The article deals with the analysis and assessment of climatic and hydrological drought risk for selected territories of the Czech Republic based on the data provided by the Czech Hydrometeorological Institute for the past ten years. Climatic data consisted of the average monthly temperature and the average monthly total sum of precipitations from the selected territory. The hydrological data of the territory under observation comes from ten shallow underground water wells, one deep water well and one water meter station on the watercourse. A linear regression analysis method was used to analyse drought risk data. The null hypothesis was verified to determine the relationship between the two variables using regression analysis. Two normality tests (Kolmogorov-Smirnov test and Shapiro- Wilks test) were used to verify the regression analysis model. The results of the development of climatic data in the territory show that the temperature and precipitation trend is worsening with the tendency to cause deeper climatic drought in the territory.
