Excerpt from Physical Model Studies of Head-Discharge Relationships for Steel Z-Section Water-Level Control Structures In late 1978, the Water Conservation Structures Laboratory, Stillwater, Okla., initiated a model study to rate structure S-13. In June 1979, the water-quality work on the Taylor Creek Watershed was expanded. In addition to increasing the nutrient pollution work, a study was started to determine the water quality before and after initiation of best management practices in the watershed. This new emphasis on water quality increased the need for and importance of head-discharge ratings for structures S-13 and s-13b. This report presents the descriptions of the proto types and physical models, the procedures followed, and the analyses and results of the physical-model studies conducted to determine the head-discharge ratings for structures 53-13 and s-13b.
