Erratum to: Environmental Management (2014) 54:1267–1287 DOI 10.1007/s00267-014-0361-4

Unfortunately, the term “LW” has been missed in Eq. 4 of the original article. In addition, the letters “S” in the first “SW” and “W” in the first “Gw” were published in lower case incorrectly in Eq. 4.

The above mentioned three errors are corrected with this erratum. The correct Eq. 4 should read as:

$$ PV = SW\sum\nolimits_{s = 1}^{11} {Sw} + LW\sum\nolimits_{L = 1}^{8} {Lw} + GW\sum\nolimits_{G = 1}^{4} {Gw} $$
