Environmental–Aquatic Biota Interactions

The relationship between the aquatic environment and the organisms that inhabit it is a unique and important area of research. This uniqueness is reflected in the way different aquatic species respond to changes in their environment. These responses represent the organisms' natural adaptation mechanisms. Each species exhibits a different level of sensitivity to environmental change, and even individuals of the same species may respond differently depending on the magnitude and duration of the environmental disturbance.

Modeling technology provides an effective tool for investigating interactions between environmental conditions and aquatic organisms. The first step is to identify how target organisms respond to changes in their environment. The second step is to use numerical models to simulate changes in the physical, chemical, and biological characteristics of the aquatic environment. Modeling scenarios are developed based on potential variations in these environmental conditions and their expected effects on the behavior, distribution, and survival of aquatic organisms. The simulated environmental changes are then analyzed together with observed or predicted biological responses to better understand the relationships between habitat conditions and aquatic life.

The Hydrodynamic Model is used to simulate current circulation patterns and water level variations, while the Advection–Dispersion Model predicts the transport and distribution of chemical and biological constituents that influence aquatic organisms. The Coastal Morphology Model is particularly important in areas where shoreline morphology is unstable or has been altered by human activities. Because particle transport is closely linked to coastal morfological changes, the Particle Tracking Model is also applied to evaluate sediment and particle movement. In ecosystems with complex interactions among physical, chemical, and biological processes, the Ecosystem Model is used to simulate these integrated relationships. Finally, the Marine GIS Model combines all simulation results with field observations and supporting spatial information into a comprehensive geographic information system, enabling efficient visualization, interpretation, and decision-making.
