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).
