Predicting the effects of water abstraction and land use intensification on gravel bed rivers

Publication date:  December 2015
Publication reference number:  CR 217

This report produced by the National Institute of Water and Atmospheric Research introduces Bayesian Networks as a decision-support tool for councils and their communities to use when developing freshwater management options. The report uses gravel bed rivers as an example though many of the principles can be extrapolated to other forms of water bodies.

A useful linkage diagram is also provided, which demonstrates the main factors that affect a wide range of values in gravel bed rivers.

Six Bayesian Network files are also provided, which can be used with software called Netica, accessed from

More information about using the files is provided in the report.
