Abstract

It is of fundamental importance in lake mass balance modelling to distinguish between the dissolved and particulate fractions. To do this, the suspended particulate matter concentration (SPM) is needed as well as measured ormodelled values of the partition coefficient (K-d). A regression model forSPM based on data from 26 European fakes covering a wide limnological range is presented. The model yields an r(2)-value of 0.87. It predicts lake typical SPM values from lake total phosphorous concentration (TP), reflectingthe influence of bioproduction on SPM, pH, reflecting allochthonous and autochthonous influences on SPM and the dynamic ratio (DR), a morphometric parameter reflecting the influence of resuspension on SPM. The model is shownto be stable, easy to use, and since the model parameters have a wide range, the model can be very useful in predictive lake modelling. (C) 1999 Elsevier Science B.V.
