The design of hydro intakes is usually based on a desire to achieve low intake losses and an acceptable approach flow distribution to the turbine. Generally, velocities in the intake canal are low, therefore canal losses are small, and the major concerns become flow distribution at the intake and trash rack losses. Model studies are often used to develop an acceptable design, and this paper discusses the concerns that should be covered in such studies.
