Denehy's groyne is a special type of groyne which is

Which of the following is not a type of controlled flooding method?

A crop requires a total depth of 92 cm of water for a base period of 120 days. Find the duty of water.

What is the maximum vertical stress (N/m²) acting on a dam if the sum of the net vertical force per unit length is 10500 N/m and the width of the dam is 60 m with an eccentricity of 15 m?

A dam with an ogee spillway has a total head on the crest of 4 m and an effective crest length of 85 m. The coefficient of discharge is 2.3. Calculate the discharge capacity of the ogee spillway.

In a gravity dam, the maximum stress on the soil at the toe is 5 MPa, and the slope on the downstream face of the dam is 0.65 horizontal to 1 vertical. If there is no tailwater, find the maximum principal stress at the toe.

What are the recommended setting options of an adjustable proportional module worked with an open flume type outlet?

1). 3/10
2). 9/10
3). 1/2
4). 5/3

Given that a particular irrigation field has a Culturable Command Area (CCA) of 200 hectares, out of which 150 hectares of land is cultivated for the rabi season and 100 hectares of land is cultivated for the kharif season, what is the intensity of irrigation for each season?

The field capacity and permanent wilting point for a given 0.8 m root zone soil are 35% and 10% respectively. At a given time, the soil moisture in the soil is 20% when a farmer irrigates the soil with 250 mm depth of water. Assuming the bulk specific gravity of the soil is 1.6, determine the amount of water wasted from the perspective of irrigation. (Assume the plan area of the soil in the root zone to be 1 m²)

The moisture content of soil in the root zone of an agricultural crop at a certain stage is 0.05. The field capacity of the soil is 0.15. The root zone depth is 1.1 m. The consumptive use of the crop at this stage is 2.5 mm/day, and there is no precipitation during this period. The irrigation efficiency is 65%. It is intended to raise the moisture content to the field capacity in 8 days through irrigation. The necessary depth of irrigation is (γd = 1.5).
