The conference will be a forum for the dissemination of the latest ideas in the development and application of advanced computational techniques to problems in water resources and related fields, including surface and subsurface hydrology, environmental hydrodynamics, ecohydrology, contaminant remediation, carbon sequestration, climate change, and nuclear waste storage. The inexorable increase in raw computational power, software developments, availability of on-line hydrologic data, and recent advances in cyber-infrastructure make this a particularly exciting time for computational applications to water resources and geoscience challenges.
