Invitation to join webinar on tackling eutrophication in lakes

lake balaton in hungaryThe Lake Balaton Development Coordination Agency has invited Living Lakes partners and friends to join a free online seminar on ‘Experiences and good practices to tackle eutrophication in shallow lakes applying thin-layer sediment dredging technologies’ which takes place on March 16 2021.

With about 600 km2 surface area, Lake Balaton is the largest freshwater lake in Central Europe and it is one of the most important natural treasures of Hungary. Just like in case of other shallow lakes, sediments play an important role in the nutrient cycling of Lake Balaton.

As a result of high external loads of nutrients in the past, sediments became storages of such substances. The surface layer of sediments of shallow lakes can readily be resuspended due to wind induced wave action and contribute to the nutrient load (internal load) and, eventually to eutrophication which is manifested in harmful algal blooms.

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 seminar, we would like to draw attention to the importance and impacts of sediment dredging on large shallow lakes, and to introduce Hungarian and international dredging best practices and experiences. The planned programme of the event can be found in the attachment. The language of the event will be Hungarian, English and Japan, with simultaneous interpretation.

The seminar will be organized on ZOOM,  the direct link, meeting ID, and passcode to join the meeting are found below: https://us02web.zoom.us/j/88647427533?pwd=YXdtNlFvUy8wN2hHeWdwSmk2enFSQT09
