| Numerical modeling and research intrest | ||
A computer simulation, a computer model or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics (computational physics), chemistry and biology, human systems in economics, psychology, and social science and in the process of engineering new technology, to gain insight into the operation of those systems, or to observe their behavior. In earth science, numerical and analogue modeling is generally used to understand processes which take place at timescale larger than the human lifespan. Numerical modeling is also used to understand the impact of different processes for example precipitation on the evolution of a mountain range. In 2008 and the beginning of 2009 I was working on the possibility of a salinity crisis in the Paratethys. The Paratethys ocean, Paratethys sea or just Paratethys was a large shallow sea that stretched from the region north of the Alps over Central Europe to the Aral sea in western Asia. The sea was formed during the Oligocene epoch (after 34 million years ago) when it was separated from the Tethys Ocean to the south by the formation of the Alps, Carpathians, Dinarides, Taurus and Elburz mountains. During its long existence the Paratethys was at times reconnected with the Tethys or its successors, the Mediterranean Sea or Indian Ocean. From the Pliocene epoch onward (after 5 million years ago) the Paratethys became shallower, today’s Black Sea, Caspian Sea and Aral Sea are leftovers of it.
The Paratethys is located north of the mediterranean Sea and encompasses the Pannonian basin, Black Sea, Caspian Sea and Aral Sea.(http://www.geol.umd.edu/~tholtz/G102/102ceno2.htm) The research was concentrated on the possibility of a salinity crisis (i.e. a significant sea level drop of more than 1000 meter) in the Paratethys. It started with the modeling of the connectivity between the Dacic and Black Sea basin using Toa3d at the VU University Amsterdam together with Matenco L. Leever K. Garcia-Castellanos D (paper in progess). After this, Rob Govers and I used gflex, to constrain the magnitude of this sealevel drop (paper submitted). At this moment we are starting to work on the uplift of the Anatolian plateau. Stretching inland from the Aegean coastal plain, Central Anatolia plateau occupies the area between the two zones of the folded mountains, extending east to the point where the two ranges converge. The plateau-like, semiarid highlands of Anatolia are considered the heartland of the Turkey. The region varies in elevation from 600 to 1,200 meters (2,000 to 4,000 ft) from west to east. The two largest basins on the plateau are the Konya Ovası and the basin occupied by the large salt lake, Tuz Gölü. Both basins are characterized by inland drainage. For this new project, as part of the VAMP project, we are going to study the birth and development of orogenic plateaus with an emphasize on the Anatolia plateau. . Source: Wikipedia |

Example of a numerical model to calculate stresses and displacements in this case along a fault
Tao3d is a numerical model to simulate the interaction between processes deep in the earth and processes at the surface of the earth. (http://cuba.ija.csic.es/~danielgc/tisc/) |
