Abstract
The aim of this study was to determine trends in gauging stations in Slovakia. We investigated 487 stations during the period 1981-2013. Monthly rainfall trends were detected by non-parametric Mann-Kendall statistical test. Precipitation trends show high variability. The precipitation time series in Slovakia in gauging stations in particular have an increasing trend, especially in the month of July. Achieved results can be the basis for the development of river basin management plans and within the framework of risk assessment they will address all aspects of environmental risk management focusing on prevention, protection, preparedness (including forecasts and early warning systems) and taking into account the characteristics of each river basin. It is highly desirable but also feasible to limit the risk of adverse consequences, especially for human health and life, the environment, the cultural heritage, the economic activity and the infrastructure associated with extreme hydrological phenomena in the river basins. However, measures to reduce these risks if they are to be effective must be as far as possible coordinated throughout the river basin.
