In the section above Tiszaújlak, despite the presence of embankments, the River Tisza shows active meandering tendency and it splits into branches resulting in side channels, dead channels and backwaters that follow the main channel. In our work we examined the right- and the left-side riverbank sections of the River Tisza, between Tiszaújlak (Вилок) and Tiszasásvár (Тросник), as well as between Tiszaújlak and Tiszapéterfalva (Пийтерфолво), to reveal the extent of bar depositions between 2006 and 2015, and to what extent the intensity and direction of the riverbank formation processes were influenced by the material of the bank and the plant coverage, its rate and characteristics. We tried to reveal which sections were eroded by the river and what security risks they have for the safety of the settlements along the Tisza River. On the right side of the Tisza River riverbank 51, and on the left side 62 main measuring points were recorded by GPS positioning satellite in 2009, 2010 and 2015. Our results were compared to the satellite images of Google Earth taken in 2006, too. According to our experience, in several bends of the examined sections of the river, active bar deposition can be observed; in some cases more than 100 m of bar depositions were detected.

According to the last Ukrainian census in 2001, 152 thousand people declared Hungarianethnicity in Transcarpathia. Since that time, there is no reliable and up-to-date data on theethno-demographic development of the region's population. It is especially hard to register themigration flows particularly salient since the outbreak of the armed conflict in East Ukrainein 2014. Based on four data sources (official Ukrainian and Hungarian statistics and tworepresentative surveys), the present study aims at revealing the volume of the permanent andtemporary migration of Hungarians in Transcarpathia and its impact on their number. Wefound that the same migration flow is associated with various figures by each of the data sourcesconducted with different methods and by different actors. According to the more reliable surveys,9 to 14 thousand ethnic Hungarians emigrated from Transcarpathia since 2001; consequently,the number of Hungarians is estimated at approximately 130 thousand people in the beginningof 2017.
