Hydrodynamical effects on spatial distribution of enteric bacteria in the Jordan River - Lake Kinneret contact zone

The aim of this study was to determine under what hydrodynamic conditions t he change in the number of enteric bacteria in the water of the River Jorda n-Lake Kinneret contact zone was due to sedimentation and under what condit ions the change was due to dilution. The data were then utilized to build a conceptual model explaining the distribution of biological pollutants (bac teria) in the river-lake contact zone of a shallow tropical lake. The study uses, as an example, the microbial communities of the River Jordan-Lake Ki nneret contact zone. The changes in numbers of three groups of bacteria (fe cal coliforms, Escherichia coli and Klebsiella pneumoniae) along the jet fl ow agree well with changes in the concentration of suspended particulate ma tter, caused by the sedimentation of particles, (C) 2000 Elsevier Science L td.
