The University of Thessaly - School of Engineering, Department of Civil Engineering - organises online scientific lectures series.
The title of the online lecture by Mr Nikolaos Mellios (Live Streaming: ch 3 - live.uth.gr) University of Thessaly on 18/11/2020 was “Environmental informatics for modelling of freshwater ecosystems: dynamics and impacts of eutrophication and sustainable agricultural water use”. The potential of ecological modelling under the frame of environmental informatics to define the factors that affect water quality and quantity parameters on lake ecosystems were presented. Karla Reservoir, a Greek hypertrophic constructed lake, suffers from continuous water degradation because of excessive nutrients loading, unaccomplished works, and operational malfunctions. Ecological modelling is conducted to simulate in-lake nutrient dynamics and to reveal the factors affecting its trophic state, while several operational scenarios and a climatic one is applied to estimate the fate of the lake under these hypothetical circumstances. Also cyanobacteria biomass and recreational health risk levels associated to cyanobacterial abundance are modelled on a network of Northern European lakes. Lastly, an analysis in terms of which types of crops export the most virtual water through trade, in relation to the benefit in Greek economy, is conducted.
