Název v původním jazyce

Monitoring of soil erosion by water in multiple scales

Popis výsledku v původním jazyce

At Faculty of Civil Engineering, Czech Technical University in Prague, soil erosion models were applied since 1950 and verified by various measurements. Recently the Department of Irrigation, Drainage and Landscape Engineering focused on several scales of soil erosion monitoring. Splash erosion is monitored within project No. GA17-33751L, where several sites and soils are compared. Larger scale is provided by monitoring on 16 m2 plots under natural and synthetic rainfall. Our contribution will mainly present the third measure scale of monitoring soil erosion processes and its development, which is the monitoring of whole agricultural parcels or river basins. CTU monitoring is carried out on several locations. Finally, three new sites are being monitored. Research in these new localities focuses on providing input data on existing erosion threats on agricultural fields and it is based on continuous monitoring set in place in 2018. This monitoring consists of a number sub-tasks, which are: - field survey and on-foot monitoring of current state and evidence of erosion; - establishing the basic hydropedological characteristics of the monitored localities; - identification of suitable profiles for long-term erosion monitoring; - initial RGB RPAS monitoring; - securing and primary analysis of suitable satellite data; - target the volume of sediment in selected reservoirs within monitored localities; - establishing a long-term monitoring of the hydrological regime of the soil; So far, we managed to do and process several UAV flights, estimate the extent of rill erosion, do a hydropedological survey and its link to soil properties modified by erosion processes and establish continuous monitoring of soil humidity regime. The monitored sites are affected by a long-term erosion. The research is supported by project of Ministry of Agriculture of the Czech Republic No. QK1720289, and project No. SGS 17/173/OHK1 and by project No. GA17-33751L.
