%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).
