Abstract


FROM FLOOD TO DROUGHT – CHANGES OF HYDROGEOLOGICAL SITUATION IN POLAND BETWEEN 2010–2015

Abstract. Hydrogeological and hydrological situation is primarily conditioned by climate and natural features, however, land use and catchment management are also important. Both droughts and low groundwater levels, as well as floods and flooding have been occurring in Poland in the past and they will certainly be repeated in the future. Undertaking measures aimed at effective mitigation of effects of such extreme events is possible. Nevertheless, this requires reliable and verifiable hydrogeological forecasting. In order to meet these expectations, the Polish Hydrogeological Survey undertakes cyclic assessments of hydrogeological situation in Poland on a national scale and carries out projections of its changes. This paper presents results of an analysis of hydrogeological situation in Poland between 2010–2015, during which a transition from high groundwater levels in 2010 and 2011 (related to flood events in 2010) to low levels (related to the drought in 2015) were observed. To present the spatio-temporal changes of hydrogeological situation in years 2010–2015 the authors analyze extreme groundwater levels in the considered period based on data from the national groundwater monitoring network of the Polish Geological Institute – National Research Institute.
