaart is a medium-sized stream that crosses Zarrenstraat and Steenstraat and eventually flows into the IJzer in Diksmuide. This stream runs through Werken by 'de Broeken', a flood plain now used for agricultural purposes. Between the Oude Gracht (Zarren) and the Handzamevaart there is a channel with a pumping station which systematically pumps excess water in to the Handzamevaart.
