The City of Greater Geelong requires specific climate templates (rainfall and potential evapotranspiration) to be used for stormwater treatment modelling using MUSIC. These climate templates are available for download below.
Two rainfall regions have been identified for the City of Greater Geelong. Areas with rainfall <500mm annually have been designated “Little River” and those with rainfall >500mm annually have been designated “Geelong North” to coincide with the Bureau of Meteorology station names. The figure outlining the rainfall regions is available for download below.
It is recommended the following minimum
periods be used:
- 10 years for WSUD treatment performance and
- 20 years for stormwater harvesting, large scale
integrated water management plans and strategies (>100 ha) and catchments
with an impervious fraction <20% or where pervious flows are substantial.
The climate templates are available for download are:
- 10 year Geelong North: 1971-1980_6min
- 20 year Geelong North: 1971-1990_6min
- 10 year Little River: 1992-2001_6min
- 20 year Little River: 1989-2008_6min
The user should select the
appropriate template for the project location and type of analysis.
Note that as the templates have been infilled to improve quality, they
cannot be reproduced by creating a template directly from the raw data.
