Mean concentrations of Chlorophyll-a (Chl-a, mg m-3), particulate organic carbon (POC, mg L-1), particulate nitrogen (PN, mg L-1) and total suspended mater (TSM, mg L-1) in upper and lower reaches of the Godavari River during (a) low flow period and (b) high flow period. Concentrations of POC and PON were shown on the right side y-axis and the remaining parameters were shown on the left side y-axis.
