This dataset provides flood inundation extent and duration for the Fitzroy catchment in Western Australia for the flood events of 2001, 2002, 2006, 2007, 2009, 2011 and 2014. The data are in raster fo... morermat. The values in the raster file shows the duration of inundation (days) during an event. The following are the start and end time for each flood.

Northern Australian Basin Assessment:: Water Resource Assessments - - Published 01 Oct 2018
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

1006.8 SEQ Water Losses - Estimation of monolayer water quality effects - Published 25 Aug 2016
Contains a model for estimating the cost-effectiveness of rainwater tanks in South East Queensland (SEQ) covering the regions of Brisbane, Moreton Bay, Sunshine Coast, Ipswich and the Gold Coast. Thi... mores model runs in the @RISK software package (an application for Microsoft Excel), which uses Monte Carlo simulation to generate a probability distribution of the cost-effectiveness and to undertake sensitivity analysis.
The input variables draw upon recent research in the Urban Water Security Research Alliance which provided data about variables of cost and yield for rainwater tanks in the region. Input variables include:
Capital costs (rainwater tank, the pump, laying of a concrete slab for the tank to rest upon as well as plumbing and installation of both the tank and the pump);
Annual costs (operating costs such as energy use for the pump, maintenance costs such as desludging as well as replacement cycles for pumps and tanks over the period of analysis);
Yield variables (household demand and end use, connected roof area, rainfall pattern as well as the effect of up-scaling from a single rainwater tank to consider the yield of a large number of tanks).

1006.2 SEQ Lockyer Valley - Groundwater modelling - Published 22 Mar 2013
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
