Environmental impact
Turbines can have visual impact and produce some noise, but these can be mitigated relatively easily. The main issue is to maintain the river's ecology by restricting the proportion of the total flow diverted through the turbine.
You will need to talk to the relevant planning authorities to ensure the site and design are acceptable and identify any other permissions required.
