Comparison of two methods of phosphorus transport modelling in large areas

Popis výsledku v původním jazyce

Water erosion is a natural process of soil surface disturbance by rainfall and surface runoff. Phosphorus transported by surface runoff is followed by eutrophication of water bodies and water quality issues. The problem rises with climate change and increasing climate extremity. Agriculture soil, infrastructure and water quality protection have to be ensured by suitable legislative measures. The efficiency of these measures can be proved by suitable mathematical modeling of the soil erosion and nutrienttransport to watercourses and water bodies. This article presents the comparison between the indirect determination of the transported dissolved phosphorus using the equation of Sharpley (1995), based on usually used enrichment ratio and assumed share of the dissolved phosphorus in the total transported phosphorus during erosion event, and the direct determination of the transported dissolved phosphorus amount, based on the newly derived methodology. Study areas (four catchments of doze
