| Zusammenfassung |
| This paper examines sediment and metal (Al, Fe, Mn, Cu, and Zn) exportation
at different timescales (annual, seasonal and event) during a 3-year
period (2005–2008) in the Mero River headwater, a rural catchment under
humid temperate climate. Interannual differences were found both in annual
loads and their distributions throughout the year. At annual scale, sediment
and particulate metal loads followed the same trend as streamflow, while
dissolved metals showed different patterns. Runoff events contributed to 63% of the total sediment load, whereas particulate and dissolved loads in
events accounted for between 38–61 and 27–49%, respectively. Runoff
events were characterized by high variability in sediment and metal loads, a
few events representing a high percentage of the metal exported. Sediment
loads were related to maximum and initial discharge. Particulate metal loads
were highly correlated with sediment loads, runoff being the hydrological
variable that best explains the load of these metals. Dissolved metal loads
displayed different patterns. Dissolved Al, showed a great correlation with
runoff, while dissolved Mn with maximum discharge. |
