Description: An important environmental impact on running water
        ecosystems is caused by hydropeaking - the discontinuous
        release of turbine water because of peaks of energy demand. An
        event-based algorithm is implemented to detect flow
        fluctuations referring to increase events (IC) and decrease
        events (DC). For each event, a set of parameters related to the
        fluctuation intensity is calculated. The framework is
        introduced in Greimel et al. (2016) "A method to detect and
        characterize sub-daily flow fluctuations"
        <doi:10.1002/hyp.10773> and can be used to identify different
        fluctuation types according to the potential source: e.g.,
        sub-daily flow fluctuations caused by hydropeaking, rainfall,
        or snow and glacier melt. This is a companion to the package
        'hydroroute', which is used to detect and follow hydropower
        plant-specific hydropeaking waves at the sub-catchment scale
        and to describe how hydropeaking flow parameters change along
        the longitudinal flow path as proposed and validated in Greimel
        et al. (2022) <doi:10.1002/rra.3978>.
