If 24-hour excess rainfall to be impounded in 1m width of land between two consecutive contour bunds with a vertical interval of 2 m is 1 cm, then what will be the depth of impounding near bund?

Followings are some of the statements related to drop spillway
(A). Drop spillway should be located on a reasonable straight section of channel with no upstream and downstream curves within 50 m reach of the structure.
(B). Transverse sill create a hydraulic jump at the toe of the structure.
(C). Longitudinal sill helps to straighten the flow.
(D). The cutoff wall depth should be sufficient to increase uplift pressure and reduce piping under the structure.
Choose the correct answer from the options given below:

Which of the following stream bank control measure is used especially when stream takes a sharp bend and bed scour is not deep?

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): In strip cropping both close growing and row crops are planted in alternate strips in the same field.
Reason (R): In comparison to contour farming, strip cropping is a more effective method to control erosion.
In light of the above statements, choose the most appropriate answer from the options given below.

Followings are some of the statements related to farm pond
(A). Dugout ponds are the most common type of farm ponds.
(B). Levee ponds are generally used in aquaculture.
(C). A narrow section of valley with mild side slopes are preferable for pond site selection.
(D). Simpson's rule gives more accurate capacity of pond values than the trapezoidal formula.
