Question

What is the approximate value of side slope of the bund for smaller tanks with water depths not exceeding 2.5 m in favorable soils such as red and white gravel, red and black loams?

(a) 2 H : 1 V

(b) \(\frac{1}{2}\) H : 1 V

(c) 2 \(\frac{1}{2}\) H : 1V

(d) 1 \(\frac{1}{2}\) H : 1 V

This question was addressed to me in examination.

Asked question is from Tank Irrigation in section River Navigation & Tank Irrigation of Irrigation Engineering

Answer 1

The correct option is (b) \(\frac{1}{2}\) H : 1 V

Explanation: For smaller tanks with water depths not exceeding 2.5 m in favorable soils such as red and white gravel, red and black loams, the side slope may be taken as \(\frac{1}{2}\) : 1 and 2 : 1 for larger ones up to 5 m in depth. The slopes may be kept in between 2 : 1 and 2 \(\frac{1}{2}\) : 1 in light sandy, black cotton or clayey soils.
