About the product

This book presents a study on the environmental impacts of the controversial Ok Tedi Gold/Copper Mine in Papua New Guinea. The focus is on the effects of large discharge of tailings and waste rock material on riverbed aggradation of the Ok Tedi and Fly rivers. Also covered is the accumulation/redistribution of sediments in the Fly River floodplain and the possible toxic effects on biota and the food chain. It is a valuable reference source for those interested in geomorphological changes through mine waste disposal and the effects of heavy metal rich waste materials on the water quality of rivers.
