Implementation of a strategic development of coastal zone management.


Project objectives

The GRoW-joint project go-CAM, funded by the BMBF (Federal Ministry for Education and Research), deals with the implementation of a strategic development of coastal zone management.

Short description

The main objective of go-CAM is the development, implementation and application of multicriteria optimisation for a sustainable usage of groundwater in coastal regions. By combining modern methods that support decisions and actions with hydrogeological modelling, the project team seeks to generate a general and integrational coastal management system. Once completed, this tool is part of the online platform “Coastal Aquifer Management (CAM)”. Furthermore, by applying the developed software and optimisation procedure on test sites in Brazil, Turkey and South Africa, the coastal management system is internationally established. The basis to appraise the useable groundwater and the corresponding demand in coastal regions are up-to-date hydrologic, hydrogeologic and geologic models. The tool to derive options for different actions in a specific region will be the multicriteria decision analysis implemented in the CAM. Accompanying workshops for potential users will increase the acceptability of the developed procedure. An international PhD program involving the project partners ensures the applicability of the developed system even after the scheduled project runtime.

This joint project is initiated by Prof. Dr. H.M. Schöniger, TU Braunschweig.

The main objective of the subproject at LIAG is to increasing the accuracy and thus the reliability of the obtained input parameters for hydrologic groundwater models and to monitor dynamic processes of the freshwater/saltwater transition zone with geophysical methods.

January 2019: LIAG installs salt water monitoring system SAMOS at Jever

Sustainable use of water resources is a particular challenge in coastal regions worldwide. Salinization can endanger the groundwater and thus the drinking water supply. In order to investigate the fresh-salt water transition zone in the subsurface in the long term, LIAG employees recently installed a vertical electrode chain near the Ems-Jade Canal at a depth of around 30-50 m. With this measuring system, physical parameters are recorded daily. As part of the go-CAM project, the data is entered into an information and dialogue platform and contributes to a sustainable water supply. The measurements at Jever are the prelude to worldwide use of the system. The work is part of the BMBF funding measure GRoW, which aims to increase control competence in the water sector and thus contributes to achieving SDG 6 of the United Nations.

March 2020: LIAG installs saltwater monitoring system SAMOS on Spiekeroog

Scientists from the Leibniz Institute for Applied Geophysics (LIAG) have installed for the first time a salt water monitoring system (SAMOS) on the island of Spiekeroog in cooperation with the Oldenburg-East Frisian Water Association (OOWV). With the help of the geoelectric measuring device, changes in the salt-fresh water limit in the protective dunes area of the island are monitored. The real-time evaluations provide crucial information for sustainable water management by the OOWV.
