Correction

In the publication of this article (Iwahashi et al. 2018), there was an error in Table 3 in terrain group 10, 11 and 12.

Table 3 CRa and SCb of geomorphological and geological units for each terrain group in Japan

The error: “natural level”.

Should instead read: “natural levee”.

This has now been updated in the original article (Iwahashi et al. 2018).
