ANALYSIS OF INFLUENCE OF NEW IRRIGATION FACILITIES AND METHODS ON WATER DISTRIBUTION OPERATION PROCESSES (overwiew)

Topics: 06.01.02 Land Reclamation, Recultivation, and Land Protection

Abstract:

The aim of the research was to perfect the theory of water distribution management in irrigation systems using newly developed means and methods of irrigation. The conclusion was drawn that the emergence of new opportunities in modern sprinklers as well as the increasing use of low-water irrigation methods, also determines the appearance of new types of disturbances affecting the work of irrigation systems that have not been previously considered in the theory of water distribution. It is shown that, in some cases, it can lead to emergencies in the water distribution network and, as a consequence, to unproductive losses of irrigation water or even emergencies. Analysis of the operation of sprinklers in the Zone Control mode revealed that the possibility of programmable control of sprinkler valves in this mode, on the one hand, allows controlling the irrigation norm, but, on the other hand, leads to an uncontrolled disbalance between the amounts of water supplied by the water distribution system, and water withdrawn for irrigation. Analysis of the Speed Control option which allows controlling the irrigation rates by changing the speed of the sprinkler, showed that in some cases this can lead to conflicts connected with incorrect positioning of the sprinkler on water distribution system and, as a consequence, to the wrong definition of lag time and dissynchronization of costs and expenses. It is also shown that the use of drip irrigation systems ensuring the economical use of irrigation water during irrigation at the same time can lead to its possible unproductive losses in water distribution network due to the engineering impossibility of matching the amounts of costs and expenses therein. Conclusions are drawn that the use of new irrigation methods and their capacities should be organizationally and technically linked with the existing capabilities of water distribution systems, delivering water to them and be accompanied by the improvement of algorithms and means of water distribution management.
Key words: irrigation systems, irrigation methods, sprinkler machines, drip irrigation, water consumption, water delivery, water distribution network, water distribution management.
