ABSTRACT: This study aims to show the impact of successive floods on the spatial
variation of the physico-chemical properties of sediments along the Bandama
River in the localities of Sinématiali and Niakaramadougou because of their importance in the functioning of this ecosystem.
Several samples were taken from both stations based on flood recurrence
areas. The particle size analysis was done using the Robinson’s Pipette method.
Traditional methods of sediment analysis
have been used to measure organic carbon (O.C.), nitrogen (N), and other
chemical properties including pH, organic matter (MO), and C/N ratio.
Statistical analyzes were carried out to assess the differences between the
physico-chemical parameters of the different sampling zones. In the area of
niakamadougou, the lower values in MO were recorded in areas subject to more frequent flooding, thus close to
the watercourse. In the Sinématiali area, lower M.O. values were
recorded in sediments far from the stream.
Total organic matter levels are higher in surface sediments with the lowest
proportions of clay. The results show that the physico-chemical properties of the sediments vary at the level of
the vertical distribution and according to their spatial distribution.
Successive floods have a direct effect on the dynamics of the physico-chemical properties of sediments along the
shore.
