The research focuses on the potential interception that describes the amount of maximum storage capac− ity of the plant surface. The study regarded trees interception under simulated rain in the range of 2 to 11 mm/h. Non−linear model was proposed for estimation of the analysed parameter. Interdependence of potential interception and the intensity of rain and the size of droplets was described using exponential equation
The concept of potential interception is used to determine maximum amount of water that can be retained by the surface of all parts of a sprayed tree. The word ‘potential' is supposed to emphasize the fact that ‘maximum interception' is not a constant value. For each individual rainfall it may assume a different value. Potential interception values depend each time on rainfall intensity and drop size. Nevertheless, formulas describing the influence of species specifics of trees and other characteristics of surface are still being searched for. It is also being indicated that some characteristics may demonstrate a certain dynamics related to time of exposure to factors capable of modulating these characteristics.
