dc.description.abstract | Phytoplankton is one of the crucial components of water body ecosystems. Its presence and development depend
on biological, physical and chemical factors and in consequence it is an important indicator of ecosystem condition.
Monitoring of phytoplankton production, measured as chlorophyll a concentration, is a useful tool for
assessing the status of dam reservoirs. Modeled chlorophyll a concentrations are used as water quality indicators
in locations not included in monitoring systems, in situations when the temporal resolution of the monitoring is
not enough, and in assessments of the impacts of future activities. Therefore, the aim of this study was to find
correlations between hydro- and thermodynamics and the chlorophyll a concentration for possible application in
reservoir monitoring and management, using an ELCOM-CAEDYM model. The analysis included summer and fall
which are most prone to algal blooms, and four phytoplankton groups identified as dominant in the reservoir
based on periodic observations.
Comparisons of simulated water temperature and both observed and simulated chlorophyll a concentrations
confirmed that these variables are significantly correlated (correlation of hourly chlorophyll a and water temperature
was 0.70, ranging from 0.55 to 0.81 in the bottom and surface water layers, respectively, while for daily
outputs it was 0.74, ranging from 0.60 to 0.83). This relation was stronger than that of chlorophyll a to nutrient
(N, P and Si) concentrations. What is more, the method used allowed the assessment of a much more detailed
spatial and temporal distribution of phytoplankton groups compared with conventional monitoring techniques.
The study indicated that the phytoplankton community was dominated by Chlorophytes and Diatoms with a
larger share of Chlorophytes in shallow parts of the reservoir. This domination was weaker after short water
mixing events in summer and especially after the fall turnover. The increase in phytoplankton diversity was
estimated to occur mainly near the surface and in shallow parts of the reservoir. Most of the observed concentrations
of individual phytoplankton groups differed from simulation results by less than 25% and the model
reflected accurately 74% of observed trends in concentrations. Calculated chlorophyll a concentration was well
matched to hourly monitoring data (mean squared error = 5.6, Nash–Sutcliffe model efficiency coefficient =
0.51, Pearson correlation coefficient = 0.72 and p-value = 0.0007).
High compatibility of the model to the values measured in the reservoir make it a promising tool for the
prediction and planning of actions aimed at maintaining good functioning of the reservoir. | pl_PL |
