spillway channel การใช้

A cofferdam was constructed for excavation of the tailrace and spillway channel, and subsequently removed.
The waterway was formed as a glacial spillway channel at the end of the last ice age.
It is located on the left flank with a wide, uncontrolled concrete overflow, ogee spillway crest and spillway channel lined with reinforced concrete for the first.
One of the engineering wonders of the ancient world was the $ imyarites ( ~ 115 BC ) who undertook further improvements, creating a structure high, with five spillway channels, two masonry-reinforced sluices, a settling pond, and a canal to a distribution tank.
The rehabilitation project consisted of reconstructing the colonnades at the ends of the dam; cleaning and repairing all stone masonry surfaces on the dam, reconstructing the lower pavilions, reconstructing the dam s downstream terrace, reconstructing the spillway and spillway channel, cleaning the spillway discharge pipe, cleaning the internal galleries, installing new lighting and doors, reconstructing the Upper Gate Chamber, Lower Valve Chamber and Maintenance House, and performing final grading and landscaping towards end of the project.
