WP2 - Development of Behavioural Geomorphic Models

WP2.1 Review and Define Priorities.

The current capability, the needs and realistic goals will be defined for Deliverable 2. This task will involve (1) an assessment of coastal morphology at the coastal feature and element scale, (2) their relevant interactions and coupling between features and elements, (3) the current status of behavioural geomorphic models, and (4) the needs and challenges posed by WP3.1/3.2.

WP 2.2 Behavioural (Reduced Complexity) Landform Model Development

Large-scale coastal and estuary system behaviour presents major modelling challenges, but thinking of them as complex systems provides an opportunity to develop new ways of capturing the interactions between the multiple component landforms and processes. Importantly, and in contrast to bottom-up approaches, this is consistent with the interpretive processes normally used by geomorphologists. Based on the WP2.1 priorities, WP2.2 will generalise and extend existing Reduced Complexity approaches to produce a set of behavioural geomorphic models capable of simulating meso-scale coastal behaviours, including aspects of the interaction between suites of landforms and between open coasts and estuaries.

WP 2.3 Statistical (Data Driven) Model Development

We will develop a collection of methods and models that function consistently within the system framework (WP1.1). This will involve: coding empirical knowledge as a rule or equation where available; flagging gaps in knowledge appropriately; updating existing methods and models to account for variations in sediment type; representing uncertainty; and considering defence interventions. The methods will be assessed for consistency and suitable adjustments and/or rules for application developed to avoid conflicts. Our proposal is to choose a selection of methods that cover equilibrium models and reduced physics models that typically apply to either a profile or plan shape, and extend these to a stochastic description. In addition we will include two data-driven techniques that can be applied to higher dimensional features as well as profiles.

WP 2.4 Geomorphic Model Integration

In WP2.4 we will ensure that the models that are developed in WP2.2 and 2.3 are theoretically and technically compatible. This is a process that will initiate in WP2.1 and will interact closely with WP2.2/2.3 and WP1.4. As models become available they will be tested in realistic (but not real) settings in order to explore interdependencies and emergent properties, before embarking on application and validation at case study locations (WP3.1/3.2).
