2015 ANNUAL MEETING INTERNAL EROSION IN EMBANKMENT DAMS, LEVEES AND DIKES, AND THEIR FOUNDATIONS 29th Sept to 2nd Oct 2015 – Wierchomla, Poland

With the support of the Polish Committee on Large Dams (POCOLD), the Polish Institute of Meteorology and Water Management (IMGW) organized the XVI International Technical Conference on Dam Monitoring, in Wierchomla from the 29th September to the 2nd October 2015.

The XVI International Technical Conference on Dam Monitoring hosted the 2015 Annual Meeting of the ICOLD European Working Group on Internal Erosion in embankment dams, levees and dikes, and their foundations (EWGIE). This Conference included a session called Internal Erosion in Earth Structures.

During the conference, Prof. Pawel Popielski (Warsaw University of Technology) and Dr Krzysztof Radzicki (Cracow University of Technology) were the organizers of the EWGIE 2015 meeting.
