• For a canal which irrigate the area directly, the fall should be provided at a location where the F.S.L. outstrips the gound level, but before the bed of the canal comes into filling.
• When the levels are such that the F.S.L. of the canal is much above the bed level of the drainage trough, so that the canal runs under syphonic action under the trough, the structure provided is known as
• In level crossing, the water level of canal is much higher than that of the drainage.
• The drainage water intercepting the canal can be disposed of by passing the canal below the drainage in
• If the R.L's of canal bed level and high flood level of drainage are 212.0 m and 210.0 m respectively, then cross drainage work will be
• When the full supply level (F.S.L.) of the canal is much below the bed level of the drainage trough, then the cross drainage provided is called syphon aqueduct.
• When the bed level of the canal is higher than the highest flood level (H.F.L.) of the drainage, then the cross drainage work is said to be
