摘要

In efficient utilization of irrigation water resources, it is very important to determine dimension diameter (d) and depth (z) of wetted soil (wetting onion) at different times from commencement of irrigation (t). In this research, by utilization of physical factors effective in volume of wetted soil under point feeding source and by use of the Buckingham ∏ theorem and dimensional analysis, some dimensionless numbers were defined. Then the relations obtained by dimensional analysis were compared with laboratory data collected from a physical model. At last, a number of scientific-experimental equations were obtained that showed a good agreement with the experimental results. This indicates that the derived empirical functions could be used properly for designing drip irrigation system.
