Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches
Irrigation and Drainage, EarlyView.ABSTRACT Clogging represents a critical challenge that undermines the efficiency and sustainability of drip irrigation systems by inducing uneven water distribution and increasing maintenance requirements. In this study, the phenomenon of clogging in drip emitters was investigated via computational fluid dynamics (CFD) in conjunction with the discrete ...

Pacific Viewpoint, 1979 Transport in the 1990s has continued the pattern of significant change begun in the 1980s. Rail, sea and air have essentially completed the process towards privatisation, with minimal government involvement in monitoring standards and safety. Roading, however, is still financially confused in its funding and management.
