National overview

This chapter provides a national scale assessment of climate and landscape water flows and stores
in 2011–12. It reports on:

  • modelled landscape water balance outputs including precipitation, evapotranspiration and landscape water yield
  • Australian climate drivers and their impact on precipitation
  • changes in the volume of water in major storages and modelled soil moisture
  • national urban and agricultural water use and supply
  • nationally significant precipitation and flood events experienced during the year.
