Observations of asymmetry in contrasting wave‐ and tidally‐dominated environments within a mesotidal basin: implications for estuarine morphological evolution
TL;DR: In this paper, a combination of hydrodynamic measurements and sediment deposition records was used to determine the conditions under which observed waves are morphologically significant, in which case they influence tidal and suspended sediment flux asymmetry and subsequently infilling over geomorphic timescales.
Storm fine sediment flux from catchment to estuary, Waitetuna-Raglan Harbour, New Zealand
TL;DR: In this paper, the authors examined the timing of sediment delivery from the Waitetuna catchment (167 km2) to its estuary (an arm of the Raglan Harbour, New Zealand) for a single large (10-year return period rainfall) storm.

Field studies of estuarine turbidity under different freshwater flow conditions, Kaipara River, New Zealand
TL;DR: In this paper, the authors present a first interpretation of three days of measurements made in 2013 from the tidal reaches of the Kaipara River (New Zealand) under both low and high freshwater inputs and a neap tidal cycle.

TL;DR: This article showed that potential mangrove habitat (i.e., intertidal area above MSL) is well predicted by an exponential relationship with the ratio of catchment annual sediment load to estuary tidal-prism volume.

Trapping and episodic flushing of suspended sediment from a tidal river
Mark Pritchard,Malcolm O. Green +1 more
TL;DR: In this paper, the authors used a 2-month data set from a mooring in a tidal river that drains into a large drowned-river-valley estuary (Kaipara Harbour, New Zealand) to investigate interactions between tidal-current asymmetry and gravitational circulation.
