Living Lakes Partners invited to seminar on sediment use

The Lake Balaton Development Coordination Agency is organizing an online event on May 6 2021 entitled ‘What shall we do with the dredged sediment? International experiences and good practices for the disposal and utilisation of sludge at large shallow lakes’.

In shallow lakes, sediments play an extremely important role in the nutrient cycling. As a result of high external loads of nutrients in the past, sediments became storages of such substances. Removal of the most active, most polluted surface sediment layer (10-30 cm) by thin layer dredging is a common technique in water quality/eutrophication control. In addition to overall water quality improvement of a shallow lake, dredging may contribute to providing better quality and utility value for beaches and small-boat harbours.

In the previous seminar, we reviewed the scientific background of sediment dredging in shallow lakes, and the experiences at Lake Balaton and good dredging practices from abroad. This time, we would like to focus on the disposal and utilisation of removed sediment. In the seminar, firstly we will briefly introduce the current situation at Lake Balaton and, as an international outlook, the current situation at Laguna de Bay in the Philippines.

Then we will review the concerns and questions about the disposal of sediment, and introduce some alternative solutions and technologies available for the utilisation of sediment based on international experiences. In addition, we would also like to analyse whether dredging can provide a permanent solution for keeping good water quality in long-term.

The language of the event will be Hungarian and English, with simultaneous interpretation.

The seminar will be organized on ZOOM platform. The direct link, meeting ID, and passcode, which are required to join the online event, can be found below:
