HYDRAULIC PERFORMANCE OF CONFLICT MANHOLES

This report details a performance analysis of conflict junction boxes, employed when stormwater lines intersect utility conduits. A variety of configurations currently used by the Florida Department of Transportation were tested and rated for turbulent loss characteristics. Special consideration was given to vertical position of the conflict relative to the storm lines. The results were then used to predict full scale performance and design methods were suggested. Several alternative configurations were considered and recommendations for possible adoption made.
