<jats:p xml:lang="en">Runoff from forests predominates above runoff from adjacent agricultural and other land-use types during longer periods of climatic drought. The predominating forest runoff is 180 days per year, in average. There are streamflows of 180–366-day by 10-year average. To practical proving this hypothesis, the runoff study was done for upper part of the Svratka catchment with measuring profile in Dalečin, the Czech-Moravian Highlands. The catchment was segmented into four land-use types: 43% of forest stands, 29% of agricultural crops, 20% of permanent grasslands, and 8% other lands. Besides forest influence on streamflow directly in the Svratka River, the runoff from other land-use types of the agriculturalforestry catchment was also calculated. It was proved that greater runoff drained from the forest than from the remaining land uses of the catchment. The 43% share of the forest in the upper Svratka catchment increased during climatic drought mean runoff in by 6.2%.</jats:p>
