Freeboard Criteria and Guidelines for Computing Freeboard Allowances for Storage Dams by Anonim Pdf
This document presents Bureau of Reclamation policy pertaining to freeboard allowances for storage dams. This edition of the ACER Technical Memorandum No. 2 is significantly different from the original 1981 edition. This second edition offers a simplified approach to freeboard calculations under certain conditions and suggests a probabilistic approach if the simplified computations are not appropriate. More extensive wind data are also now available to facilitate the use of probability. The wind effects on water have also been revised according to the latest Corps of Engineer's studies. The crest elevations of both new and existing dams may be evaluated on the basis of calculated risk.
