Analysis of Drought Events - Case Study for Blanice River Catchment (Czech Republic)

Popis výsledku v původním jazyce

Expected results of considered climate changes consist mainly in the more frequent flood events having higher magnitudes as well as in more frequent periods of droughts with longer duration in conditions of Czech Republic as well as in neighbouring countries. This can result in losses caused by both floods and droughts. The procedures for flood frequency analysis are clear and well established while droughts cannot be defined and analysed without consideration of conditions in given regions. It is therefore necessary to analyse time series in order to define both meteorological and hydrological droughts as well as their coincidence in statistical manner. The purpose of this analysis consists besides others in the correct planning of drought mitigation policies. As a case study area, the catchment of Blanice River has been chosen. This catchment has an area of 534 km2 and is located about 40 km southeast of Prague. For the analysis, the data from three discharge gauging stations and three meteorological stations were used. The daily time series of discharges, precipitations and temperatures used for the analysis were all 50 years long. The analyses needed to be carried out with the consideration of different durations of drought periods in order to define drought before it could be analysed from the point of view of trends. In general, trends were identified in analysed data with respect to annual values which can be understood to be in agreement with considered climate changes. However, no significant trend was identified in drought with respect to their total annual duration.
