The main goal of the First workshop on Mixing in Coastal Waters, Rivers & Atmosphere is to provide an opportunity to exchange the developments on studies related to mixing and develop a framework to build new collaborative studies. The First Symposium on Mixing in water-Bodies and Atmosphere will cover research and papers related to river and large-scale lake and ocean-mixing phenomena, industrial outfalls, discharges into the atmosphere, and oil spills in water bodies.
