Correction: Chen, Y.-C.; Yeh, H.-C.; Wei, C. Estimation of River Pollution Index in a Tidal Stream Using Kriging Analysis. Int. J. Environ. Res. Public Health 2012, 9, 3085-3100

The authors wish to add the following amendments and corrections on their paper published in IJERPH [1]. 1. Page 3093, line 4, " spherical " and " exponential " were corrected instead of sphere and index. The sentence should read " The results obtained were then applied to the theoretical semivariogram models, including power, spherical, exponential, and Gaussian models ". The same situation in page 3095 lines 8, 10, 11 and 12 was also corrected. The sentence should read " According to Table 3, the coefficients of determination from the spherical, exponential, and Gaussian models were higher than those of the power model. An inflection phenomenon occurred in the Gaussian model at the short-distance area, while the spherical model was limited to certain distances. Therefore, in this study, the exponential model was selected to calculate the RPIs for those rivers. Table 4 summarizes the applied results of the exponential model for the 13 h of study along the Tanshui River ". 2. Page 3093, line 6, " estuaries " should be " tributaries ". 3. Page 3093, Figure 5, we add two river kilometers marked at the conjunction of two tributaries Keelung River and Hsintien River which let the readers acknowledge the exact river kilometers at gauging stations along these two tributaries.
