Catchment Tools



BC2C (Biophysical Capacity to Change) is a tool for estimating catchment scale water and salt export quantities, following changes in landuse in upland catchments. Intended for use with regional data sets, it gives an indication of changes under different scenarios (e.g. change in percentage tree cover) that can be used to pin-point and prioritise areas for further investigation.


CatchmentSIM is a 3D-GIS topographic parameterisation and hydrologic analysis model. The model automatically delineates watershed and subcatchment boundaries, generalises geophysical parameters and provides in-depth analysis tools to examine and compare the hydrologic properties of subcatchments.


CMSS (Catchment Management Support System) predicts average annual loads of pollutants (usually Total Phosphorus and Total Nitrogen) at the sub-catchment level, according to different land use types.


FCFC (Forest Cover Flow Change model) is used to adjust daily time series observed or simulated flow records for significant changes in forest cover. It is applicable to small to medium unregulated catchments with major changes in the proportion of forest cover and can be used to adjust inputs to larger scale catchment models.


RRL (Rainfall-Runoff Library) simulates catchment runoff by using daily rainfall and evapotranspiration data. The models may be applied to catchments from 10 km2 to 10,000 km2 on a daily time step.


SCL (Stochastic Climate Library) is a source of models for generating climate data, including rainfall, evaporation or temperature, at multiple timescales, across single or multiple sites.


SedNet identifies sources and sinks of sediment and nutrients in river networks and predicts spatial patterns of erosion and sediment load. This tool can help target management actions to improve water quality and riverine habitat.


SHPA (Soil Hydrological Properties of Australia) is a collection of maps and GIS data that provide estimates of soil hydrologic properties across Australia based on the Atlas of Australian Soils and interpretations by Neil McKenzie.


NSFM (Non-parametric Seasonal Forecast Model) is a non-parametric seasonal forecasting model that forecasts continuous exceedance probabilities of streamflow (or any other hydroclimate variable). NSFM forecasts the exceedance probabilities of streamflow several months ahead by exploiting the lag relationship between streamflow and ENSO (El Nino/Southern Oscillation) and the serial correlation in streamflow.


IHACRES (Identification of unit Hydrographs And Component flows from Rainfall, Evaporation and Streamflow data) is a catchment-scale, rainfall-streamflow, modelling methodology that characterises the dynamic relationship between rainfall and streamflow, using rainfall and temperature (or potential evaporation) data, and predicts streamflow.


CLASS-CGM (Crop Growth Model) can be used to simulate growth of main C3 field crop types such as wheat, barley, canola, sunflowers and C4 field crop types such as maize and sorghum. CLASS-CGM can also be used to simulate crop growth impacts on water balance from CLASS-U3M-1D.


CLASS-PGM (Pasture Growth Model) can be used to simulate growth of composite pasture types of multiple perennial or annual pasture species and to simulate pasture growth impacts on water balance from CLASS-U3M-1D.


CLASS-SA (Spatial Analyst) is a spatial modelling tool that can be used to generate climate zones, multi-resolution DEMs, wetness index, lateral multiple flow paths, accumulation and dispersion of water and solutes from hazard areas, estimation of soil depth, soil material distribution and soil moisture storage capacity in different parts of the landscape.


CLASS-U3M-1D (Unsaturated Moisture Movement Model) can be used for estimating recharge, plant water use and soil evaporation across the soil profile at daily time steps using the Richards' equation.
