Calculate the water surface profile through Zones 1 and 3 using the (see Chapter 7) with consideration of expansion and contraction losses. The table 9-1 below provides recommended loss coefficients.

Table 9-1: Recommended Loss Coefficients for Bridges

Transition Type	Contraction (K c )	Expansion (K e )
No losses computed	0.0	0.0
Gradual transition	0.1	0.3
Typical bridge	0.3	0.5
Severe transition	0.6	0.8
