Effects of water level variations on the dynamics of the reed belts of Lake Constance

Following the extreme flood at Lake Constance in 1999 the reed belts of the shore of Baden-Württemberg lost approximately 30 ha (24%) of their lakeside reed beds. This loss is comparable with the situation in the late 1960s, when approximately 40 ha died back due to the extreme flood in 1965 and due to the high spring water levels in the subsequent years. In the time period between the extreme ...

Effects of the invasive Asian clam Corbicula fluminea on the littoral communities of Lake Constance

The Asian clam Corbicula fluminea, originating from Southeast Asia, was first recorded in Lake Constance in 2003 and developed local mass occurrences afterwards. Effects of harsh winter conditions in 2005/2006 associated with a strongly decreasing water level were studied at 3 different depths at and below the mean low water level (MLL, MLL -1 m and MLL -3 m). Low winter temperatures produced a...

Seasonal variation of solitary wave properties in Lake Constance

[1] The properties of internal solitary waves (ISWs) depend on the stratification of the water body. In most climatic regions the stratification in lakes and oceans varies during the year, and hence the properties of the ISWs can also be expected to change over the seasons. On the basis of a long-term temperature time series recorded over 6 years, this paper investigates seasonal changes in the...
