The Radovna River's color is likely due to a combination of factors, including:
Minerals
When rocks weather down, minerals like calcium carbonate, iron, and manganese are released into the water, which can cause different colors.
Microscopic clay particles
These particles can be washed into the river during rain events from shale outcroppings.
Algae
The presence of algae in the water can make a river look green. Phytoplankton, a microscopic plant-like organism, contains chlorophyll, which absorbs red and blue light, leaving green as the dominant color. The more phytoplankton in the water, the greener it will appear. |
