Global extent and distribution of artificial, residential waterways in estuaries
Artificial residential waterways are now widespread in the world's estuaries. We used the global mapping tool, Google Earth, to determine that there are nearly 4000 linear km of artificial waterways globally, covering an area of 270 km2. Residential waterways constructed as open, flow-through c...

Artificial residential waterways are now widespread in the world's estuaries.
