Effects of thermal stratification on the concentration of iron and manganese in a Tropical Water Supply Reservoir

Thermal stratification in lakes is an important natural process that can have a significant effect on the water resource quality. The potential changes in chemical contents in water resulting from stratification are the production of ammonia, sulphides and algal nutrients and the increasing concentr...
