Since the Unified Silla Period, when Jeonju began to appear in history, the impact of flow change of Jeonju Stream and change of central region, it was reviewed focusing on the existing discussions. The results of the study is, first, the rivers flowing through the Jeonju area can be divided into internal rivers (Nosong Stream, Inbong Stream, Morae Stream, Ajung Stream) and external rivers (Jeonju Stream, Sam Stream). Among them, Jeonju Stream is the river that played the most important role in the formation of the flatland in the old downtown areas of Jeonju. Second, the possibility of moving to the west of Jeonju Stream recorded in ‘Jeonju Busa (1943)’ is valid, but it is unreasonable to directly relate it to the time of construction of Gyeonhwon Castle (900 years). Third, in the old downtown area of Jeonju, schistise granite forms bedrock, and a sand layer of about 1m and a clay layer of about 1.8m are formed on it by the sedimentation of Jeonju Stream. In addition, in the eastern hilly area (Nosong-dong), the weathered soil moved to the west (the direction of Jeonju Stream), and 1.5m was deposited on it. Fourth, Jeonju Stream was already stabilized around 900 years, the time of the construction of Gyeonhwon Castle, and it was Nosong Stream, a tributary, that influenced the construction of Castle. Fifth, various estimates have been made on the purpose of the shape of a Line Fortress built in the direction of Jeonju Stream from Old Fortress, which may have been defense facility to protect the old city area from flooding from the north or the influence of Feng shui. Sixth, Jeonju Stream, which was flooded, was controlled by artificial embankment construction and direct reinforcement work from the 1940s to 2000, and played an important role in the direction of regional development in Jeonju City.
