Siphonic Removal of Sediments in Water Reservoirs — Additional Experiment for Model Revision
M. Sadatomi, T. Nagano, and A. Kawahara
Abstract—In water reservoirs and dams in Japan, the
increment of sediments causes capacity reduction and water
quality deterioration. In the present paper, the siphonic
sediment removal system, invented by Sadatomi, is
experimentally studied using different sized siphons and sands.
From the present and our previous data for spherical particles,
a new correlation of particle volume flow rate fraction is
obtained. By incorporating the new correlation, the
performance prediction model proposed in our previous study
is revised. The revised model is validated by testing against the
present data as well as previous data. Thus, the revised model is
promising as a design tool of actual large scale systems.
Index Terms—Removal, sediments, siphon, water reservoirs.
