Bed level of Canal = + 171.00 m;
Full Supply depth of Canal = 1.60 m;
Bed level of Drain = + 169.20 m;
High Flood Level of drain = 169.20 + 2.50 m = 171.70 m
From the given data,
We can conclude that HFL of the drain is higher than the bed level of canal (171.70 m > + 171.00 m)
and bed level of canal is higher than the bed level of drain, (+ 171.00 m > + 169.20 m)
so the suitable type of cross drainage structure is syphon aqueduct.
