Physical models are not typically used in water quality modeling, as they are more commonly used in other fields such as fluid dynamics and engineering.

Water quality models can be used for a variety of purposes, including predicting future water quality conditions, assessing the impact of pollution on water quality, and designing and evaluating water quality management strategies.

Land use data is not typically a common data requirement for water quality modeling, as it is more commonly used in other types of environmental modeling such as land use planning and watershed management.

Validation is the process of comparing model predictions to observed data to assess the accuracy of the model.

Floodplain mapping is not typically a common application of water quality modeling, as it is more commonly used in other types of environmental modeling such as flood risk assessment and watershed management.

Calibration is the process of adjusting model parameters to improve the agreement between model predictions and observed data.

Groundwater models are not typically considered to be a type of water quality model, as they are more commonly used to simulate the movement of groundwater and the transport of contaminants in groundwater.

Sensitivity analysis is the process of assessing the uncertainty in model predictions by varying the input parameters of the model and observing the resulting changes in the model outputs.

Analytical models are not typically used in water quality modeling, as they are more commonly used in other fields such as mathematics and physics.

Verification is the process of ensuring that a model is correctly implemented and that the input data is accurate.

Land use models are not typically considered to be a type of water quality model, as they are more commonly used to simulate the changes in land use over time and the impact of land use on the environment.

Simulation is the process of using a model to make predictions about future water quality conditions.

Ecological models are not typically considered to be a type of water quality model, as they are more commonly used to simulate the interactions between organisms and their environment.

Model selection is the process of selecting the most appropriate model for a particular application.

Economic models are not typically considered to be a type of water quality model, as they are more commonly used to simulate the economic impacts of water quality management decisions.
