General Characteristics

The city lies within the Pannonian Basin, a vast lowland region that stretches across Hungary, Austria, and parts of Serbia and Bosnia and Herzegovina. The terrain surrounding Osijek is gently rolling, with elevations typically ranging from 80 to 100 meters above sea level. The Drava River, which flows through the city, has played a significant role in shaping the local topography, creating floodplains and terraces along its banks.

These areas are prone to flooding during spring and summer, when the Drava experiences its highest water levels. The river’s terraces, located slightly higher than the floodplain, provide a more stable and flood-free environment for settlements. The city of Osijek is primarily situated on these river terraces, which offer a panoramic view of the surrounding Drava Valley.
