Character of precipitation during the last 200 years in Prague Klementinum and their impact on water management in the landscape
 Střeštík, Jaroslav
The course of the annual precipitation displays no change over 200 years, only a very slow decline during the 20th century, particularly in its second half. The same, just a little stronger trend holds true for the number of days in each year with abundant precipitation and for percentage of annual precipitation in these days. Therefore, more and more water falls during weak rains instead of the richer ones, which is not favorable for agriculture, because more water evaporates shortly after the rain. In the same period, water flows in major rivers increase, or very little decrease, although precipitation totals are falling more rapidly. Therefore, the proportion of water flowing into the sea is increasing and the proportion remaining in the landscape decreases. All these factors contribute to an intermittent water shortages and an increasing risk of drought occurrence.
