Meanings

1. A barrier built across a steeply sloping road or trail in order to direct the flow of water and prevent erosion; waterbreak.
   • Most waterbar spacing, however, is in the magnitude of 80 - 120 feet. 1973, Information Series - Volumes 7-13:
   • With waterbar placement every 20 feet, in addition to mulching, the expected erosion would be less than 1 ton per acre, well within the tolerance level. 1980, United States. Bureau of Land Management. Casper District, Buffalo resource area oil and gas environmental assessment, page 152:
   • The angle at which the waterbar lies across a trail is important. Too close to the perpendicular, and silt will build up behind the waterbar; too small an angle will cause the trail to wash out. 1987, Thomas H. Mikkelsen, Donald B. Neuwirth, Jake Widman, Public Beaches: An Owners' Manual, page 29:
2. Waterstop.
   • A suitable waterbar should be incorporated in the joint to prevent the ingress of water. 2013, Roy Chudley, Roger Greeno, Building Construction Handbook, page 293:
   • A valve type of waterbar therefore is maintained in the stressed condition caused by shrinkage of the concrete during setting. 1968, Peter L. Critchell, Joints and cracks in concrete, page 93:
   • It is essential to prevent distortion of the waterbar before and during concreting; to some extent this can be ensured by the use of clips, attached to the dumb-bell and wired to the reinforcement. 1973, Engineering Equipment Users Association., The Use of Plastics Materials in Building, page 21:
