Question

Due to inadequate drainage which factor causes waterlogging with constant percolation?

(a) Over and Intensive Irrigation

(b) Impervious Obstruction

(c) Inadequate Surface Drainage

(d) Flat Topography

The question was asked in an interview for internship.

My query is from Causes of Water-logging topic in section Water Logged Reclamation and Saline Soils for Agricultural Purposes of Irrigation Engineering

Answer 1

Right option is (c) Inadequate Surface Drainage

Explanation: During rains storm water gets mixed with irrigation water. The irrigation water should be removed so as to not mix with storm water as this leads to percolation. Moreover, if proper drainage is not present constant percolation happens and water table rises.
