CloudGMS has been commissioned by DENR to develop a numerical groundwater model of the aquifers within the central area of the WDWCD to improve confidence in the sustainability of the groundwater resources, as this is the area within the WCD with greatest potential for intensive development.

Leaf Area Index (LAI) Areas of vegetation that use groundwater typically exhibit low seasonal variability of photosynthetic activity. The inter-annual variability of the vegetation activity can therefore contain useful information to assist mapping of groundwater discharge areas (Tweed, LeBlanc, Webb, & Lubczynski, 2007). Vegetation that is relatively lush in comparison to surrounding areas is often associated with discharge areas. Leaf area index (LAI) is often used as an indicator to identify this type of vegetation. LAI is defined as the one sided green leaf area per unit ground area in broadleaf canopies. LAI is therefore considered a strong indicator of water availability in semi-arid to arid environments (Hatton & Evans, 1998) and can be used as a proxy for vegetation water use. Total LAI was estimated using the product MOD15A2 centred on the study area (201 km wide 201 km length) from the MODIS 163 Land Product Subsets project (http://daac.ornl.gov/MODIS/). ORNL DAAC. 2008.
