The paper provides a low-head hydropower energy resource harvester (HyPER) design of 4-blade impeller with a fixed pitch blade angle. Based on a previous site evaluation and maximum power potential estimated without any modifications to the irrigation structure, the proposed objective of exploiting the estimated power will be met from harvester prototypes with portable, compact modular design.
