Our understanding of the relationship between land and water has become critical in the face of natural disasters such as floods, erosion, and weather disturbances. Adam Lowe, founder of the Factum Foundation for Digital Technology in Preservation and founding member of ARCHiVe (Analysis and Recording of Cultural Heritage in Venice), and Javier Marti, founder and CEO of Divirod Inc., will discuss monitoring water and show how harmonic recordings are used to create constantly updated representations of the tide, wave activity and wind speed, helping to predict erosion and flooding.
