Evaluation of Disaster Management Tasks Related to Hydrological Extremes

Abstract

Although scientific opinions on the effects of climate change predict a long-term decrease in rainfall,  extreme amounts and intensities of precipitation  appear regardless of the seasons and increase the  risk of hydrological disasters. By disasters of hydrological origin generally we mean flood, inland  water, flash flood and drought, and also extraordinary events caused by sudden, heavy  rainfall (for example traffic chaos or damage caused  by drainage malfunction). In Hungary, excess water  and lack of water can cause hydrological damage  even within a calendar year, of which the year 2018 is  a good example.
