Abstract

In this paper we introduce a small hydro plant that uses Archimedes screws. This is an alternate solution to small-scale hydropower as it exploits unused resources such as small rivers or streams. Based on hydrological study, we developped a theoretical static model to estimate the annual energy production depending on flow rate, hydrostatic head and Archimedes screw efficiency variations. Then, we studied the flood and low-water periods in order to exclude harmful climatic events of the annual energy production estimation, used for the Archimedes screw design.
