The growing pressure on the world's water resources coupled with the increasing vulnerability of society to the impacts of extreme events, has resulted in a need to consider explicitly the stochastic processes which underly the environment in which water resources & hydraulic infrastructure is constructed. The effective and practical integration of the theory and application of hydraulics with probabilistic analysis is one of the most challenging tasks facing researchers and practioners working in design, operation, and management of water resources infrastructure under these conditions. This symposium reports on the latest developments in stochastic hydraulics across a wide range of applications including river hydraulics sediment transport, catchment hydraulics, groundwater, waves and coastal process, hydraulic networks and structure, hydrology, risk and reliability in hydraulic design and water resources in general.
