SIGNAL scoring system for river bio-assessment by community groups

SIGNAL stands for ‘Stream Invertebrate Grade Number – Average Level.’ It is a simple scoring system for macro-invertebrate (‘water bug’) samples from Australian rivers. A SIGNAL score gives an indication of water quality in the river from which the sample was collected. Rivers with high SIGNAL scores are likely to have low levels of salinity, turbidity and nutrients such as nitrogen and phosphorus. They (more)...

The Bayesian Network Models for Environmental Flow Decision-making

This final report summerises the activities and outcomes of the Land & Water Australia Project - Environmental Flow Bayesian Network Decision-Making Framework. The development of two Bayesian Network models used as a decision-support tool for determining environmental flows in major rivers in Australia are reported on. The first eFlows BN model was for the Latrobe River in Victoria, a river system that is highly regulated and (more)...

Dynamic Non-Market Valuation of Ecosystem Services

This study combines non market valuation and bio economic modelling in a dynamic model of ecosystem services.  First, because non market valuation and bio economic models use different concepts of valuation, the values of ecosystem services are defined. Next, an analytical solution is derived which includes a dynamic Lancaster demand system and new methods for welfare analysis.  Finally, both revealed and stated preference methods are proposed for estimating the value of ecosystem (more)...
