Local Experience with Micro Hydro Technology is a technical paper that was later added into the CD3WD project. It is academic, so it can be hard to read, but it is a theoretical work of little practical use. It actually uses real sites and describes actual usage of the technology.
It does a fine job of explaining why micro hydro technology is a good choice where available and why it is sustainable.
It is an older document, so there is a focus on the Oil Crisis of the 70’s, but not so much to detract from the actual information on water power.
In the rare event that you have no idea what microhydro is, I have taken the liberty to pull an excerpt from its Wikipedia page:
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro. These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net metering is offered. There are many of these installations around the world, particularly in developing nations as they can provide an economical source of energy without the purchase of fuel.Local Experience with Micro Hydro Technology
