The number of deaths attributed to natural hazards continues to rise, despite progress in implementing disaster risk reduction strategies. From 1990 to 2019, more than 1.7 million people died in internationally reported natural hazards. Despite the efforts to address sustainable development goals on climate change and to implement risk reduction strategies and promote hazard awareness in vulnerable areas, more research is needed to build improved resilience in affected communities and to limit the scale of impacts from climate-related hazards and disasters. This Cross-School, multidisciplinary project will open new research opportunities to explore the scales of impact and legacy from catastrophic coastal events, such as large-scale storms and tsunamis, through innovative investigations of coupled hydrodynamic, hydrogeological and morphodynamic sedimentary processes within affected coastal regions and the resulting socio-economic and environmental impacts on vulnerable communities. The study will combine controlled laboratory-based experiments with the interpretation of sedimentary and groundwater data from affected coastal sites to identify process analogues and signatures within coastal sediment deposits, thus aiding the recognition and characterisation of the “region of impact” from historic and pre-historic coastal storm and tsunami events.

The specific objectives include:

  1. To develop new hazard assessment frameworks to determine the scale of risks impacts from the future occurrence of these types of devastating coastal events.
  2. To develop new guidelines by which the resilience of vulnerable coastal communities to short-term shocks (i.e. individual tsunami or storm events) and the longer-term legacy from environmental change (i.e. rising sea levels, increasing storm frequency and magnitude) can be enhanced.
  3. To improve physical understanding of the underlying interactions between tsunami and/or storm hydrodynamics and the sedimentary, hydrogeological and morphological response of the coastal margins affected, especially in the nearshore region.
  4. To inform other related risks from these events such as (i) increased likelihood of saline intrusion into drinking water supplies (surface waterbodies and aquafers), (ii) impacts on critical infrastructure, and (iii) increased risks of waterborne diseases.

The proposed methods will combine research at different spatial scales: experimental measurements within scaled, controlled laboratory simulations will be coupled with detailed field measurements at an analogue site in the UK (e.g. Montrose basin) and analysis of data from international sites of interest (e.g. South China Sea, Pacific Ocean) where the impacts from historic/prehistoric coastal events can be identified and quantified. Within the experimental studies, physical interactions between the hydrodynamic, sediment transport, morphodynamic and hydrogeological process initiated by these catastrophic coastal events will be studied. These laboratory simulations will be conducted within existing and new experimental facilities (i.e. tsunami wave basin and tidal inlet facility) in the Environmental Fluid Mechanics laboratory of SSEN. It is proposed that the field studies and data interpretation will take place for UK and international coastal sites (see above) where past extreme events are known to have occurred.
