Climate change impacts on rainfall and hydrological regimes can have profound consequences for water resource management, agriculture and the environment through changes to the magnitude of water supply, inter- and intra-seasonal variability in rainfall occurrence, effectiveness of ground water recharge, adequacy of urban storm drainage etc. This session invites submission on cross-disciplinary research with a focus on how hydroclimate projections can provide meaningful information about future climate change impacts on water users in our communities, built and planned infrastructure and the environment as well as ideas on what information is required, but not yet provided by the climate science community.
