Full description
This assessment and related data examines water resources in the South East Coast (Victoria) region in 2009–10 and over recent decades. Seasonal variability and trends in modelled water flows, stores and levels are considered at the regional level and also in more detail at sites for selected rivers, wetlands and aquifers. Information on water use is also provided for selected urban centres and irrigation areas. It begins with an overview of key data and information on water flows, stores and use in the region in recent times followed by a brief description of the region. Surface water quality, which is important in any water resources assessment, is not addressed. At the time of writing, suitable quality controlled and assured surface water quality data from the Australian Water
Resources Information System (Bureau of Meteorology 2011a) were not available. Groundwater and water use are only partially addressed for the same reason. In future reports, these aspects will be dealt with more thoroughly as suitable data become operationally available.
Key data and information
The assessment presents the 2009–10 annual landscape water flows and the change in accessible surface water storage in the South East Coast (Victoria) region. Rainfall for the year was in the top end of the average range and evapotranspiration was in the lower part of the average range (see Table 5-1). However, the annual landscape water yield1 total was below average as a result of the substantial increase in soil moisture. There was a rise in surface water storage volumes which can
be attributed to the fact that most of the storages are located in the northern headwaters, part of which experienced average landscape water yield totals.
