Papenmeier, S., Schrottke, K., Bartholomä, A.. Total volume concentration and size distribution of suspended matter at sites affected by water injection dredging of subaqueous dunes in the German Weser Estuary.

Zusammenfassung: A laser based in-situ particle sizer (LISST) was used to analyse spatial and temporal variability of total volume concentration (TVC) and particle-size distribution (PSD) of suspended particulate matter (SPM) during water-injection dredging (WID) of subaqueous dunes in the German Weser estuary. Ground-truthing was done by water sampling. Investigated WID sites are located in the brackish and freshwater zone, respectively. Measurements were conducted in June 2008, during neap tides and low river-discharge. TVC of SPM is tidal controlled. Site-specific differences of SPM amount and sizes are recognisable, but dredging impact is hardly visible in the data.
