Dynamics of Dissolved Oxygen in Relation to Saturation and Health of an Aquatic Body: A Case for Chilka Lagoon, India

Figure 2

Figure representing the relationship between the parameters 𝑎, 𝑏, and 𝑐 and the existence of equilibrium solution. In Region I and II, the system admits unique equilibrium. The system admits no equilibrium in Region III. The magnitude of equilibrium DO is higher in Region I when compared to Region II. This is due to domination of the processes present in 𝑐 over the processes that are involved in 𝑎 and 𝑏.
