4.3.         Regional Modelling
4.3.1.       Model Objectives
An assessment of the total catchment conveying runoff to the watercourse that bounds the site has been
undertaken to determine the likely pollutant loads generated within the catchment.

4.3.2.       Catchment Description
Mapping of the catchment reveals the total area contributing runoff to the waterway bounding the site is
approximately 3600 ha, as illustrated by Figure 5. Further assessment of the catchment has been
undertaken using the Queensland Land Use Mapping Program (QLUMP). QLUMP has updated land use
mapping in the South-East Queensland Natural Resource Management Region to 2011 or later. Mapping
has been compiled at the catchment level, to assess the land uses within the catchment and determine the
areas associated with each designated land use. A copy of the QLUMP mapping extract for this catchment
and associated land uses is included as Figure 6.
