text: Szabolcs-Szatmár-Bereg is Hungary's sixth-biggest county with a total land area of . From a geographical aspect, it is possible to divide the county into two main regions: The Upper Tisza Valley and the Nyírség. Tisza is one of the most important rivers of the county, entering Szabolcs-Szatmár-Bereg — and Hungary — at Tiszabecs, and leaving at Tiszadob. Its segment in Szabolcs-Szatmár-Bereg county is 235 kilometres long, out of which  belongs to the Upper Tisza Valley, reaching the area of Tokaj and Rakamaz. The larger area named the Nyírség is derived from the word nyír meaning birch, as the region is dominated by birch woodlands. The northern part of Nyírség is covered with sandy forest soils, the southern areas have loose wind-blown sand. Alluvial and meadow soils are found in the Upper Tisza region.
  The county has a continental climate; it is cooler than the Great Plain because it is further north. Summers are cooler than in other parts of the Plains. Annual precipitation is 550–600 millimetres. The higher than average number of days of sunshine make ideal conditions for the growing of tomatoes, sunflower, tobacco, apples, and other fruits such as plums—for which the county is famous, being eaten fresh, dried into prunes (some made into lekvar) and fermented into well-known brandies.
  The county has 229 settlements, of which 20 are towns. The county capital and largest city is Nyíregyháza with a population of 116,900 in 2003. The other cities have relatively small populations, only those of Kisvárda and Mátészalka having around 18,000 inhabitants. The eastern part of the county is lightly populated and is dotted with small villages which often have very poor economic conditions.
  The Tisza River
  The Upper Tisza region has many streams and rivers, but the Nyírség region has little surface water. The most important of Tisza's tributaries is the river Szamos, which is also characterised by great variations in water volume. There are irrigation systems, a water barrage, and a hydroelectric power station on the Tisza at Tiszalök.
