Local Erosion of the Channel After Reinforcement of the Millrace of the Votkinsk Hydroelectric Power Plant

详细

Changes during operation in the state of the segment where concrete reinforcement of the water channels of the Votkinsk hydroelectric plant join the Kama River are examined. The reasons for erosion during the 1990’s, including lowering of the water levels in the lower millrace, are examined. It is noted that after reinforcement of the hopper during 1998 – 2000, the state of this segment remains satisfactory and does not threaten the safety of the equipment.
