From Representative Period Selection to Process‐Based Sediment Dynamics
… in which tides, waves and wind jointly govern sediment transport. Despite its ecological and morphological significance, the region remains comparatively understudied, and its typical residual and storm-driven sediment pathways are poorly understood. This thesis develops an integrated, …

Hypsometric and geometric controls on hydrodynamics, tidal asymmetry, and sediment connectivity in shallow estuarine systems
… between tides, meteorological forcing, and sediment transport processes. This thesis focuses on the fundamental links between these physical processes, and the geomorphologic characteristics of shallow estuarine systems, specifically: (i) how shallow basin geometries and hypsometries affect …

Assessing Dynamic Seabed Change on the Scottish Continental Shelf
The dynamics of sediment bedforms mobilised by modern day coastal fluid mechanics can reduce the lifespan of offshore construction by modifying the foundational stability for offshore projects such as wind turbines and subsea cables. Dunes represent wave-like bedforms that range in size and …

Accumulation of sediment and radionuclides in tidal marshes of the Murderkill River Estuary, Delaware
This thesis examines patterns and rates of sediment accumulation and tidal marsh accretion in the Murderkill River estuary, Delaware, with special emphasis placed on changes in accumulation rates and sediment physical properties associated with historical land-use practices, such as mosquito …

The application of historical data and computational methods for investigating causes of long-term morphological change in estuaries : a case study of the Mersey Estuary, UK
… perturbation. Changes to tidal flow and related sediment transport patterns outside the estuary resulting from training wall construction are examined with regard to the stability of the estuary system. The results from computational hydrodynamic models representing the years 1906, 1936 and 1977 …

The development of dual signature, fluorescent magnetic sediment tracing technology
The erosion, transport and deposition of sediment create environmental problems and social issues worldwide. Due to these ecological, environmental and economic implications for society, the importance of protecting and managing the sediment and soil resource is increasingly recognised through …

The evolution of tidal coastal landscapes and the controls on pathways to equilibrium
… focused on the roles of initial bathymetry, bed sediment and mud concentration at open boundaries on shaping equilibrium profile development of tidal basins. The results of the model showed that geomorphological development (long-term evolution) is similar in sandy environments with different …
