Climate change impact on recurrence and regime of runoff extremes: floods and droughts

An example of the Middle Daugava RiverDvis GRUBERTS, Dr.biol.Daugavpils University Pardes str. 1, Daugavpils, LV-5401e-mail: [email protected]

IntroductionAim of the study:to evaluate long-term changes in the reoccurence (probability) and regime of the runoff extremes (floods and droughts) of the Middle Daugava River in context of climate change.

Data sourcesThe Global Runoff Data Centre, Koblenz, Germany (www.grdc.bafg.de) daily mean discharges of the Daugava River at Daugavpils (GRDC No. 6973300, 1936-2007);The National Climatic Data Centre, Asheville, NC, USA (ftp://ftp.ncdc.noaa.gov/pub/data/gsod): daily mean air temperature, amount of precipitation and thickness of snow cover at Riga, Daugavpils and Vitebsk weather stations (1964-2006).

Statistical analysis of the hydrological drought reoccurence (probability distributions)selected periods: 1936-1977, 1966-2007 (summer and all-year droughts); 1936-1987, 1956-2007 (winter droughts);threshold level for the distinction of the hydrological drought periods: 70 %;parameters: all-year droughts; summer droughts (June 5 November 9); winter droughts (November 10 June 4);estimated probability distributions: relative runoff deficit; real low-flow duration; full low-flow duration;the program: Nizowka 2003 (Distributions of Low Flow Extremes)*.

Climate change impact

Climate change impactExample 2: Correlation between the mean monthly discharge of the Daugava River and the mean air temperature at Daugavpils in March

Main conclusionsIn general, the climate of the Daugava River drainage basin becomes more warm and wet, with less snow in winter.The climate becomes also more diverse on the regional scale.The annual discharge of the Middle Daugava correlates better to the climatic characteristics of the Vitebsk weather station. Peculiaries of the climate change and the Daugavas runoff regime are better seen on the monthly scale.The probability of reoccurence and the magnitude of typical runoff extremes of the Daugava River are decreasing.The possibility to predict the date of the annual floods peak is also decreasing.Predictions of the future c
