Research on the International Geodynamic Test-Area Plitvice Lakes within CERGOP-2 Project

Activities on this work-package subgroup include preparation activities at the University of Zagreb, Faculty of Geodesy and field reconnaissance in the area of the Plitvice Lakes National Park. The combination of equipment has been tested in the field and it is now ready to be deployed in the Plitvice Lakes test area. The goal is to measure the Lake Kozjak with the combination of precise bathymetry and RTK GPS (Real Time Kinematics). In the area of Plitvice Lakes, we were looking for the best positions (sky clearance, obstacles, satellite visibility, ground stabilization) for future geodynamic GPS-measurements. At the same time, we have chosen the points which will be used as base points for hydrographic measurements using the RTK-method. The cooperation with the Croatian Hydrometeorological Institute was established in order to compare the datasets of previous hydrological measurements with current situation in the Lakes. In cooperation with the tectonic experts we prepare the structural map of the area of the Plitvice Lakes in order to find better explanation for possible movements of tectonic units in the area. The geological situation is particularly important for hydrologic assessment since the loss of water (lowering of water level) in the lakes is caused by faults.
