Tides are one of the most persistent forces on our planet. Tides influence coastal flooding and erosion, navigation, sediment transport, mixing and dissipation. Therefore, any changes to tides have wide ranging implications. Changes in tides are known to have occurred over thousands of years and longer, but tides have generally been considered to have been a stationary phenomenon over centennial time-scales. However, an increasing body of evidence demonstrates that there have been significant changes in tides over at least the last 150 years at a number of locations worldwide. Furthermore, several studies indicate that tides will alter considerably over the 21st Century and beyond in response to future mean sea-level rise. There is currently, however, a crucial lack of understanding of why widespread changes in tidal levels have occurred over the last 150 years with relatively small variations in water depth. The overall aim of this PhD will be to undertake an ambitious, integrated and ground-breaking assessment of future changes in tides on global and local scales.
Objective 1 is to accurately predict future changes in tides using a suite of global numerical models. Objective 2 will be to assess changes in future tides from the models at global coastal mega cities around the world. Objective 3 will focus on changes in tides around the UK. The PhD candidate will undertake a detailed analysis, on a local estuary scale, to assess how climate, and other anthropogenic changes (e.g., dredging) are likely to influence tides and extreme sea levels at this location.
