Exam 9: Irrigation and Hydraulic Engineering

The knowledge of hydrology is necessary in civil engineering for

The borrow pits should, preferably, be taken from

The duty is largest

The duty at outlet is called capacity factor.

Rivers on alluvial plains may be

The main cause of silting in channel is

A canal sligned nearly parallel to the contours of a country, is known as

When the irrigation canal and the drain are at the same level, then the cross drainage work is achieved by providing a

The basic factor which controls the process of meandering is

In Bligh's creep theory, it is assumed that the percolation water creep

The water shed canal is also called

For closed growing crops (such as wheat), the method of irrigation used is

Liquid precipitation consists of

In a flexible outlet, the discharge depends upon the

The ratio between the area of a crop irrigated and the quantity of water required during its entire period of the growth, is known as

The loss of head per unit length of creep is called

The amount of precipitation is measured by

The irrigation engineering may be defined as

The function of a barrage is different to that a weir.

The crest of the under-sluices should be lower than the crest of the head regulator (if silt excluder is provided by at least
