The aim of this article is to describe an innovation in the monitoring of performance of earth embankments, namely the use of sensing systems for full-time monitoring of dam and levee seepages. The monitoring system being developed by the companies VODNI ZDROJE (czech Republic) and EGIS (Republic of Korea) within the EUREKA project Short Term Assessment and Mitigation of Flood Risks is based on the measurement of temperature changes in the embankment body by using the discrete and distributed temperature sensors. The article provides an overview of the activities performed at the reservoir earth dam in pilot site Vlckovice v Podkrkonoší and describes the (i) preliminary activities necessary for the proper spatial distribution of sensors in the embankment body including the geophysical and geotechnical survey and (ii) collection and evaluation of the data.
