Measured And Simulated Concentrations Of Cod Components And Total Download scientific diagram | measured and simulated concentrations of cod components and total sulfide in water phase, kawasaki town, december 4, 1996; wastewater temperature: 14 to 15 °c. from. Based on the three identified specific wavelengths, the multiple linear regression (mlr) method was adopted for the cod estimation modeling. a comparison between the predicted cod concentrations and the true cod concentrations is shown in fig. 4. the model performance was evaluated by the criteria of rmsre and rev . compared with the value of.

Measured And Simulated Concentrations Of Cod Components And Total First, linear regression analysis and correlation analysis between tn, tp, cod concentrations and the proximal remote sensing surface reflectance were determined to find the sensitive band (fig. 4). good correlations were observed between the in situ measured tp and cod concentrations and proximal remote sensing surface reflectance at 700–800 nm. The effluent cod was quite stable around 30 mg l as shown in figure 3, and remained unaffected by the fluctua tions in the influent as well as by the variations in dissolved oxygen concentrations. Measured concentrations of cod, nh 3 n, and bod 5 were selected for each month from january to december 2019 to compare with the corresponding simulated concentrations, and the water quality. Pollutant concentrations were measured by triplicate standard laboratory analyses for tss (nf t90 105 2, 1997) and total and filtered cod (iso 15705, 2002). average concentrations, standard uncertainties, pre treatment of spectra and outliers detection were carried out according to the methods presented in lepot et al. (2013) .

Measured And Simulated Concentrations Of Cod Components Do And Tota Measured concentrations of cod, nh 3 n, and bod 5 were selected for each month from january to december 2019 to compare with the corresponding simulated concentrations, and the water quality. Pollutant concentrations were measured by triplicate standard laboratory analyses for tss (nf t90 105 2, 1997) and total and filtered cod (iso 15705, 2002). average concentrations, standard uncertainties, pre treatment of spectra and outliers detection were carried out according to the methods presented in lepot et al. (2013) . The performance of the developed model was evaluated by comparing the measured and the simulated effluent concentrations of the four components, i.e. s no, s nh, total cod (cod t) and tn. the simulated effluent concentrations of s no and s nh were directly obtained by solving the model system, while the total cod and tn were evaluated as below. The organic matter related water quality was substantially recovered after joining the effluent (st. 17) from the daecheong reservoir, presenting the average bod and cod concentrations of 2.3 mg l and 7.6 mg l, respectively. total nitrogen concentrations in the watershed exhibited similar spatial variations, ranging from 1.8 mg l to 20.0 mg l.
