Eco Modeller is a tool for building, storing and running quantitative models of ecological responses to physical and biological factors, for use in comparing the merits of alternative natural resource management scenarios.


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.


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.


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.


NSFM (Non-parametric Seasonal Forecasting Model) forecasts continuous exceedance probabilities of streamflow (or any other hydroclimate variable).


RAP (River Analysis Package) is a collection of 3 tools: Hydraulic Analysis - examines the hydraulic characteristics of river channels to determine the optimal discharge for a river reach based on specified rules. Time Series Analysis - calculates summary statistics of time series data, including hydrological metrics. Time Series Manager - manipulates and manages time series data.


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.


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.
