Experimental evaluation of the effect of the protective technical measures against rill erosion

Original language description

The embankments along the roads, railroads, watercourses and other linear structures are very often not protected against the soil erosion during the construction works and also operation phase. In the conditions of the Central Europe the earthworks stage usually overlaps with the period of sudden heavy rainstorms with very high erosivity factors. This causes mobilization of large amounts of soil from the construction sites to the surrounding environment. The sediment, often enriched with bounded pollutants, causes siltation and pollution of the nearby watercourses and reservoirs. We present an ongoing research project that investigates the quick and easy technical measures that have a potential to protect the slopes against the splash erosion, rills development and the topsoil sliding. The specific goal is the experimental testing of various mechanical and technical surface protection measures and evaluation if it’s effectivity. In the first stage of the research we test covering of the slopes with different permeable materials. The experiments are done on the 6 m long inclined plots with different inclination. The plots, encapsulated in large steel containers, are equipped with a nozzle rainfall simulator, with sediment and runoff collection system and with soil water regime and temperature regime monitoring. We compare the runoff, soil loss and surface topography changes (sliding, soil compaction and rills development) on the protected and untreated plots. The research is funded by the Technological Agency of the Czech Republic (research project TH02030428) and an internal student CTU grant.
