20 CONCLUSION Annual 2010/2011 of the Croatian Academy of Engineering Geodynamic study of the City of Zagreb has started in 1997 and since 2008 there has been seven GPS campaigns for the purpose of determining geodynamic movements on the points of the Geodynamic network of the City of Zagreb. Through the project Geodynamic study of the City of Zagreb, based on independent multiple precise geodetic and geological measurements, original models of tectonic movements on Zagreb area have been created. Geodetic model is based on precise GPS satellite measurements, and geological model is based on the long-term geologic measurements and studies. For this purpose data collected through GPS measurements on seven GPS measurement campaigns in the period since 1997 until 2008. Year has been used. GPS measurements were processed in the scientic GAMIT/GLOBK software, designed at MIT specically for processing GPS measurements on the geodynamic network. It calculated the geodynamic movements on the points of the Geodynamic network using modern methods of Kalman ltering. The result of the velocity models at the points Geodynamic network were obtained for the period 1997- 2001, 2001-2004, 2004-2006, 2006-2007, 2007-2008, 2006-2007-2008 and cumulatively for the whole period from 1997-2008. The maximum absolute value of displacement for the total solution in the horizontal direction is 4.3mm/yr in vertical direction 17.5mm/yr. The largest absolute values of displacements were obtained during the period 2006-2007 and are amounted to 19.4mm/yr and 50.3mm/yr in the horizontal and vertical direction respectively. It is evident that it represents signicant geodynamic movements. However, it should be noted that the mean value of velocity is 3 mm/yr. Velocity model of geodynamic movements for the whole period of the study has been created using IDW interpolation method with the inclusion of fault models of the Zagreb area. In that way the original geodetic model of the velocity eld for the wider area of the City of Zagreb. Geostatistical analysis has been performed and the correlation coefcient has been calculated for the geodetic and geological model of the geodynamic movements, by using Spearman correlation coefcient formula. The resulting value of 0.94 with signicance level of 1% (or 99% in Gaussian model) indicates a high degree of correlation between the geodetic and geological model of the geodynamic movements in the subject area. This proves the credibility of eleven year long research independently conducted by geological and geodetic methods. In conclusion, it can be stated that as part of this research a unique interdisciplinary model of crust movements over wider Zagreb area has been created for the rst time. It can be applied to precisely dene the boundaries of seismic micro-zoning of the City of Zagreb. On the other hand, results of the study can help in decision making process about reconstruction and adaptation of important structures (reinforcement of foundations and structural elements) and also they can be used to more accurately dene the zones of landslides caused by tectonic movements.
