Abstract
Soil water content is very important for agricultural practice. Direct measurements of the soil moisture are being replaced by mathematical simulations and models step by step. One of the most used models for the simulation of the soil moisture is HYDRUS 1D model. This paper deals with HYDRUS 1D validity check in the Nitra River Catchment. Three different localities in the Nitra River Catchment (Malanta, Kolíňany and Dolné Naštice) were chosen for model validity check. Both, measurements and modelling of soil moisture, were made for these localities in three years (8/2011 - 8/2014). The evaluation of model validity was performed by calculation of the correlation coefficient and count of comparisons with variance of 15%. The correlation coefficients of measured and simulated data were between 0.67 and 0.95. Data comparisons with variance of 15% among measured and simulated data were between 79 to 100%. Based on these results we can declare that HYDRUS 1D model is valid for the conditions of Slovak catchments.
Keywords: HYDRUS 1D, soil moisture, simulation, model validation
