Humic substances as fluorescent indicator of hydrological structures in inland reservoirs

The results of the field studies of the humic substances as the natural indicators of the hydrological structures conducted on the Rybinskoe reservoir in 2003-2008 were generalized. The diagnostic features of the two characteristics of the humic substances fluorescence – intensity and the class of the fluorescence band evaluated using the classification algorithm of the artificial neural networks – were studied. The results of the classification were compared to the variations of the photophysical parameters of the humic substances of different genesis obtained using the technique of laser fluorimetry.
