Which among the following reduces the capacity of reservoir and causes

1.	Which among the following reduces the capacity of reservoir and causes rapid erosion of turbine blades?(a) Contamination of highly corrosive material(b) Sedimentation effect(c) Submerged vegetation(d) Solid contaminationI got this question by my college director while I was bunking the class.Query is from Site Selection for Hydro Electric Power Plants in section Hydro Electric Power Plant of Energy Engineering
Answer» The correct choice is (b) Sedimentation effect Easy explanation: SEDIMENTS in the aquatic ECOSYSTEM are analogous to SOIL in the terrestrial ecosystem as they are the SOURCE of substrate nutrients, and micro- and MACRO flora and -fauna that are the basis of support to living aquatic resources.
