Progress till now… Selecting suitable foundation. Learned to analyze all the components

using staad.pro software. Learned to design all the components

of bridge using Manual means in working stress method.

Calculations LWW• Depth of water (d) = 2.79 m• Assumed afflux (H) = 0.15 • Velocity of approach (Va = V x d/(d+H)) =

2.183 m/sec • Head due to velocity of approach (Hva =

Va2/2g) = 0.244 m • Total head (Ht =H + Hva) = 0.394 m • Velocity through vent (Vv = (2gHt)0.5) =

2.781 m/sec

Calculations LWW• Linear waterway required (Q/( Vv x d))

= 544.208 m • Proposed Span arrangement = 27 x

21.6 m = 583.2 - 26 - 1.5 = 555.7 m• Linear waterway provided = 555.7 m >

544.208 m • Hence Okay
