a Comparison between RMS noise amplitude at station N.MKGH (gray) and streamflow of the Seki River at Futagojima monitoring station (blue) in the period from 1 January 2011 to 31 December 2013. The measurement scales of the RMS noise amplitude and the streamflow are given by the right and left ordinates, respectively. The area with a gray background indicates a period of recording system errors. b As for Fig. 5a, but for 1 April 2012 to 31 May 2012, indicated by a black rectangle in Fig. 5a
