Air Pressures Over Reservoir, Canal, And Water Catchment Surfaces Exposed To Wind, Allen Ray Dedrick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface air pressure differentials that occur over reservoirs, canals, and water-catchment aprons in high-wind conditions were determined by the use of models in a wind tunnel. Such information was needed concerning the magnitude and location of destructive wind forces on water barriers constructed of exposed flexible membrane liners. Rigid models, without a membrane, were used to measure airpressure differentials.

Air-pressure differentials were dependent on geometric configuration and were independent of viccous forces above the critical Reynolds number which was determined experimentally. The geometric factors studied with respect to reservoirs and canals included approach slope, approach slope length, leeward slope, and …
