Consider the following statement for groundwater flow
• The water in confined aquifers is having pressure greater than atmospheric pressure.
• The unconfined aquifer is also known as water table aquifer.
• The unconsolidated type of formation have secondary porosity.
• The perched aquifer is a type of unconfined aquifer.
• Hydraulic conductivity has the dimension of velocity. Choose the correct answer from the options given below:

A soil is having a field capacity of \(42%\) and permanent wilting point of \(19%\). If irrigation has to be done at \(40%\) depletion of available moisture, at what soil moisture percentage the field is to be irrigated?

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The total available water for plant growth (TAW) is the water between field capacity and ultimate wilting point. Reason R: The maximum allowable deficit (MAD) is a part of total available water (TAW) and is usually considered as \(50%\) of TAW. In the light of the above statements, choose the most appropriate answer from the options given below:
• Both A and R are correct and R is the correct explanation of A
• Both A and R are correct but R is NOT the correct explanation of A
• A is correct but R is not correct
• A is not correct but R is correct

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The zone of aeration consists of three belts viz., (1) soil water belt (2) intermediate belt and (3) capillary fringe. Reason R: In the zone of saturation all the macropores are filled with air. In the light of the above statements, choose the most appropriate answer from the options given below
• Both A and R are correct and R is the correct explanation of A
• Both A and R are correct but R is NOT the correct explanation of A
• A is correct but R is not correct
• A is not correct but R is correct

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The clayey soil can retain more water due to more pore space than sandy soil. Reason R: The sandy soil can release more water due to low soil water tension than clayey soil. In the light of the above statements, choose the most appropriate answer from the options given below:
• Both A and R are correct and R is the correct explanation of A
• Both A and R are correct but R is NOT the correct explanation of A
• A is correct but R is not correct
• A is not correct but R is correct

In irrigation, the relationship between water content on mass basis \( \theta_m \), volume basis \( \theta_v \), bulk density of soil \( \rho_s \) and density of water \( \rho_w \) can be expressed as:

In curve number method if \(Q\) is actual runoff, \(P\) is rainfall, \(I_a\) is initial abstraction and \(S\) is storage capacity, then the relationship is shown by:

The hydrograph is useful to estimate:

Using current meter for measuring flow velocity in a stream having depth of \(1 \, \text{m}\), the observation readings should be taken at:
• at \(0\) depth of flow
• at \(0\) and \(0.2\) depth of flow
• at \(0.2\) and \(0.6\) depth of flow
• at \(0.2\) and \(0.8\) depth of flow

If \( n \) is the number of years, \( T \) is recurrence interval in years and \( m \) is ranking of rainfall event, then the recurrence interval given by Weibull formula is:

The following is the non-recording type rain gauge:
• Float type rain gauge
• Symons rain gauge
• Weighing type rain gauge
• Tipping bucket rain gauge
