Hydrochemical load in a small river following heavy rain events

Kändler M., Seidler C., 2009, Hydrochemical load in a small river following heavy rain events, Folia Geographica ser. Geographica-Physica, vol. XL (40): 27-32.

Keywords: erosion, suspended load, nutrients, heavy metals

Summary: The paper focuses on the concentration of selected chemical substances during flood events in a stream situated in the hilly region of Oberlausitz in Saxony (Germany). The stream's catchment (27 km2) is strongly influenced by human activity (11% urban areas, 70% agricultural areas). Water pollution is mainly caused by diffuse sources. The soil erosion from arable land leads to suspended load in the stream. Runoff from paved surfaces and roofs transports particularly heavy metals into bodies of surface water.
Suspended load was determined indirectly via continuous turbidity measurements (Ysi 6136) as well as directly by taking water samples depending on discharge. The samples were analyzed in the lab in order to obtain the mass of suspended particles by filtration, drying, and weighing. The concentrations of selected nutrients and heavy metals were also determined. As expected, during the spring season with bare or partly covered soil, particle concentration in streamwater was high following heavy rainfall events. The maximum concentration of suspended particles occurred shortly after the discharge peak. One rain event in May 2007 with a maximum intensity of 13.6 mm in ten minutes resulted in a suspended particle concentration of 38 mg?dm-3 and a total delivery of 200 t throughout the entire flood event. Heavy metal concentrations attained their maxima before all other chemical species during this flood event. A lower intensity rain event in April 2008 produced delayed concentration peaks compared to maximum discharge. Zinc, cadmium, lead, antimony, and aluminum concentration exhibited similar behaviour depending on discharge. In this study copper was chosen as an example.
