*3.7.4.1 Hydrodynamic models*

These models simulate water movement, flow patterns, and circulation within aquatic systems. They help understand how phosphorus is transported through water bodies and how it interacts with sediment and other components.

#### *3.7.4.2 Water quality models*

Water quality models integrate hydrodynamics and biochemical processes to simulate nutrient dynamics, including phosphorus concentrations. These models consider factors like nutrient uptake, sediment interactions, and biological processes that influence phosphorus levels.
