MEASUREMENTS OF SOIL INFILTRATION AND THEIR USE IN EROSION CONTROL

The aim of this paper was to evaluate an infiltration in relation to soil erosion protection control on selected site (Vatin), located in Sazomin cadastral area, at land with permanent grass cover. Measurements took place during the vegetation period May 5th to October 1st, 2009 and were carried out based on field experiments using concentric cylinders. Soil samples were collected after evaluation of hydrophysical properties of the soil. Empirial relation Kostjakov equation was used to evaluate field measurements. The results were processed in the form of tables and graphs. The graphical representation shows the infiltration rate and cumulative infiltration at the selected site. The tables show soil analysis results (e.g. soil density, porosity, instantaneous soil moisture, soil aeration and more). Infiltration capacity is influenced by hydrophysical soil property values, it is mainly dependent on immediate soil moisture which is affected by precipitation and by porosity depending on soil compaction. Sown grass vegetation performs its function as a protection against soil loss e.g., torrential rainfall and subsequent water erosion.
