"Dealing with future floods will also require the use of the best and most innovative tools available. This includes the use of state-of-the-art technology to develop "smart" levees and flood control systems that will enable more control over water management systems during a flood and allow the possibility to act, for instance when sensors indicate the probability of a levee breach or an overtopping. These tools are available or under development right now". (Galloway, A California Challenge - Flooding in the Central Valley, October 15, 2007, p. 26)
