| Zusammenfassung |
| The June 2013 flood in the Upper Danube Basin was one of the largest floods
in the past two centuries. An atmospheric blocking situation produced
precipitation exceeding 300 mm over four days at the northern rim of the
Alps. The high precipitation, along with high antecedent soil moisture, gave
rise to extreme flood discharges in a number of tributaries including the
Tiroler Ache, Saalach, Salzach and Inn. Runoff coefficients ranged from 0.2
in the Bavarian lowlands to 0.6 in the Alpine areas in Austria. Snowfall at
high altitudes (above about 1600 m a.s.l.) reduced the runoff volume
produced. Precipitation was distributed over two blocks separated by a few
hours, which resulted in a single peak, long-duration flood wave at the Inn
and Danube. At the confluence of the Bavarian Danube and the Inn, the small
time lag between the two flood waves exacerbated the downstream flood at the
Danube. Because of the long duration and less inundation, there was less
flood peak attenuation along the Austrian Danube reach than for the August
2002 flood. Maximum flood discharges of the Danube at Vienna were about
11 000 m3 s−1, as compared to 10 300, 9600 and
10 500 m3 s−1 in 2002, 1954 and 1899, respectively. This paper
reviews the meteorological and hydrological characteristics of the event as
compared to the 2002, 1954 and 1899 floods, and discusses the implications
for hydrological research and flood risk management. |
