Assessing the Flow Characteristics of Amanyi Stream for a Small Scale HydroPower Development

ABSTRACT

The study assessed the flow characteristics of Amanyi stream for a mini hydro power development for Neke Uno, Isi-Uzo Local Government Area of Enugu State, Nigeria. The stream has a maximum flow discharge, Qmax of 8.5m3/s, average discharge, Qav of 6.9m3/s, minimum dependable discharge, Qmin of 4.21m3/s and a selected design discharge Qd of 6.37m3/s. Topographic survey and plant layout showed a head of 3.63m (low head) which is possible for power generation. It was also determined that for the available head and selected design discharge, a power output of 154KW is achievable. This power can meet 83% of power requirement for Neke Uno Community near the hydropower plant. This power however, can be increased by some modification of the existing topography.

It is recommended that the hydropower development of the Amanyi stream be given serious consideration under public private agreement with some financial assistance from the United Nations Industrial Development Organization (UNIDO) to make it feasible for the community. This could be a pilot hydropower supply source for rural areas that have similar streams and topography.
