Quantification of Soil Water Balance Components During the Vegetation Period in 2018

Hydrological processes in the atmosphere – plant cover – soil aeration zone – groundwater system are most affected by global climate changes, which influence the distribution and intensity of rainfall. These changes need to be monitored and forecasted for their future development, which is of great importance for human activities, especially agriculture and forestry. Data for the evaluation of soil water regime are obtained from field monitoring. Interpretation of temporal and spatial movement of water in the aeration zone is made by constantly improving computing techniques using various algorithms applied in mathematical simulation models. In our work we used the GLOBAL software, developed at the Institute of Hydrology of SAS, to simulate the individual components of the water balance in rigid soils in the locality Milhostov (Eastern Slovakia Lowland). The paper aims to quantify water balance components of a given soil system. Numerical simulation results were compared with data obtained from field monitoring during the vegetation period in 2018.
