Abstract
A method and device are provided for improving the reoxygenation of water in line with dams. At the crown of the dam a plurality of studs are disposed which form a comb and cause thorough division of the overflowing sheet of water. This sheet of water undergoes a veritable disintegration which increases the air-water interface and causes an increase in the oxygenation of the overflowing flow.
Claims2
A method for improving reoxygenation of water in line with a dam, comprising the steps of:
- (a) providing a dam,
- (b) causing a sheet of water to travel over the crown of said dam, and
- (c) substantially increasing the penetration of atmospheric oxygen into the sheet of water by providing elements at the crown of said dam spaced sufficient to cause disintegration of said sheet of water.
A device for improving reoxygenation of water in line with a dam, comprising:
- (a) a dam, and
- (b) means at the crown of said dam spaced sufficient for substantially increasing the penetration of atmospheric oxygen into a sheet of water passing over the crown of said dam, said means comprising:
- (c) a plurality of projecting elements disposed at the crown of said dam for causing division of a sheet of water flowing over the crown of said dam.
