Setting the Phosphorus Boundaries for Greek Natural Shallow and Deep Lakes for Water Framework Directive Compliance

Kagalou I, C. Ntislidou, D. Latinopoulos, D. Kemitzoglou, V. Tsiaoussi, and DC Bobori. 2021. Setting the Phosphorus Boundaries for Greek Natural Shallow and Deep Lakes for Water Framework Directive Compliance. Water 13(5):739. https://doi.org/10.3390/w13050739Eutrophication caused by nutrient enrichment is a predominant stressor leading to lake degradation and, thus, the set-up of boundaries that support good ecological status, the Water Framework Directive’s main target, is a necessity. Greece is one of the Member States that have recorded delays in complying with the coherent management goals of European legislation. A wide range of different statistical approaches has been proposed in the Best Practice Guide for determining appropriate nutrient thresholds. To determine the nutrient thresholds supporting the good status of natural Greek lakes, the phytoplankton dataset gathered from the national monitoring programme (2015–2020) was used for shallow and deep natural lakes. The regression analyses were sufficient and robust in order to derive total phosphorus thresholds that ranged from 20 to 41 μg/L in shallow and 15–32 μg/L in deep natural lake types. Nutrient boundaries that encompass the stressors these lakes are subject to, are essential in proper lake management design

Assessing lake vulnerability to climate change using the coupled MIKE SHE/MIKE 11 model: Case study of Lake Zazari in Greece. Paper presented at 11th World Congress on Water Resources and Environment (EWRA 2019) “Managing Water Resources for a Sustainable Future”. Madrid, Spain, 25-29 June 2019

If the worst predictions of general circulation models (GCMs) about climate change become true, then lakes will hardly manage to maintain their current conditions (Zhang et al. 2016) especially in regions, which have been identified as climate change hot spots such as the countries of Mediterranean Basin (Loizidou et al. 2016) from which Greece is of special interest since it has 54 lakes/reservoirs of 0.5 km2 minimum size. The hydrological models are important tools for assessing the water balance components of lakes and for supporting the design of water management strategies. Depending on the modelling purposes and the specific attributes of a lake, different types of models and different levels of model complexities can be selected, starting from complex models such as MIKE SHE (Abbott et al. 1986), WATLAC (Zhang 2011) or using simpler methods (Yang et al. 2018). The MIKE model is among the most integrated models and has been used in the past for similar cases (Singh et al. 2010), while in combination with the future climate projections of general circulation models (GCMs), can be used to investigate lake conditions under future climate scenarios. The aim of this study is to present an application for analyzing the vulnerability of a lake to climate change using the MIKE SHE/11 model using as a case study the Lake Zazari in Greece

A phytosociological survey of aquatic vegetation in the main freshwater lakes of Greece

Zervas D, Tsiripidis I, Bergmeier E, Tsiaoussi V (2020) A phytosociological survey of aquatic vegetation in the main freshwater lakes of Greece. Vegetation Classification and Survey 1: 53-75. https://doi.org/10.3897/VCS/2020/48377This study aims to contribute to the knowledge of European freshwater lake ecosystems with updated and new information on aquatic plant communities, by conducting national-scale phytosociological research of freshwater lake vegetation in Greece. Moreover, it investigates the relationship between aquatic plant communities and lake environmental parameters, including eutrophication levels and hydro-morphological conditions. Study area: Lakes in Greece, SE Europe
