Effects of drainage treatment and stand growth on changes in runoff components from a forested watershed

Popis výsledku v původním jazyce

Runoff generation under various natural conditions has often been studied in forested watersheds for a long time. In 1967, Hewlett designed a variable source area model. The model is based on the expansion and shrinkage of variable source areas and consequent changes in a drainage network during a discharge event. The runoff investigation was carried out in a forested watershed situated in the summit area of the Orlické hory Mts. Runoff components, their amounts and ratios were calculated using a simplegraphical-mathematical method of the hydrograph recession limb analysis according ro a reservoir model representing the particular components. Comparing the amount of slow and rapid runoff constituents, the greater amount of slowly moving water confirmed that overland flow was absent under conditions of forest environment. Not even the drainage treatment altered this positive ratio of the runoff constituents.
