- 2.1. Geographic characterisation in the Tisza River Basin

The Tisza River Basin is the largest sub-basin of the Danube River. The drainage basins of the tributaries of the Tisza River differ from each other in topography, soil composition, land use and hydrological characteristics. The 1800-2500 m high ridge of the Carpathian Mountains create in a semicircle the northern, eastern and southeastern boundary of the Tisza catchment. The western – southwestern reach of the watershed is comparatively low in some places – on its Hungarian and Serbian parts it is almost flat. The area is divided roughly along the centreline by the Carpathians Mountains, east of which lies the 400-600 m high plateau of the Transylvanian Basin, and the plains to the west. More information and maps on the geographical features of the Tisza are given in this section. (3.1. Geographic characterisation - p.17)
