Archimedes Screw Turbine parameters consist of two types of parameters. The external and the internal parameters. There are three types of external parameters which is the radius of the screw's outer cylinder turbine, R o; the total length of the screw turbine, L and the slope or angle of the screw turbine, α (Rorres, 2000). All of the

Archimedean screws are often touted as 'fish friendly' hydro turbines, which they undoubtedly are, though we at Renewables First would say that all hydro systems should be fish friendly, regardless of turbine type. In non-screw hydro systems this just means well designed intake screens and fish passes / by passes would be required.
The function of the Archimedes Screw Turbine has recently been changed into a turbine to generate energy (Hellman 2003). Some of the advantages of the Archimedes Screw Turbine is its ability to ope-rate optimally in a low head condition (Williamson et al. 2011), and and can also operate at large discharge (Lashofer et al. 2012).
Archimedes Screws Turbines (ASTs) are a new form of small hydroelectric powerplant that can be applied even in low head sites. ASTs offer a clean and renewable source of energy and are safer for wildlife and especially fish than other hydro generation options. As with other energy solutions, ASTs are not a global solution for all situations.
