A detailed characterisation of the wave climate around New Zealand and its variability
(The University of Waikato, 2018)Ocean waves can cause severe social and economic impacts. Therefore, understanding their behaviour is of paramount importance for the effective management of coastal and ocean hazards. This thesis thoroughly investigates ... -
The Amplification of Tsunamis by Mercury Bay, New Zealand
(University of Waikato, 2012)The east coast of New Zealand is exposed to tsunami hazards, which are generated by both distant and near tsunamigenic sources. The impact of tsunami varies along the coast depending on the source region and the amount of ... -
Attenuation of tides and storm surges in coastal mangroves
(The University of Waikato, 2021)Mangrove forests have been shown to provide coastal protection by reducing waves, moderating currents, stabilizing sediments, and lessening storm winds. However, the interaction between storm surge and mangroves is less ... -
Dispersal and mixing of stormwater run-off plumes in the Port of Tauranga, New Zealand
(University of Waikato, 2015)Buoyancy differences between two water bodies can often dominate flows such as stormwater discharge or river plumes in the coastal environment. The buoyancy difference usually arises due to differences in salinity, ... -
Ecological effects of turbidity variations in and around dredging areas in the Port of Tauranga
(The University of Waikato, 2018)Turbidity is the scattering of light in water bodies and is an important measurement for assessing water quality in coastal systems. Suspended particles in the water column can greatly impact on light penetration and ... -
The ecological role of the suspension feeding bivalve, Austrovenus stutchburyi, in estuarine ecosystems
(University of Waikato, 2011)Suspension feeding bivalves are described as key species in many aquatic ecosystems, where they can influence primary productivity and nutrient dynamics, are food for higher trophic levels, and may be harvested in commercial ... -
Effect of exposure on the erodibility of intertidal mudflats
(The University of Waikato, 2021)Sediments on intertidal flats are exposed during low tides. Under the effect of exposure, the water content of sediments decreases because of the evaporation process, which alters the erosive behaviour of cohesive sediments, ... -
Effects of surfzone wave transformation on swash dynamics
(University of Waikato, 2012)Swash oscillations on two natural beaches were measured to show that the shape and magnitude of energy spectra can be largely dependent on processes occurring inside the surfzone. The observations took place on a steep, ... -
Episodic, seasonal, and long term morphological changes of Coromandel beaches
(The University of Waikato, 2010)The Coromandel Peninsula was subject to subdivision and development primarily since the 1960's. Much of the development that has occurred now renders protection from the existing beach systems which have typically been ... -
Hydrodynamic and sediment transport numerical modelling and applications at Tairua Estuary, New Zealand
(University of Waikato, 2014)Tairua Estuary is a partially mixed estuary located on the east coast of the Coromandel Peninsula, North Island, New Zealand. Like many estuaries worldwide, Tairua Estuary is experiencing rapid sedimentation, which is ... -
Hypsometric and geometric controls on hydrodynamics, tidal asymmetry, and sediment connectivity in shallow estuarine systems
(The University of Waikato, 2022)Estuaries and tidal basins are highly dynamic coastal systems that serve as a transition zone between the river and the ocean. The morphological evolution of these diverse environments is modulated by non-linear feedbacks ... -
Hypsometry of New Zealand estuaries
(University of Waikato, 2015)Estuarine morphology is constantly changing because of continual sediment transport mainly driven by tidal asymmetry and wind waves. For modelling purposes, intertidal areas have often been simplified to relatively ... -
Investigating groundwater derived nutrient fluxes within Tauranga harbour, New Zealand
(The University of Waikato, 2021)Submarine groundwater discharge (SGD) is one of the key pathways that connects land and ocean, delivering freshwater, nutrients, carbon, metals, and other chemical constituents to coastal waters. In New Zealand, local Māori ... -
Measuring and modelling estuarine macroalgae blooms and water column nutrients
(University of Waikato, 2016)This thesis examines the dynamics of estuarine macroalgae blooms of the genus Ulva and the environmental factors controlling them, using process-based mathematical models as well as observation data from Tauranga Harbour ... -
Modelling of low- and high-frequency sea level variability and their drivers around the southern African coast
(The University of Waikato, 2020)Recent surveys indicate that marine operational forecasting is becoming increasingly important due the pressure to manage impacts associated with our changing climate. The methods with which forecasts are being produced ... -
Modelling the long-term morphological evolution of tidal embayments
(University of Waikato, 2011)A numerical model was developed to improve the understanding of the long-term morphological evolution of tidal embayments. Morphological change was simulated as a result of the interactions between hydrodynamics, sediment ... -
Morphodynamics of Ebb-Tidal Deltas
(University of Waikato, 2015)The purpose of this study was to learn more about the significant drivers of ebb-tidal delta morphology using observational methods and fundamental physical relationships between forcing conditions and morphological response. ... -
Nitrogen yields into the Tauranga Harbour based on sub-catchment land use
(University of Waikato, 2013)Changes in land use and management practices can have significant impacts on freshwater, estuarine and marine environments. In order to preserve the economic, cultural, recreational, and ecological value of these environments, ... -
Nutrient dynamics in shallow tidally-dominated estuaries
(University of Waikato, 2011)Te Puna and Waikareao estuaries are shallow tidally-dominated estuaries in Tauranga Harbour located on the Bay of Plenty Coast, New Zealand. Tauranga Harbour is the site of a large commercial port surrounded by urban ... -
Remote coastal monitoring of beach usage on Tairua Beach
(The University of Waikato, 2021)Research that gathers data from public reporting is susceptible to population bias, which arises from a lack of knowledge on the probability of a person’s ability to witness an event. Data collection based on public reporting ...
