Abstract: Lateral adjustments of Timiș river channel between 1965-2015.
Until now, most of the studies regarding Timiș river are hydrological and
engineering a pproaches for the fl ood risk or chemical water composition. This
paper wants to be a geomorphological approach of the Timiș river channel, for a
50 years temporal evolution period. The aim of this paper is to assess and
analyze the major planform channel adjustments of Timiș river between Buchin and
Lugojel. The sector is located in a transition area, on the middle course, from
the Timiș-Cerna Corridor, to Sinersigului and Lugojului Plain. The study area
contain the most meandering sector of all the Timiș river course, both from
Romania and the Republic of Serbia. The methodology we used for this present
paper is composed of G.I.S techniques and also, fi eldwork. Furthermore, we used
two specifi c aspects for the lateral channel adjustments analysis: the
meandering average rate and the lateral morphometric values on a cross section.
By the integrated analysis of these two aspects, we could identify and interpret
the main lateral channel adjustments of Timiș river. The fi nal results helped
us to asses the late 50 years planform morphodynamics of the river. Also, the
G.I.S. techniques combined with the mathematical modelling proved to be a very
effi cient tools in river planform adjustments assessment.
