It is defined as the depth (or amount) of water needed to meet the water loss through evapotranspiration.

Which is NOT a factor affecting the water requirement?

The whole area enclosed between an imaginary boundary line which can be included in an irrigation project for supplying water to agricultural land by the network of canal.

The area where agriculture cannot be done, and crops cannot be grown.

The area where agriculture can be done satisfactorily.

The total area within an irrigation project where the cultivation can be done, and crops can be grown.

Is defined as the ratio of the cultivated land for a particular crop to the culturable command area.

The ratio of the number of days the canal has actually been kept open to the number of days the canal was designed to remain open during the base period.

The ratio of the average discharge to the maximum discharge.

The period during which some particular crops can be grown every year on the same land.

The process of changing the type of crop for the cultivation on the same land.

It is defined as the total period from the sowing of a crop to the time of harvesting.

It is defined as the ratio of the areas of the two main crops.

The quantity of water flowing continuously for one day at the rate of one cumec.

It is reshaping of the field surface to a planned grade. It is necessary in making a suitable field surface to control the flow of water, to check soil erosion and provide surface drainage.

It is the removal of abrupt irregularities such as dunes and rings, filling of pits, depressions and gullies.

It consists of removing of some or all the trees, vegetations, trash and boulders from the area specified for land grading.

It refers to a broad class of irrigation methods in which water is distributed over the field by overland flow.

This method makes use of parallel earth rides to guide a sheet of flowing water across a field.

A type of irrigation that avoids flooding the entire field surface by channeling the flow along the primary direction of the field using 'furrows system.

In this type of irrigation, water is put into pipes, pressurized and precisely delivered to plants. This method saves much more water than traditional surface flow irrigation.

It is a method of applying irrigation water which is similar to natural rainfall.

It is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates.

These are engineering constructions designed and mechanically fit for managing and utilizing water resources to the best advantage of the human being and environment.

It is a barrier across flowing water that obstructs, directs or retards the flow, often creating a Reservoir.

It is an artificial lake created by flooding land behind a dam.

These can be defined as dams constructed of natural materials excavated or obtained from the vicinity of the dam site.

It is the most ancient type of embankments, as they can be built with natural materials with a minimum of processing and primitive equipment.

The embankment is constructed in successive, mechanically compacted layers.

It is the vertical distance between the maximum reservoir level and the top of the dam.

The method used for examining the stability of slopes of earthen embankments is called ___.

In slope stability, the earth mass is divided into a number of vertical segments called ____.

In mohr-columb analysis, (phi) represent what parameter?

Which one is NOT a cause of failure of earth dams?
