why in induction Canal are been used in irrigation purpose
Answers
Explanation:
It also serves the purpose of improving the traffic ability of farms for farm machinery etc.The field drainage system is generally sub-surface.In arid zone the function of drainage is to prevent irrigation induced water logging and salinization of soils.An irrigation canal is a hydraulic system whose main objective is to convey water from a source (dam and river) to different users. Such systems can be very large (several tens or hundreds of kilometers); they are characterized by time delays and nonlinear dynamics, strong unknown perturbations and interactions among subsystems. Varying operational objectives are assigned to their managers. The main general objective is to provide water to the different users at the right moment and in the right quantity, reducing losses as much as possible in order to guarantee the safety of the infrastructure. In particular, a major concern is to prevent the canals from overtopping, and also from having water levels inside the pools below the supply depths of the gravity offtakes
