Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several irrigation t...

center pivot irrigation system is used as a modern irrigation method in different parts of iran. unfortunately due to lack of proper design and hydraulic shortcomings of the system in several agricultural lands in iran, the efficiency of the center pivot irrigation system is low or unacceptable. low system efficiency results in non-uniformity of water distribution along the lateral and on the c...

the variety of sprinkler devices available for the center pivot and linear irrigation systems has been increased dramatically in recent years. in the current study, via conducting some indoor experiments, one type of fixed pad spray sprinkler (d3000) and two types of moving pad spray sprinklers (r3000 and s3000) with various configurations (working pressure, nozzle size and type of deflector pa...

8 The modernization of irrigation districts in Spain is based on the construction of 9 collective pressurized networks equipped with remote control systems. In this paper, a 10 simulation approach is used to explore the benefits of introducing a collective solid-set 11 irrigation control software. The controller works in combination with a district 12 management database, real time evapotranspi...

27 28 The simulation of center-pivot performance has been the subject of research 29 efforts since the 1960s. Center-pivot models frequently use empirical equations 30 relating pressure and sprinkler radial application pattern. Individual, stationary 31 water application patterns are overlapped and the resulting water application is 32 mapped in the field. Such models use constant tower angular...

Abstract Nowadays, the development of irrigation is increasingly recognized as a necessary factor in agriculture, primarily because global warming. Depending on field conditions, most commonly used method sprinkler irrigation. The spray uniformity sprinklers installed equipment can be characterized by Christiansen-uniformity coefficient (CUc%) and distribution (DU%). Our investigations were car...
