Correct answer is (b) Semi Modules

Best explanation: The outlets in the class of semi-modules are those in which the discharge is independent of the water level of the water course but depends only on the water level of the distributary as long as a minimum working head is available. Therefore, the discharge is directly proportional to the water surface level in the distributary.
