Catchment Classification builds on a range of projects and will assist in the development of key land and water strategies. Links to related projects A National Classification of Catchments for Salinity Control (NCC) The outcomes of this Rural Industries Research and Development Corporation (RIRDC) / Land and Water Resources Research and Development Corporation (LWRRDC) research resulted in the classification on which the Catchment Classification Project is based. National Land and Water Resources Audit Australian Natural Resources Atlas The National Land and Water Resources Audit is developing the Australian Natural Resources Atlas to provide ready access to information to support natural resource management. The Atlas will be able to be accessed and used by managers and community groups to help in their planning and management activities. Dryland Salinity theme Catchment Classification complements a range of products arising from the National Land and Water Resources Audit. National Dryland Salinity Program (NDSP) The Murray-Darling Basin Commission is an important partner in the NDSP Program. Catchment Classification will assist in achieving the outcomes of the NDSP Program. TOOLs to Investigate and Manage Dryland Salinity The TOOLs project has released an information package with a bio-physical component based solidly around the principles of catchment classification. The outputs of Catchment Classification will complement and support the TOOLs project in providing one of the most significant tools for catchment planning. Salt Trends The 1997 Murray-Darling Basin Commission report 'Salt Trends' provides information on the historic trend in salt concentration and streamflow saltloads in the Murray-Darling Basin. The work on salt trends is integral to this project. Basin Salinity Audit The Salinity Audit is a major advance in our predictive capacity within the Murray-Darling Basin. It provides a basis for framing the Basin-wide salinity management strategy. Landmark The primary objective of Landmark is to identify the need for land use and land management change and policy responses to facilitate change in broad-acre dryland regions of the Murray-Darling Basin (MDB). Catchment Classification complements this by providing assistance for catchment scale salinisation processes understanding based on the GFS framework. Heartlands The CSIRO Heartlands initiative is focussed on identifying workable vegetation design strategies to effectively rehabilitate agricultural landscapes - solutions that integrate social and economic objectives for rural communities as well as environmental imperatives. Salinity, water quality, water yield, biodiversity, and carbon sequestration potential are some of the issues being addressed. The Heartlands initiative directly combines on-ground works with a program of applied research, development and knowledge exchange. Modelling tools used in the project FLOWTUBE model FLOWTUBE is a simple one dimensional groundwater calculator based on Darcy's Law developed by CSIRO for use by agency staff, consultants and farmers to allow "what if" questions to be asked of management options. The conceptualisation, construction, calibration and predictive use of numerical simulations can be demonstrated in a very simple way using the FLOWTUBE model. HARSD model HARSD is an acronym for Hydrogeomorphic Analysis of Regional Spatial Data. The underlying assumption is that groundwater or Hydraulic Head Surface is a smoothed version of the surface topography and that linear relationships between measured ground water flow levels (bore readings) and surface elevation can be used to construct reasonably accurate groundwater surfaces. These surfaces can then be used for steady-state groundwater flow modelling. WAVES model WAVES is a one-dimensional daily-timestep model that simulates the fluxes of mass and energy between the atmosphere, vegetation, and soil systems, which has been under development since 1993. It is a process-based model that couples these systems by modelling the interactions and feedbacks between them. WAVES attempts to model each sub-system with a consistent level of detail, so that no area is over emphasized or requires too many parameters, and similarly no area is treated in a trivial manner. More than this, WAVES tries to strike a balance between the complexity of the model as a whole, the usefulness of the model and its ease of use, and the accuracy of the model outputs. If these balances have been struck, then WAVES should be easy enough to use, but accurate enough to believe. REALM model The REsource ALlocation Model is a computer program that can simulate the operation of water supply systems during droughts as well as during periods of normal and high streamflows. REALM is a generalised computer program that can simulate simple water supply systems as well as large and complex ones such as the River Murray system in south eastern Australia. It is general in that any water supply system can be configured as a network of nodes and carriers representing reservoirs, demand centres, waterways, pipes, etc. |
