In addition to using adaptive management, in the face of uncertainty, good design requires the adoption of measures that enhance infrastructure resilience. Resilience of a system determines how quickly it recovers from crisis. The Good Practice Note (GPN) lists several measures for enhancing infrastructure resilience. Both structural and nonstructural measures should be considered, along with their desirable time of implementation during the project life cycle including: (a) structural measures such as suitable types of spillway / outlet works, operational system, installation of fuse plugs/gates, hard fill type dams to resist overtopping, etc. and (b) non¬structural measures, such as optimal reservoir operation, early warning, emergency preparedness plans, and so on. There should be no bias toward structural or nonstructural solutions; in fact, good solutions inevitably involve an intelligent combination of both.
