For durability take a real good look at your terrain and high water mark, consider a penstock/pipe to a Banki turbine out of the way of flood waters or building a weir to a vortex system, either way you should be able to get at least 1Kw with good survivability depending on how you build the system.
Good luck, I'm in the middle of design/build of my own similar system.

I'm going forward with my own design/build as much for the experience as for the power, will post designs and results as they happen.
