Quantifying Water Pollution Sources in a Small Tile-drained Agricultural Watershed

Popis výsledku v původním jazyce

This paper evaluates the quantityandqualitydynamics of surfaceanddrainage waters in a small, 7.1km2 agricultural watershed, located in the crystalline complex of the Czech Republic. Concentrations and monthly solute loads of amonium nitrogen (NH4-N), nitrate nitrogen (NO3-N), phosphate phosphorus (PO4-P) and total phosphorus (Ptot) from ten watershed?s subcatchments with different soil, land use and tile drainage characteristics were compared for the period March?October from 2009 to 2011. The results and relevant processes were described using regular monitoring as well as event-based sampling approaches, methods of runoff separation and regression techniques. The average baseflowcomprised 35?50%, whereas interflowandoverlandflowwere50?65%of the totalrunoff. The highest concentrations of NO3-N were detected in waters originating from cultivated and tiled subcatchments; those of NH4-N, PO4-P and Ptot came from subcatchments containing settlements and water ponds. In the monitored site
