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.

Guidelines for water management modelling
eWater has published these guidelines to promote a best practice, quality assured approach to application of modelling tools, primarily to address water management problems, and provision of decision support to end-users of model results.
The Guidelines for water management modelling: Towards best-practice model application are the first of the hierarchy of more detailed supporting guidelines for model domains relevant to eWater Source.
The latest supporting documents are:
Guidelines for modelling water sharing rules
Guidelines for rainfall-runoff modelling
Guidelines for groundwater-surfacewater interactions modelling.
Guidelines for modelling rainfall-funoff modelling Guidelines for modelling groundwater-surface water interaction

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.

eFlow uses environmental flow objectives to generate an altered flow regime and determine how much additional water would be required to achieve the new flow regime.

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.
|
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.
|
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.

Source - public version, is a special version of eWater Source – Australia's national hydrological modelling platform. It is designed to simulate all aspects of water resource systems to support Integrated Water Resource Management (IWRM) studies in urban, catchments and river basins including human and ecological influences.
eWater Source — an Australian-wide collaboration effort backed by the Australian government — is built to meet the myriad climatic, geographic, water policy and governance settings across the country.
eWater Source is Australia’s national hydrological modelling platform which integrates water resource assessment with policy. An adaptive customisable platform which enables the technical assessment of water balance is combined with a unique governance modelling capability to produce water accounts and operate rivers according to agreements and treaties.
Source is the outcome of two decades of collaboration between State and Federal Government water organisations, leading universities, water utilities and regional rural water authorities through the eWater CRC and it’s predecessors the CRC for Catchment Hydrology and the CRC for Freshwater Ecology. Endorsed and defensible – Source has been endorsed by the Council of Australian Governments as the national hydrological modelling platform.

Water Quality Analyser is for water managers, scientists and engineers who need to analyse time-series, monitor in-stream water quality, estimate pollutant loads, or set future water quality targets.
With a straight-forward user interface and a focus on visualising data inputs and outputs, Water Quality Analyser helps to identify water quality trends and simplifies the path to a summary assessment.
