Runoff and Soil Erosion Formation on Small Arable Catchment

Popis výsledku v původním jazyce

The aim of the contribution is to examine the runoff dynamics on a small catchment scale with respect to variable hydraulic properties of the topsoil. The conceptual model assumes two possible mechanisms depending on the actual topsoil structure. (a) After the tillage soil contains stable aggregates with hydraulically conductive inter-aggregate voids. Water percolate through the preferential pathways towards compacted subsoil layer, where lateral interflow is formed. The hypodermic runoff is the most common form of the catchment drainage during these periods. (b) During summer when the topsoil is already compacted, ratio of the preferential pathways is small and surface soil crust is present, the catchment is prone to surface runoff.
