Analysis of spatio-temporal variability of soil erodibility values by water erosion

Original language description

In current dynamic development of GIS and remote sensing methods, especially the use of accurate LiDAR data, there is a significant disproportion in the accuracy of morphological and soil data in the assessment of erosion. In current practice, the map of main soil units (MSU) is used to determine soil erodibility (expressed by K factor), which in many cases lead to a step change in values within one field or erosion closed unit (ECU). However, the soil properties included in the calculation of the K factor usually change smoothly in the direction of the slope, but also due to other morphometric characteristics. Terrain morphology should therefore be taken into account when determining the K factor values. The K factor values change dynamically both according to the terrain morphology within ECU and depending on climatic conditions that change during the year and within the geographical location in the Czech Republic (CR) and given physio-geographical conditions. In assessing the seasonal dynamics of K factor values, they appear to be key erosion rainfalls. By including this spatio-temporal variability of K factor values, it will be possible to significantly refine soil loss calculations and proposals for erosion control measures and retention elements and their intangible services for environment and increasing the landscape character and recreational potential of the site.
