    Small-scale modelling is a widespread method for modelling of large-scale natural processes in the fields of hydrology, hydraulics, geology, geomorphology, river mechanics and floodplain development. Sandtables are commonly used equipment for small-scale modelling. Existing sandtables, such as the EMriver M2, are devoid of computer-controlled mechanics, and can only be tilted along their longitudinal axis. The exact tilting angle cannot be set with sufficient accuracy and, in general, quantitatively. Also, in many cases, their surface is insufficient for representing full- scale processes appropriately. The sandtable at University of Pécs is capable for the simulation of tectonic processes, such as mountain uplifting, thrust faulting, and generation of folded structures, such as anticlines and synclines. The sandtable at University of Pécs is a 4 x 2.3 meter (longest inner length and width) sandtable that is currently equipped with 4 computer- controlled electric engines. The maximum load is 2.5 metric tons of wet sand. The table can be tilted at any arbitrary angle between a maximum angle of ±7.5 degrees, and along the secondary axis at a maximum angle of ±10 degrees. The angle and rate of tilting is done by 8 fully computer-controlled electric engines. Four 50x50 cm plates in the centre of the table can be raised or lowered vertically at a rate of 10 to 200 mm per day. Maximum vertical displacement is ±120 mm. The sandtable is equipped with four lateral shovel-thruster (to vary the lateral width of the table for simulating tectonics) used for decreasing the inner with of the sandtable and to simulate orogenic processes. Maximum horizontal displacement is 200 mm. All processes are tracked by 6 digital cameras capable of generating 3D images with the aid of a computer program.
