Spatial-Seasonal variations of Chlorophyllous biomass (Chlorophyll a) in the Upper Bandama basin of Ivory Coast

Abstract

The concentration of Chlorophyll was studied between October 2017 and September 2018 in the upper Bandama. It follows from
our results that it is higher in the rainy season than in the dry season, especially during the full rainy season (FRS). This increase in
the rainy season is linked to the runoff loaded with nutritious salt from the town of Ferkessédougou and various agrosystems in the region. The L2 and L3 stations of the Lokpoho River and M2 of the Bandama River are the most concentrated in chlorophyll. The Lokpoho River has the highest values of Chlorophyll compared to the Bandama River. This river should be monitored because of its high chlorophyll content which corroborates a rich high in nutrient salt.
