Description
| - The aim of the study is to explain the runoff formation and confirm validity of our conceptual model of quick runoff generation on inclined cultivated soils. Within former observations a compacted subsoil layer was identified, which could significantly contribute to quick runoff response even during low-intensity rainfall events. Using a mobile rainfall simulator the 16 m2 inclined experimental plot was successively exposed to artificial rainfalls with intensity and duration ranging from 23 to 64 mm/hour and from 60 to 155 minutes respectively. The dynamics of surface and shallow subsurface runoff and soil water regime in three depths were monitored. Various initial soil moisture conditions as well as vegetation stages from cultivated fallow to stubble delimited the simulations. In relation to rainfall intensity and duration variable proportions of both monitored runoff components were observed, ranging from zero surface runoff to its distinct dominance. Both components interacted very fast, shallow subsurface runoff was always formed first and in most of the simulations it appeared with equivalent intensity to surface runoff. In two last simulations both components reached the quasi steady-state conditions, the subsurface runoff intensity ranged from 50 % to 75 % of the surface runoff peak value. So far the results and observed processes confirm the proposed conceptual model of runoff formation and emphasize the important role of preferential flow and lateral shallow subsurface runoff.
