Flooding. "To defeat a network, you need a network..."

A case study in managing complexity and a networked problem.

The town of Pickering in North Yorkshire flooded 4 times in 10 years, causing £7m in damage in 2007 and protest marches by the local inhabitants.

Forced by government refusal to fund traditional flood protection the local council consulted a wide range of experts and academics and looked at local history before undertaking a widespread scheme to manage the network of water sources leading to the construction of 160 "porous dams" which only cost £2m and which have been credited with saving the town from the worst of the recent (2015-16) unprecedented flooding that has wrought devastation elsewhere in the UK.
