Designing better sewer junction manholes / by J. Marsalek.: En36-539/48-1986E-PDF
"Head losses at sewer junction manholes are controlled by both the junction geometry and flow characteristics. Among geometrical parameters, junction benchings were found particularly important and their effects on junction head losses were therefore studied in scale models of selected manholes. The junction manholes studied included manholes with a 90° bend, junctions of a main with a lateral, and junctions of two opposed laterals. Full-pipe depth benchings with U-shape cross-sections proved to be very effective in reducing junction head losses"--Abstract.
