ESTIMATION OF THE CORIOLIS-FORCE SIZE FOR TISZA RIVER

Full text

We tried to estimate the size of Coriolis force for Tisza River, which we consider responsible for the westward shifting of the river. We do not deny the tectonic footprints of the river courses, which have mostly locally, well encountered effect, but due to the regional course change we consider that Coriolis force can reach sizes, which long lasting effect change the course of the rivers especially in low land regions, like Great Hungarian Plane. Our estimations refer to the different segment of the Tisza River. In the Great Hungarian Plane where the capacity of work of a river is close to minimum, this can increase in case ofrainy periods where foods used to appear. These estimations proves that in such rainy and flood periods, dueto the increased density and flow speed, the Coriolis force riches a size, which force work and powerdepends on the flowing speed following square low. This power is responsible for the bank erosions.
