The paper provides basic data on recently established monitoring sites and results of pore pressure measurements in the body of Radovesice dump. In the area of Radovesice dump, an extensive monitoring network was established at the site which was affected by landslides in 1994. At first, 14 hydrogeological boreholes were established. Casing of the boreholes was placed up to different aquifers of the dump and its underlying bed. The level of groundwater is monitored in these boreholes on a long-term scale. At present, groundwater level is measured only in 8 boreholes. During the years 2009 and 2010, the monitoring network was extended by 3 new boreholes, where pore pressure sensors were installed. The sensors were placed in the aquifers of the dump and its bed. The results of pore pressure measurements and groundwater level monitoring help to indicate the states of potential alerts.
