Particle transport in lakes: Models and measurements
Open accessAbstract
Results of experimental measurements and mathematical modeling demonstrate that coagulation in lakes can be sufficiently rapid and extensive to affect suspended particle concentrations and sedimenting fluxes significantly. The process dominates particle removal in Lake Zürich and substantially influences particle concentrations in the water column of Lake Sempach. Natural coagulation in lakes is a process that is strongly influenced by solution chemistry. Calcium ions act as destabilizing agents and enhance natural coagulation while dissolved natural organic matter stabilizes particles and retards coagulation. Since solution chemistry varies widely among lakes, natural coagulation rates are expected to differ among lacustrine systems. Field observations of Lakes Zürich and Sempach support this view. Although primary productivity in Lake Zürich is considerably lower than in Lake Sempach, higher sedimenting fluxes are observed in Lake Zürich. The waters of Lake Zürich are low in dissolved organic carbon, permitting rapid coagulation in the epilimnion of the lake and producing correspondingly rapid sedimentation rates. Colloidal stability can be a factor in eutrophication.

High calcium concentrations promoted coagulation in Onondaga Lake.
“The high Ca 2+ concentrations promoted coagulation (Weilenmann et al. 1989)”
From Assessment of Long-term Trends in the Oxygen Resources of a Recovering Urban Lake, Onondaga Lake, New York (2006) · cites this paper as Weilenmann et al. 1989
The Abstract says calcium ions enhance natural coagulation, and the Experimental methodology says low DOC and high calcium favor coagulation. But the study focuses on Swiss lakes, chiefly Zurich and Sempach; our copy does not establish that high calcium promoted coagulation in Onondaga Lake. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
