description: The theme of the final qualifying work is Â«Mathematical model of hysteresis of soil water retention capacity as a theoretical basis for consideration of hydrological conditions to calculate precision irrigation ratesÂ». Objects of the research are soils; the subject is a hysteresis of the water retention capacity of the soil.
In this work computational experiments were carried out using data from the literature on the hydrophysical soils properties of different particle size distribution. The error analysis of the point approximation of the main branches and the predictive the scanning branches were performed. Precision irrigation rates and dewatering coefficient calculated.
