Dynamic model

Definition

A dynamic model is a mathematical representation that describes how a system changes over time, incorporating variables and their interactions to predict future behavior. These models are essential for simulating complex processes, particularly in the context of hydraulic and process modeling, where they help engineers understand how water flows, pollutants move, and treatment processes operate under varying conditions.
