This project represents the first attempt to characterize the interaction between largely undeveloped catchments and the coastal environment of the Kimberley and the role large coastal inlets play in ... moretransforming material transported from those catchments during large flows before it reaches the coast. This project has also attempted to provide the first assessment of how future changes in climate might impact these processes. Future climate scenarios suggest there is not a great difference in mean rainfall or flows between the three possible future climates and the Historical sequence. To investigate the physical-biogeochemical interactions in this region, a second model was established with a focus on the coastal margin and estuarine portion, and then additionally configured to simulate turbidity (including particle resuspension), and inorganic and organic carbon and nutrients. The model was validated and then used to assess how far terrestrial nutrients might extend from the river into Walcott Inlet and possibly Collier Bay. Flows greater than 300m3/s were shown to dominate nutrient loads within Walcott Inlet itself (>50% of total load) and significantly contribute to the inner reaches of Collier Bay (>15% of total load).less

1157.1 NRM Murray Basin - Water activity - Published 02 May 2016
This model demonstrates a methodology for simulating interactions between wetlands and underlying shallow groundwater in the Lower Limestone Coast Prescribed Wells Area. Specifically, the model simula... moretes changes in wetland water levels to variations in water tables. A variant of the industry standard groundwater flow simulation code MODFLOW (i.e. MODFLOW-OWHM) was used as the basis for this approach. Significant components of the water mass balances for both wetland and groundwater domains were included. Of particular novelty was the use of a combined approach to simultaneously represent recharge and evapotranspiration. Model files also include Python language post-processing scripts, which may be used to produce statistical summaries of wetland surface water persistence.
The model was demonstrated using a synthetic input dataset. Results of the synthetic demonstration, including the calculated salinisation risk metric, indicated the potential for managed surface water additions to negate the effects of long-term water table decline on the persistence of wetland surface water levels.less
1212.3 Goyder E.2.3 SE Phase 2 - Wetland connectivity modelling - Published 24 Jun 2015
A numerical model to simulate salt transport in the unsaturated zone of two selected sites of the Lockyer Valley, namely, Forest Hill and Tent Hill. Those two sites were selected as they had signific... moreant amounts of salt stored in their unsaturated zone, which extends to about 20 m. HYDRUS-1D of Šimůnek and colleagues (2008) was used to model water flow, solute transport, and root water uptake in those sites.
A total of twelve simulations were run, six for each site. Two irrigation options were considered, the first using the currently available water at each of the sites, and the second using PRW. For each of those options (1 and 2), two vegetation types were considered: shallow-rooted (series W) and deep-rooted (series D). An additional scenario was considered for the shallow-rooted vegetation where intensive irrigation was adopted; this option represented a worst-case scenario for salt mobilisation and transport. Simulation time was varied depending on the irrigation scenario, which was 100 years and 28 years for moderate and intensive irrigation scenarios, respectively.less

1006.2 SEQ Stormwater/MAR Feasibility - Hydrology and streamflow - Published 10 Dec 2012
These data provide rasterised layers of climatic variables hypothesised to explain spatial patterns in biological diversity at continental scales for use with statistical modelling tools. Specificall... morey, these data were derived for modelling the compositional pattern of multiple species with environmental factors such as climate, soil and topography using the statistical technique Generalised Dissimilarity Modelling applied to continental Australia.
Climate variables are monthly mean values for minimum temperature, maximum temperature, relative humidity, vapour pressure, precipitation, aridity, solar radiation, evaporation, wind and others. Some of these monthly variables were used to generate growth indices (using the GROCLIM module of ANUCLIM).
These data for Generalised Dissimilarity Modelling (GDM) analysis were masked to consistently define data/nodata values and supplied in DIVA-GIS floating-grid format in the WGS84 geographic reference system.
NOTE: Full details of the data, with a list of data sources and bibliography, are provided in a PDF file included as part of the data collection.less
