The infographic presents the optimisation process during site-specific evaluations. Deficiencies can be identified at an early stage, during technical and hydraulic characterisation and during study of fish migration. Optimisation proposals can then be developed. Thus the efficacy of optimisation measures implemented can be tested during the course of the evaluation process.

The infographic is part of a manual that focuses on the site specific evaluation of the efficiency of fish protection and bypass systems. Standardized evaluation principles are defined to promote significant, comparable studies. The manual constitutes a framework for an objective evaluation process.
