Linear trends for the multi-year period 1961-2014 indicate stagnation or a slight increase in the amount of rainfall on the entire territory of Bosnia and Herzegovina. Changes in the amount of rainfall are more pronounced by seasons than annually. In the central part it is negative during spring and summer (and most pronounced in the area of Herzegovina -up to 20 per cent), while during autumn increased rainfall was observed, especially in the northwestern and central parts. Due to the increased intensity of rainfall and its greater variability, as well as the increased share of heavy rains in the total amount of rainfall, there is increased risk of flooding, especially in the north-eastern part of the country, where the most disastrous floods in history were recorded during May 2014.
