b) Curved section (Figs. 7 & 8)
This consists of determining the curves of the canal. The criterion is to
obtain a smooth and symmetrical curve so that the water flows as
smoothly as it does in the straight section.
1. Take a distance L“ ” from the PI towards the left and the right,
determining points a and b.
2. Determine points c, d, e, placing a taught rope between a and b.
Then take distance m“ ” perpendicular to the PI with the rope. Points
c, d, e are then located at:
D = m/2 c = e = 4 (2)
