Determining Discharge-Coefficient Ratings for Coastal Structures in Dade CountyFlorida

摘要

This report presents a technique for determining discharge-coefficient ratingsfor coastal structures in Dade County, Fla. These coefficient ratings test the accuracy of discharge determined by theoretical methods and allow more accurate determination of the total amount of water being discharged. Sixteen coastal structure outflows in eastern Data County were measured, and discharge-coefficient ratings were developed from these data. Discharge measurements were taken under a variety of conditions to develop the computed-coefficient ratings, and comparisons were made to the theoretical-coefficient ratings, and comparisons were made to the theoretical-coefficient ratings. Flow regimes were identified, and a least squares fit was used to determine the best estimate of the appropriate coefficients. Uncertainty in the coefficient values was determined from the error in fit of the field data.
