Hodnocení znečištění stojatých povrchových vod zelenými řasami a sinicemi pomocí jejich spektrálních vlastností
LAŠTOVIČKOVÁ, Radka
This diploma thesis deals with the evaluation of pollution of stagnant waters by green algae and cyanobacteria using their spectral properties. We chose the Hracholusky and Švihov reservoirs as a model area for evaluation. In those waters, the degradation was evaluated by determining the chlorophyll- concentration and by obtaining an evaluation reflectance from both the spectroradiometer and satellite images. Based on the results, we are able to determine that a high incidence of chlorophyll- concentration occurs in both water reservoirs, which serves as an indicator of the degree of polluting the body's surface water. In general, it can be argued that the concentration of chlorophyll-a increases in places where no water circulation occurs. In those tanks it is the beginning of the swell and also the shores. The results also demonstrate the great suitability of using Earth remote sensing data to assess the pollution of large bodies of water by algae and cyanobacteria.
