Urban Sewers Evolve Similarly to River Networks

Research Spotlight

Like river systems, engineered drainage networks become increasingly fractal as they grow. 

Beneath city streets, sewer systems direct the flow of wastewater toward treatment plants. Sewer pipe networks also drain storm water to prevent urban flooding. These urban networks perform a landscape drainage function similar to that of natural river networks. Now, a new study by Yang et al. demonstrates for the first time that the two network types also evolve similarly over time....more
