How many canals are there in the Netherlands?

There are many canals and remnants of canals in Suriname. The Surinamese capital city at Paramaribo alone has over a dozen canals and sluices dating from plantation days. Canals and sluices were used extensively on Suriname's plantations to control the drainage of water. Specifically, Paramaribo was surrounded by plantations that took care of their drainage through canals and sluices.
