Hydro Power Turbine Design

[aspearin1]

I am curious if there is a reference out there comparing different turbine system designs. (preferebly free... but open to other.) I imagine design iterations are plentiful, and I wish to know if some designs are more fitting to particular flow conditions than others...

I have seen some TVA turbine studies, consider a internet web search.
