The objective of this study was to evaluate the hydraulic pressure gradient along lateral line microsprinklers, using Wu and Gitlin model. Mathematical simulations were developed in an electronic spreadsheet Microsoft Excel software (2016). Where adapted equation Blasius model determined, energy line, length (L), number emitters (N), adjusted (Lajst), fitted (Najst), flow velocity (m² s-1) loss...

For over 30 years, attempts have been made to determine when to begin treating for walnut blight, Xanthomonas campestris pv. juglandis. Past trial results have always indicated that the best time to begin treating was just before significant moisture, usually in the form of rain, occurred. Without some control over the amount of moisture present, the time to begin treating could not be tied to ...

Droplet shear stress is considered as an important indicator that reflects soil erosion in sprinkler irrigation more accurately than kinetic energy, and the effect of droplet impact angle on cannot be ignored. In this study, radial distribution angles, velocities, stresses were investigated using a two-dimensional video disdrometer with three types low-pressure (Nelson D3000, R3000, Komet KPT) ...

Porous pavements with reservoir structure for infiltration of runoff from parking spaces and residential streets offer the opportunity to dispose water without using additional space in urban areas. However, pollutants in urban runoff endanger soils and groundwater, when pollutant retention in the structure is not sufficient. Porous pavement structures with four different subbase materials were...

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...
