Abstrakt

Saltwater intrusion in coastal aquifers is of increasing concern for drinking water supply in coastal regions globally and efficient monitoring and control systems to assess and control salt water intrusion in coastal aquifers is of increasing importance.

In the Water4Coasts project we initiated work on developing and testing new monitoring sensors for measurements of chloride concentrations and efficient data upload systems to provide the necessary data for the development of a future real-time SCADA (Supervisory Control And Data Acquisition) framework for control of salt water intrusion.

The obtained data and the developed SCADA system are mainly required for controlling salt water intrusion and protecting fresh groundwater resources at coastal water wells and water works. However, it will also be well suited for sustainable management of aquifers further inland, which are affected by intrusion of saline waters from either old marine sediments or evaporation (in arid or semi-arid areas).

In this technical report we describe the outcome and main recommendations and conclusions of the conducted work towards the development of new SCADA systems for efficient control of freshwater abstraction and salt water intrusion at water works based on the monitoring of chloride concentrations in groundwater. We believe that we have developed an efficient approach for monitoring, data handling and visualisation of chloride concentrations etc., which will be key parameters for the development of future efficient SCADA systems to control salt water intrusion in aquifers. We have encountered some technical problems with the long term stability of field sensors, when they are located in surface water, and with the performance of data loggers, which have to be improved before a fully operating system is in place. However, we believe that it is possible to overcome the technical problems in the near future, and the project group will continue to develop the acquisition of data required for SCADA solutions etc. for controlling salt water intrusion in existing and future related projects.
