Streamflow properties during low and
high frequency scales using information and complexity
measures
Depicted in Fig. 5 the computation results for the information and
complexity metrics evaluated for the studied stations during low
frequency scales. Apparently, the information metrics findings (Fig. 5
(a, b)) show the presence of two scaling regimes for the examined
discharge records. The first scale has a very steep upward trend at
short times up to AL=20 hours approximately (zoomed in Fig. 7c),
whereas, the second upward trend has a mild slope for longer times. In a
similar manner, the complexity contents show a comparable behavior, i.e.
in the case of effective measure of complexity (Fig. 5 (c)), a sharp
downward trend at short aggregation lengths followed by a moderate slope
which is identically opposite to the results of the information
measures. On the other hand, the estimate results of the fluctuation
complexity (Fig. 5d) have a shape of \(\bigwedge\) peaked roughly at AL
≈ 10-15 hours (see Fig. 7d), with a gradual descending at long ranges
(Fig. 5d).
