Which of the following statements regarding construction and installation of weirs are true?
(A). The velocity of approach of water to the weir should not be considered.
(B). Weir crest should be placed closer than 2H from the bottom of the channel.
(C). The head over the weir should be measured on the upstream side at a distance of at least 4 times the head of flow from the weir.
(D). The falling water surface from the weir should not have free flow.

Choose the correct answer from the options given below:
An error of 1 % in measuring head (H) will produce
