Abstract:
This research project is not concerned with the hydraulic performance of basic flow measurement structures which are to be found in British and International Standards. It is concerned with the adaptation or augmentation of Standard gauging structures to aid the migration of fish and is intended to ensure that these adaptations do not significantly degrade the accuracy of the structure as a flow measurement device. The research will ultimately provide specifications for fish migration adaptations or augmentations which can be introduced without significantly affecting flow measurement performance. This Technical Report on Phase 1 of the project gives the results of a literature review of readily available information. It also contains the results of a questionnaire and some follow-up interviews with interested parties. A complementary Laboratory Proposal report (not released to public) has been prepared which interprets the findings of this Technical Report in terms of priorities for future laboratory work in Phase 2, and is summarised within this report. Thus the aim of Phase 1 is to review current knowledge in order to define the most useful and productive way forward. In particular it provides the justification for future, accurate, hydrometric modelling of possible solutions in Phase 2.
