Radar Hydrography

To acquire the structure of the sea bed, the shiftings of sands and other sediments in the water, are commonly time and costs intensive navigations necessary. The employees of the departement for radar hydrography are developing radar supported measure methods, with which it is possible to analyze the shape of the sea bed with less complexity from the shore. The structure of the sea bed affects the dispersion of the sea condition. The coastal scientists of Helmholtz-Zentrum Geesthacht are using these legalities and developing programs, which are able to assess the soil structure under water ( Bathymetrie ) out of the movement of the specimen of the sea condition. For the measurement of the specimen of the sea condition the scientists employ radar technology. Such inquiries are for instance relevant for coast protection and navigation. So it is contingent to check from the coast per radar where sand is rinsed by storms or how strongly a fairway is adjusting at the mud flat area.

At present the scientists are working on a new radar method for measuring water currents - also for the investigation of sediment transports. A further project is the acquisition of huge arduous waves on the main sea, so called breakers. This information is of note for the constructors of offshore - wind properties, because so far it isn´t explored, how the breakers affect on wind properties and if the constructions even create breakers by themselves.
