The Oxygen content of a body of water has a very direct relationship to the geographical topography of the area. If the geography of the area contains many elevation changes (i.e. waterfalls or rapids) the water tends to bemore oxygenated. This works by the air being churned into the water therefore adding Oxygen the water. If the geography of the water body is flat, then the Oxygen content will most likely be less.
Another important way the topography of an area affects water’s Oxygen content is the amount of vegetation present within the water body. Plant life helps maintain excellent Oxygen levels that lead to good water quality. This goes to show that even the underwater topography of an area can impact an aquatic environment.
