Hydrography in water management
Abstract
This paper describes the surveying of the delta plain of the River Rhine at Lake Constance using multi-frequency as well as multi-beam sounding systems. The total area of about 100 km2 was surveyed at the beginning of 2008. The Rhine originates high in the Swiss Alps and enters Lake Constance on Austrian territory. The resulting subaqueous delta is constantly growing due to the enormous load of suspended sediments resulting from erosion processes along its course of more than 100 kilometres. Since 1911, hydrographical surveying is undertaken every ten years to determine the distribution and thickness of sediments in the Lake Constance basin. Within the last 50 years, dams had to be built to displace the mouth of the river by about five kilometres from the original lakeshore to deeper zones of the lake. It was possible to calculate the change in the distribution and amount of sediments based on data from previous bathymetric campaigns calibrated using sediment probes from different places within the project area. Data from a network of gauging stations at major tributaries were used to verify the sediment displacements determined at the delta.
