Abstract

Due to the weather extremes the water level of the Danube has become more fluctuating. With constant measurement, the effect of the flood of the Danube on the mass field is calculable. Having made enough observations, the time variation of gravity gradients due to the fluctuation of the water level may be predictable. The mass model of the Danube, created to simulate the gravitational effects of the fluctuations, was composed either by polyhedron volume elements or homogeneous density polyeders. After the simulations, the gravity gradients of the different mass models were compared to the previous measurements made by Eötvös torsion balance.
