Conventional hydropower systems that can take advantage of low head movement of water require substantial flow rates …. However, these systems cannot harvest hydro energy from small sources of water with low head and low discharge, such as … streams and creeks. The reciprocating hydropower system discussed in this paper can harvest power from such low flow discharge …
