Investigation of infiltration in Center Pivot irrigation system
Use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. In this study the infiltration parameters were evaluated in real conditions of a center pivot system. For this purpose a single ring...
متن کاملDynamics of Water Vapor Content around Isolated Sprinklers: Description and Validation of Model
Irrigation consumes considerable water to satisfy the current food demand. An improvement in water use efficiency for irrigation is essential. Wind drift and evaporation losses reduce the water use efficiency of center pivot irrigation systems in arid and semi-arid areas. In this paper, a model of water vapor dynamics during and after overhead sprinkler irrigation was developed and validated by...
متن کاملComparison of Water Distribution Characteristics for Two Kinds of Sprinklers Used for Center Pivot Irrigation Systems
Sprinkler selection influences the water distribution uniformity of center pivot irrigation systems. The sprinkling uniformity of the center pivot is crucial for the yield and quality of crops on a large scale. Rotating and fixed spray plate sprinklers (RSPSs and FSPSs) are the two most popular types. However, sprinkler selection is mainly based on price, not on differences in performance betwe...

The objective of this research was to determine the influquire relatively large amounts of energy to develop ence of center-pivot sp...
متن کاملEffect of the Start-stop Cycle of Center-pivot
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...
