Relatively little systematic research has been conducted on the turbulence characteristics of small estuaries. In the present study, detailed measurements were conducted in a small subtropical estuary with a focus on turbulent flux events. Acoustic Doppler velocimeters were installed in the mid-estuary at fixed locations and sampled simultaneously and continuously for 50 h. A turbulent flux event analysis was performed for the entire data sets extending the technique of Narasimha et al. (Phil… 
TURBULENT MIXING AND TURBULENT EVENTS IN BREAKING BORES
A breaking tidal bore is a highly turbulent transient process that may affect the natural estuarine system. Like many natural process flows, the tidal bore flow motion is dominated by coherent
Turbulence and turbulent events in tidal bores: field observations
A tidal bore is a compressive wave of tidal origin, propagating upstream as the tidal flow turns to rising when a macro-tidal flood flow enters a funnel shaped river mouth with shallow waters. New
Field Measurements of Unsteady Turbulence in a Tidal Bore: the Garonne River in October 2013
ABSTRACT A tidal bore is an unsteady rapidly-varied open channel flow generated by the swift advance of the early flood tide in a funnel-shaped river estuary when the tidal range exceeds 4.5 to 6 m.
A note on burst event detection in unsteady natural flows
Turbulent bursting events play a major role in natural systems in terms of sediment scour, transport and accretion as well as contaminant mixing and dispersion. The "bursts" were extensively studied
Coupling between free-surface fluctuations, velocity fluctuations and turbulent Reynolds stresses during the upstream propagation of positive surges, bores and compression waves
In open channel, canals and rivers, a rapid increase in flow depth will induce a positive surge, also called bore or compression wave. The positive surge is a translating hydraulic jump. Herein new
Novel Power Law of Turbulent Spectrum
This paper is concerned with novel power law of turbulent energy spectrum and the relevant experiment in tidal current. The power law in the inertial sub-range has been proposed in such a way that
The Nature of Economic Turbulence: The Power Destructing Economies, with Application to Shipping
Studying the history of “economic turbulence”, we ended up with the certainty that the statistical methods used so far, by economists, are unsuitable to model it. We have mainly the methods of Normal

Turbulence and Turbulent Flux Events in a Small Subtropical Estuary
In natural estuaries, scalar diffusion and dispersion are driven by turbulent momentum mixing. To date, relatively little systematic research was conducted on the turbulence characteristics of small
A Fundamental Study of Turbulence and Turbulent Mixing in a Small Subtropical Estuary
The flow of water in natural systems such as estuaries is a turbulent process, with Reynolds numbers greater than 105. Understanding the turbulence properties of an estuary is important for the
Turbulent measurements in a small subtropical estuary with semidiurnal tides
Since predictions of scalar dispersion in small estuaries can rarely be predicted accurately, new field measurements were conducted continuously at relatively high frequency for up to 50 h (per
Mean and Turbulence Characteristics in a Tidal River
Simultaneous measurements of longitudinal and vertical components of instantaneous velocities and salinities have been performed continuously during two spring tides in the Ota River estuary.

TLDR
An episodic description of the turbulence flux in the time domain enables us to identify separately productive, counter-productive and idle periods (accounting, respectively, for 36, 15 and 49% of the time), taking as criterion the generation of the momentum flux.

In natural systems, mixing is driven by turbulence, but current knowledge is limited in estuarine zones where predictions of contaminant dispersion are often inaccurate. A series of detailed field
