Erratum for “Modeling Dynamic Behavior of Water Distribution Systems for Control Purposes” by Bogumil Ulanicki and Philippe Beaujean

In the fourth paragraph of the “Numerical Results” section, there is an error in the description of Fig. 5. “The day operation is depicted by the dashed line” should be changed to “The day operation is depicted by the top line.”

During composition, an error was introduced in the explanation of vectors following Eq. (18). The complete equation and its explanatory text are as follows:where $\mathrm{\Delta }\mathbf{h}$ = vector of head losses (gains) across all elements; and $\mathrm{\Delta }{\mathbf{h}}_{f-1}$ = vector of the head differences between the reference node and other forced head nodes.
