Erratum to: SpringerPlus (2016) 5:107 DOI 10.1186/s40064-016-2714-3

Upon publication of the original article (Dang and Park 2016), it was noticed that the ‘Competing interests’ section was inaccurate. This has now been corrected in this erratum. Instead of:

“We received support from the Institute for Disaster Prevention, Gangneung-Wonju National University, South Korea.”

The text should read:

“This work was financially supported by a Grant (Code#’08 RTIP B-01) from Regional Technology Innovation Program funded by Ministry of Land, Transport and Maritime Affairs of Korean government.”

Furthermore, throughout the text, the word “Asungjun” should instead read “Eosungjun.” For example:

“The Asungjun River section of the mountainous Yangyang Namdae River (South Korea)” should read: “The Eosungjun River section of the mountainous Yangyang Namdae River (South Korea).”
