| Abstract [eng] |
The extreme hydrological phenomena of rivers (spring floods and flash floods of summer and autumn seasons) were carried out according to the geographical and climatic conditions of Lithuania. The statistical methods were applied for analysis of the flood patterns changes in the past and hydrological modelling were used for floods projections in 21st century. EU Water Framework Directive (2000/60/EC) laying down the framework for Community action in the field of water policy and directive on the assessment and management of flood risks (2007/60/EC) require that country policy makers and decision-makers take into account the changes in water resources in relation to climate change when assessing the risks of future floods and invite them to regularly update their projections using the newest generation climate scenarios. In this work, the created methodology of floods projection (adjusted in Lithuanian conditions) based on RCP climate scenarios allowed to assess the potential impact of climate change on spring floods and flash floods of summer-autumn season in near (2016-2035) and far (2081-2100) future. After the evaluation of uncertainties of projections, the recommendations and proposals for the preparation of documents for the protection and management of resources of water bodies were created. Also mentioned methodology for projections of spring floods and flash floods of summer-autumn season can be applied for the river catchments from the South-Eastern Baltic Sea region with similar physico-geographical and climatic features, like in selected river catchments of this thesis. |
