Soil displacement and net production of sediments from fields with different soil textures in the Ruisseau Ewing watershed and Rivière aux Brochets subwatershed can be quantified by measuring the spatial redistribution of 137Cs and 210Pb. The 13C signature of suspended solids (SS) can be compared with that of potential SS sources (cultivated fields, meadows, woods, river banks) to quantify the relative contribution of these sources to SS loads. This study is one of a series of projects conducted by IRDA and its partners in the Missisquoi Bay watershed in recent years.
