1 Erratum to: Stoch Environ Res Risk Assess (2014) DOI 10.1007/s00477-014-0902-7

In the original article in the text paragraph under Fig. 2 the mean clustering coefficient values listed were incorrect. The correct version is:

“The mean clustering coefficient of the entire network is 0.67 and 0.70 for these two cases, respectively.”

Everything else in the article remains correct.
