Identifying coastal archaeology using multispectral satellite imagery of the intertidal zone

Project partners:
Coastal & Estuarine Research Unit, UCL
Langelands Museum Remote Sensing Unit
Hampshire & Wight Trust for Maritime Archaeology
Centre for Archaeology, Anthropology & Heritage, Bournemouth University

Funding: English Heritage (2008-2010) Status: completed.

Project description:
This project is a desk-based assessment to test the value of using multispectral high-resolution data to examine intertidal archaeology and morphology. The project takes advantage of recent advances in remote-sensing technologies and GIS spatial mapping capabilities to identify archaeological features, integrate a wide range of archaeological, morphological and palaeoenvironmental data, and to reconstruct the coastal prehistory of the Solent, on the southern coast of England. The project focuses on the development and assessment of the multispectral mapping technique, which has the potential to provide a cost-effective approach for monitoring, mapping and managing the coastal zone and their related archaeological sites, particularly in regions of significant human activity.



Characterisation and prediction of large-scale coastal geomorphological behaviour

Alnmouth_cmap.jpgFunding: Environment Agency SC060074 (2007-2009)  Status: ongoing

This work is funded by Environment Agency and aims to develop knowledge, models and analysis methods that characterise the exchanges taking place over large temporal and spatial scales within the coastal system. Specific project objectives of this project are:

1. To scope and develop a detailed research plan including consultation, reviewing and understanding the processes and models available for assessing and predicting coastal morphological change and responses.

2. To characterise large scale coastal exchanges to allow models over different scales and components of the coastal system to be linked so that a more integrated approach to predicting impacts can be developed.

3. To develop a conceptual coastal geomorphological behavioural model to predict large-scale long-term coastal geomorphological change to enable predictions of future coastal behaviour incorporating coastal intervention.

The project consortium includes HR Wallingford, UCL, University of Southampton, University of Newcastle, Kenneth Pye Associates, Royal Haskoning and British Geological Survey. An important component of this project has been the formalisation and development of a method for mapping the structure of large-scale coastal systems.

Development and demonstration of systems-based estuary simulators (EstSim)

Funding: Defra FD2117 (2004-2007)  Status: ongoing


The EstSim consortium includes ABPmer, UCL, University of Plymouth, Discovery Software Ltd, and HR Wallingford. CERU's role involves work on the computational basis of qualitative behavioural system models; software architectures for the development of a simulator that can form part of the broader set of estuary modelling tools developed under ERP2; development and testing of a Boolean network-based prototype simulator against generic UK estuary types and case studies of the Ribble Estuary and Southampton Water.his work is funded by Defra under Phase 2 of the Estuaries Research Programme (ERP2). The aim is to extend our ability to simulate the morphological response of estuaries through the delivery of research into a systems-based behavioural modelling methodology. Qualitative mathematical of this kind provides an alternative yet complementary methodology to more conventional modelling methodologies being researched within the other ERP2 projects (which encompasses morphological concepts, and bottom-up, top-down and hybrid modelling approaches). EstSim will also explore the simulation process in order to facilitate knowledge exchange between the systems-based tools and estuary managers.

Historical Evolution of the Suffolk-Essex Shoreface and Inner Shelf

Funding: Crown Estate / National Maritime Museum (2007-2008)  Status: ongoing


This project is being undertaken through a Caird Research Fellowship awarded to Dr Helene Burningham in 2007 by Crown Estate, in partnership with the National Maritime Museum. The extensive marine chart and map collections of the National Maritime Museum and Crown Estate constitute an important resource that can be utilised to understand the historic evolution of the East Anglian coast.

Historical bathymetric charts covering the Suffolk and Essex shoreface and inner shelf have been scanned and georeferenced to facilitate GIS-based analysis of morphological changes in major features of interest (e.g. shorelines and offshore sand banks). When completed, this study will provide an historical context for contemporary coastal process studies and shoreline management.

Morphodynamics and sedimentology of mixed-sediment inlets

Status: ongoing

Inlet research has tended to focus on sandy systems and mixed sand-gravel inlets have only recently been scientifically described. Also, the relative importance of wave and tidal processes is generally used to account for geographical variation in inlet morphodynamic behaviour despite the fact that sedimentology also exerts an important control on the efficacy of transporting mechanisms and the morphology of inlet shoals. CERU has studied two sand-gravel inlets on the east coast of England to evaluate the relative importance of sedimentology on inlet and ebb-tidal delta morphodynamic behaviour.

deben3d_91-03_edit.gifWoodbridge Haven at the mouth of the Deben estuary maintains a fixed inlet position 8 km to the south of Orford Haven, the more mobile mouth of the Alde/Ore estuary. Woodbridge Haven bypasses sediment through ebb-tidal breaching, whilst bypassing at Orford Haven occurs through a combination of long-term alongshore inlet migration and spit breaching with short-term ebb-tidal breaching. Both systems comprise sand and gravel-sized sediment, and are subject to a similar North Sea storm wave climate and meso-tidal regime. Whilst these inlets can be conceptualised in a similar way to their sand-dominated counterparts, their morphometry and periodicity are not directly comparable: they are smaller and bypass sediment more slowly than would be expected for sand-dominated systems of comparable size.

Capturing geomorphological change in a coastal simulator

Funding: Tyndall Centre - Research Project T3.42 (2003-2005)  Status: completed

tyn_coast_simulator.jpgThis project was funded through the Tydnall Centre'sResearch Theme 4 - Sustaining the Coastal Zone Project ID - T3.42 and involved a consortium of Southhampton University, Tyndall Centre, British Geological Survey, UCL, and the University of Cambridge. It has led to an outcome-driven deductive methodology for geomorphological analysis that structures current knowledge and understanding in a systematic manner using fuzzy logic concepts. Building on recent large-scale coastal investigations and with reference to a case study of the UK East Anglian coast, the fuzzy logic-based methodology defines the active coastal system using a flexible generic classification that integrates expert opinion as a basis for the assessment of potential future geomorphological response to changes in sea level and sediment supply. Preliminary results for the East Anglian coast suggest that shoreline management is already having, and will continue to be, a significant influence on coastal evolution irrespective of sea-level rise.

Morphodynamics of tidal wetlands

Status: ongoing

CERU has a long history of involvement in tidal wetlands research, with a particular focus on physical processes in saltmarshes. A recent paper in Marine Geology (French, 2006) re-interprets global data relating to vertical marsh growth and sea-level rise in the context of the conceptual model relating elevation, sedimentation, sea-level rise, sediment supply and tidal range. This analysis is supported by numerical mass balance modelling of the equivalent parameter space, and of the sensitivity of marsh hydroperiod and sedimentation to sea-level and sediment supply forcing. The effect of autocompaction on the translation of sedimentation into elevation change is also considered.

marsh_param_space.jpgParameter space modelling shows that sediment supply, and the efficiency with which this is depleted by deposition, exerts a strong control on marsh resilience to external forcing. Model results also indicate significant variability in marsh sedimentation associated with 18.6 year tidal modulation and meteorological processes at short-term scales: this complicates the interpretation of sedimentation or elevation change obtained from monitoring programmes of short duration.

CERU has long-term monitoring in place on saltmarshes in Norfolk (Scolt Head Island), Suffolk (Blyth estuary), and Essex (Blackwater estuary). This is based on the SET methodology in collaboration with the US Geological Survey and the University of Cambridge.
