Abstract:
Model tests of outlet transitions consiting of various lengths and elevations of horizontal aprons with sidewalls flared one on eight were conducted to determine the maximum limiting discharges for which satisfactory performance could be maintained with various conditions of tailwater. Results are presented in dimensionless parameters and design charts for ready determination of a the maximum discharges permissible with a given diameter culvert, given lengths of flared outlet transitions, and various depths of tailwater, and b the lengths of flared outlet transition required for a given diameter culvert, a given discharge, and various depths of tailwater. This type of protection is considered effective for those outlets subject to various tailwaters, provided the discharges are relatively small, and for the usual range of discharges, provided sufficient and relatively large tailwater depths will exist downstream.
