Managed realignment in the Humber estuary: factors influencing sedimentation
… Strategy, with the main aims to create intertidal habitat to replace that which has been lost in other areas of the estuary and to alleviate increasing flood-risk associated with climate change induced sea level rise. Managed realignment is a relatively new method of flood defence that has …

EFFECTS OF ABIOTIC STRESS AND PREDATOR REFUGE ON TERRESTRIAL PREDATOR-PREY INTERACTIONS
… habitats. I investigated the stress of tidal inundation on marsh predators and prey, and their use of vegetation above water as a refuge from submersion. I found that densities of two key predators were more highly correlated with refuge availability than with tidal intensity. Notably, …

Ecological Community Changes and Ecosystem Functioning During Structured Wetland Development
… ecosystem services, including protection from tidal inundation, grazing for livestock, resources for birds and breeding grounds for fish. After a long history of saltmarsh reclamation there is now emphasis on restoration of existing or destroyed saltmarshes to provide dynamic coastal defences …

Impacts of Microenvironment On Distributions and Activities of Bacteria In A Salt Marsh Environment
… mL-1). As evidenced from dye transport studies, tidal inundation flushes and transports the bacterially-enriched infaunal burrow water within the estuary over semi-diurnal tidal cycles. Marsh elevation also contributes to the frequency of tidal flushing of these burrow waters. Rhizosphere …

The Feeding Ecology of Yucatán Black Howler Monkeys (Alouatta pigra) in Mangrove Forest, Tabasco, Mexico
… few species of plants specially adapted to tidal inundation and saline conditions. Mangrove communities are not considered ideal environments for most mammals, especially large-bodied arboreal herbivores, because of the low-diversity, and supposedly, low-quality vegetation. In this study, I …

MEASUREMENT AND MODELLING OF ESTUARINE CHEMISTRY
A l-D tidally resolving hydrodynamic model of the Tweed Estuary has been encoded using the Estuarine Contaminant Simulator, ECoS. The model results of axial and time series variations in water elevation, salinity and turbidity are compared to field data recorded during the LOIS survey programme. …

Spatial analysis of blue carbon in a UK Saltmarsh: Implications of carbon distribution.
… indicating that elevation, controlled by tidal inundation and subsequently establishment of less salt tolerant vegetation, is one of the main controls of organic carbon burial. No correlations were established between organic geochemical results and grain size indicating the latter …

The migration and accumulation of radionuclides in the Ravenglass saltmarsh, Cumbria, UK
… by sediment accumulation associated with tidal inundation frequency and the clay content in the sediments. Surface erosion also plays a major role in redistributing saltmarsh sediment labelled with older Sellafield discharge within the marsh together with the sediments originated from the …

Earthquakes and sea-level change in Hokkaido, north-east Japan
… are zoned with respect to elevation and tidal inundation, and my preferred transfer function (a model that contains 87 samples and 24 taxa) has a prediction r2 of 0.75 and a root mean squared error of prediction of ± 0.32 m. I apply this transfer function to shallow fossil sediment …

Tidal Wetland Inundation and Vegetation Phenology from Space: A Synthesis of Approaches for Characterizing Ecological Status and Inundation Dynamics in Tidal Wetlands with Remote Sensing Observations
… on the monitoring and characterization of tidal marshes using remote sensing-based approaches. Chapter 1 introduces the topics of wetland ecology and remote sensing. Chapters 2-4 are the main research chapters of the dissertation covering the topics of tidal marsh mapping, tidal marsh …

Identifying inundation-driven effects among intertidal Crassostrea virginica in a commercially important Gulf of Mexico estuary
… amounts of uncertainty for coastal species. Intertidal species may be especially affected since they are dependent on daily inundation and exposure. The eastern oyster Crassostrea virginica is an economically and biologically important sessile intertidal species ranging from Canada to the Gulf of …

A HYDROLOGICAL INVESTIGATION OF THREE DEVON SAND DUNE SYSTEMS; BRAUNTON BURROWS, NORTHAM BURROWS AND DAWLISH WARREN
… Northam the drainage ditch network and reduced tidal inundation were the other main factors influencing groundwater levels. At Dawlish the golf course pump drainage system and scrub encroachment were effectively reducing annual groundwater recharge. At Braunton a numerical groundwater flow model …
