1. An irrigation canal with trapezoidal cross-section has the following dimensions: Bottom width 2.50 m - 0.90 m (full) - 1.5H to 1V Depth of water Side slope Slope of the canal bed Coefficient of roughness e.001 - 0.025 The canal will serve clay-loam Riceland for which the duty of water per hectare is 3.0 liters/sec. Using Manning's formula, determine the ff: a) Hydraulic radius of the canal, in meters b) Velocity of the water, in m/sec c) Number of hectares served by the irrigation canal

1. An irrigation canal with trapezoidal cross-section has the following v
dimensions:
Bottom width
- 2.50 m
- 0.90 m (full)
- 1.5H to 1v
- 0.001
Depth of water
Side slope
Slope of the canal bed
Coefficient of roughness
e.025
The canal will serve clay-loam Riceland for which the duty of water per
hectare is 3.0 liters/sec. Using Manning's formula, determine the ff:
a) Hydraulic radius of the canal, in meters
b) Velocity of the water, in m/sec
c) Number of hectares served by the irrigation canal
