摘要:

The January, 1970, Journal AWWA (Vol. 62, No.1), contained errors in two articles. In the article, “Analysis of Circular‐Cylindrical and Conical Concrete Containers by Finite Differences,” pp. 47‐50, by Amin Ghali, Table 1 and Figure 1 were incorrect. In the article, “Generalizing Dry‐Day Frequency Data,” pp. 51‐54, Equation 2 was incorrect. Both mistakes are corrected here.
