Thread Content

In the analytical solution of a **-state water quality model for predicting the longitudinal distribution of ammonia nitrogen concentrations in estuaries, the parameter that does not need to be input is ( ). A. Residual flow and residual flow velocity B. First-order decay coefficient C. Longitudinal dispersion coefficient D. Transverse mixing coefficient. Correct answer: D. Explanation: The **-state water quality model is used to predict the longitudinal distribution of concentrations of non-persistent pollutants, and it is independent of the transverse mixing coefficient.

The parameter that does not need to be input when using an analytical solution of a one-state water quality model to predict the longitudinal distribution of ammonia nitrogen concentrations in estuaries is (D). A. Residual flow and residual flow velocity B. First-order decay coefficient C. Longitudinal dispersion coefficient D. Transverse mixing coefficient

In the D one-state water quality model, to predict the longitudinal distribution of ammonia nitrogen concentrations in estuaries using an analytical solution, the parameter that does not need to be input is ( ). A. Residual flow rate and residual flow velocity B. First-order decay coefficient C. Longitudinal dispersion coefficient D. Lateral mixing coefficient

A、－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
Reply #52015-10-10
D, the lateral mixing coefficient, because it is used to determine the longitudinal distribution
