Lateral migration of the Jiu river course between 1864 and 2018. Case study: Craiova – Zăval sector

Abstract: During the last 154 years, the Jiu river course that stretches from its confluence with the Amaradia down to the outlet has undergone serious lateral and length changes. The main purpose of this article is to highlight these changes, to determine their magnitude, and to understand the future evolution of the Jiu course.
The results of our analysis showed that from 1864 until 2018, the Jiu river became shorter in the lower section, decreasing with 38.1 km, from 134 km to 95.9 km. The shorten-ing of the course happened gradually. Thus, between 1864 and 1910, the length of the course decreased by 25.6 km, from 134 km to 108.4 km. From 1910 until 1970 there was a shortening of 11.9 km and between 1970 and 2018, the river shortened its course by about 0.6 km. The greatest lateral distance between its historical and present channels showed a maximum of 11.22 km on the outlet.
