Sediments, which represent the skin of the Earth, begin their trip to rivers with the strength got from rainfalls, fl oods and different normal procedures. because of shipping of sediments, rivers increase with quite a few appearances and services, and play a vital function within the actions of humans and the lifestyles cycles of alternative species. River sediment, as a standard subject for river administration, has been the Read more...

Planning and hydraulic design of bypass tunnel for sluicing sediment past Asahi Reservir, 19 Congress of Large Dams, Florence.

There is no measured data of the bypassed sediment, but the riverbed variation upstream the diversion weir is so small that almost all the particles having the similar composition to that of the upstream riverbed should have been bypassed. The Asahi dam bypass system was put into use in 1998 and about 83,000 m3 of sediment was discharged via the tunnel in that year. Because the coarse sediment is transported through the tunnel, considerable abrasion must be taken into account. The survey in 1998 revealed that the tunnel’s invert concrete with the designed strength of 36 N/mm2 wore 46 mm a year and that part with 70 N/mm2 wore 14 mm a year.

If an adequate tractive force throughout the impound reach as well as the downstream of the dam can be produced, this method is applicable for even a coarse sediment and, in some cases, it is economical in comparison to the mechanical sediment removal that necessitates high cost dredging, the acquisition of sediment disposal area, land transportation and the associated engineering. Attention should be paid to the possible very high sediment concentrations downstream that might cause several hazards.
