Scope/research

Assess

Regulator (Study site)

Research different design aspects

Slope, turbulence, slot width etc

Different designs

Future need: 1. Improved understanding of local physiology and ecology

Future need: 2. Ensuring developers and managers have the information!

Future need: 3. Putting it all into practice in a coordinated way
