REVIEW OF DETERMINATION OF INSTREAM FLOW REQUIREMENTS WITH SPECIAL APPLICATION TO AUSTRALIA

A critical examination of the techniques used to assess and specify en vironmental instream flow requirements is provided. The strengths and weaknesses of individual techniques are evaluated on both an absolute and a comparative basis. Particular attention is given to the problem of specifying environmental flow requirements in Australia where the h ydrology has distinctly different characteristics to those in countrie s where most of the models for prediction of instream flow requirement s were developed. Broad recommendations as to the suitability and use of the different techniques for different conditions are provided.
