Backwater Curves,provide, for steady flow, the most general surface profile under a given discharge for specified boundary conditions. Usually, their computation is lengthy but they are required if backwater and drawdown effects have to be determined..Chapter 8 presents a simplified method to determine backwater cur

Losses in Flow, types of losses are described in detail for conduit flow..The . are given by the transition law developed by Colebrook and White and by the solution of the equation of Gauckler-Manning-Strickler. The application criteria of the two formulae are given and the roughness values are presented in tables

Design of Sewers,d, namely, the minimum and the maximum discharges. The . influences the channel slope and therefore the depositional behaviour, whereas the . establishes the sewer dimensions. A design is flexible if the minimum and the maximum discharges are close. The circumstances however become more difficult fo

Overfalls,ucture has a wide range of application, and many overfall shapes have been suggested until today. The purpose of this chapter is to introduce the main overfall types and to highlight their particular advantages..For ., the standard rectangular and triangular weirs are described. For discharge measur
