Supplementary Figure 1 | CWT scalograms: a-h - of the time series no. 6-13 from Table 1 (the
horizontal axes represent the number of consecutive measurements, 96 per day); i-p – of
selected 3000 consecutive measurements (96 per day) from the time series no. 6-13 from Table
1; the thick black contours represent the 0.95 confidence level against AR1 red noise; the
colours with lighter shade of the power spectrum represent temporal areas affected by edge
effects.
Supplementary Figure 2 | Periodograms of the time series no. 6-13 from Table 1, extracted from
Supplementary Fig. 1.i-p scalograms (the frequency represents cycles per number of
measurements).
Supplementary Figure 3 | Selected short time series extracted from the time series no. 6-13 from Table 1 (a-h); periodograms of the GWS values extracted from PWC scalograms of the a-h time series (i-p) (the frequency represents cycles per number of measurements).
Supplementary Figure 4 | Scalograms of the City of Conroe piezometer during April – August 2013 for raw data (a) and, respectively, simple derivative data (b).
Number of measurements (24 per day)
Supplementary Figure 5 | WTC analysis of Leona River near Uvalde (gauge height) and Uvalde piezometer (deep to water level) during 2013 (raw data).
Supplementary Figure 6 | Scalograms of The Ranch piezometer during 2012 for raw data (a)
and, respectively, simple derivative data (b).
Number of measurements (96 per day)
Supplementary Figure 7 | WTC analysis of Bogan River at Dandaloo (gauge height) and Trangie piezometer (deep to water level) during 2013 (raw data).
Supplementary Figure 8 | CWT scalograms of: a - Blue River (October 2003 – December 2013);
b – Clear Fork Trinity River (January 1991 – December 2013); c – Middle Wichita River (June
1994 – September 2011); d – Panther Brook at Gosling (January 1999 – December 2013); e –
White River (October 1993 – December 2013).
Supplementary Figure 9 | Comparison between the semidiurnal signal detection in scalograms
using raw Medina River gauge height (a) and discharge (b) data (96 measurements per day;
2007-2013); gauge height (c) and discharge (d) data after applying detrending, simple
differencing, double smoothing at ¼ of a day and median filtering at ¼ of a day.
