Introduction Changes in land use and agricultural management have caused a strong increase in sediment and particulate phosphorus input into the Miyun reservoir. The simulation of the relevant runoff and sediment fluxes at the mesoscale needs adequate procedures, adapted to a semiarid monsoon climate and regional land-use pattern. Results The modified Universal Soil Loss Equation (USLE-M) was integrated...
Mit einem Kompartimentmodell wird für ein 800 km2 großes Testgebiet in Nordsachsen die grundwasserbürtige Nitratbelastung der Fließgewässer in der Mesoskala räumlich differenziert berechnet. Hierzu werden sowohl ein Emissions- als auch ein Immissionsansatz herangezogen. Die Abbildung des Stofftransports erfolgt auf der Grundlage des Geschwindigkeitsfelds eines als zusammenhängend angenommenen oberen...
