Question

When a canal is taken as an example what factor about it causes waterlogging?

(a) Seepage of Water from the High Lands

(b) Seepage of Water through the Canals

(c) Over and Intensive Irrigation

(d) Excessive Rains

I got this question during an online interview.

The origin of the question is Causes of Water-logging topic in portion Water Logged Reclamation and Saline Soils for Agricultural Purposes of Irrigation Engineering

Answer 1

Right option is (b) Seepage of Water through the Canals

To explain: When a canal is unlined then there room for seepage losses through the side slopes, and bed of the canal. This leads to the rise of water table in the adjoining areas due to percolation of water, which ultimately leads to waterlogging.
