Modelling the future of coastal soft cliffs underchanging climate

在nerc - envisiondoctortrainingpartnership中，博士研究生项目名为“气候变化下沿海软崖的未来建模”，现诚聘博士研究生。海岸软崖是世界范围内海岸环境的重要组成部分。它们的撤退是一个全球性问题，威胁着沿海社区。气候变化影响软崖退缩；然而，需要研究来理解和量化这种影响。要做到这一点，我们还必须理解和模拟软悬崖的物理驱动因素。这个博士项目将开发数值方法来描述软悬崖的未来行为，并分析两个具有代表性的悬崖/海滩系统的案例研究：英国的Happisburgh和美国长岛的Montauk Point海岸。该项目将从分析现有数据开始，结合新的实地工作，澄清和模拟导致悬崖崩溃的物理过程，这些物理过程仍然知之甚少。此后，重点将是设计一种创新技术来模拟这些系统的长期行为。最后，在IPCC的高端排放情景下，对这两个案例中的气候变化对悬崖退缩的影响进行了模拟。

Applications are invited for a PhD studentship within the NERC-ENVISIONDoctoralTrainingPartnership with a project entitled: "Modelling the future of coastal soft cliffs under changing climate". Coastal soft cliffs are extremely important components of coastal environments worldwide. Their retreat is a global problem that threatens coastal communities. Climate change affects soft cliffsretreat; however,research is needed to understand and quantify this effect. To do so, we also must understand and model physical thedrivers offailure of soft cliffs.This PhD project will develop numerical methods to describe the future behaviour of soft cliffs and analysetwo case studies representative of cliff/beach systems worldwide: the Happisburgh (U.K.) and Montauk Point, Long Island(USA) coasts. The project will start by analysing existing data, integrated with new field work,to clarify and model the physical processes driving cliff failure that are still poorly understood. Thereafter, the focus will be on devising an innovative technique to model the long-term behaviour of these systems. Finally, the effect of climate change on cliff retreat in the two casestudieswill be modelled, under high-end emission scenarios of the IPCC.
