Hydrogeological Modelling of Water-Level Changes in an Area of Archaeological Significance: A Case Study from Flag Fen,Cambridgeshire, UK

Concern exists regarding the long-term viability of the internationally important archaeological remains of the Flag Fen site near Peterborough. This paper describes a hydrogeological numerical groundwater model which has been used to understand the groundwater situation with regard to the archaeology, including drainage impacts, and also to explore future scenarios. Observed and modelled groundwater levels have been interpreted using three zones: the ‘dry’ zone 1 above the seasonal maximum water table; zone 2 of seasonal water table fluctuation; and a deeper zone 3 of permanent saturation. Archaeological wood is best preserved in Zone 3. Much of the Bronze Age wooden structure is located within Zone 2 or above. The hydrological conditions are therefore not ideal for the long-term in situ preservation of the material. Groundwater modelling indicates that the main factor controlling groundwater levels in the area is artificial drainage. The approach would be applicable to other wet-preserved archaeological sites.     

A Farewell to Alms: A Brief Economic History of the World

Abstract

The reasons for the lack of communication between economists and econophysicists are clarified by giving an outline of the methodological differences between economics and econophysics, which has emerged as a new field of research over the last decade. Theorists working in econophysics see economic and financial phenomena through the ‘lens’ of statistical physics. So far, there has been no real dialogue between economists and econophysicists because both communities adhere to their own methodological precepts.     

“Fixing” Climate Change by Mortgaging the Future: Negative Emissions,Spatiotemporal Fixes,and the Political Economy of Delay

Models suggest that climate change mitigation now depends on negative emissions, i.e. the large‐scale removal of carbon dioxide from the atmosphere. This assumption has been criticised in the climate policy literature for being unfeasible and unjust. This article asks how critical scholars can make sense of, and contribute to these debates. It suggests that negative emissions can be conceived of as a spatiotemporal fix that promises to defer the devaluation of fixed capital. But the negative emissions example also challenges us to broaden our conception of how the socioecological contradictions of capitalism can be “fixed”. I outline three ways in which it does this by highlighting the significance of a predominantly temporal fix, the role of hegemonic, sociopolitical interventions involving multiple actors, and the possibility of safeguarding existing production processes. I conclude that spatiotemporal fixes to climate change should be seen as part of a wider political economy of delay in devaluing carbon‐intensive accumulation processes.     

A simple methodology for recording petroglyphs using low-cost digital image correlation photogrammetry and consumer-grade digital cameras

In the present study a simple method is described for obtaining 3D digital models of petroglyphs of different sizes and characteristics and its usefulness, in the study of this cultural heritage, is evaluated. For this research we used low-cost photogrammetric software and consumer-grade digital cameras, without any other surveying techniques. In order to test this methodology, three field research studies were carried out in Galicia (Spain).     

An ethnoarchaeological inductive model for predicting archaeological site location: A case-study of pastoral settlement patterns in the Val di Fiemme and Val di Sole (Trentino,Italian Alps)

In this paper I propose a novel integration of inductive predictive modelling and ethnoarchaeology. The case study concerns seasonal upland pastoral settlement patterns in the eastern Italian Alps. A sample of modern pastoral sites has been selected, and their relationships with environmental variables have been analyzed in order to create a model to predict the location of archaeological upland pastoral sites. The model has been tested with modern and archaeological control samples. It has proved to be useful for predicting the location of specific site categories. Ethnoarchaeological fieldwork has been carried out in the same alpine sample area, which has enhanced the interpretative potential of the proposed model, suggesting that the spatial of the analyzed sites could well be related to their dairying function. The creation of ethnoarchaeological locational models with a predictive potential may be very important not only in helping to tackle some theoretical and methodological problems in predictive modelling, but also in enhancing the importance of ethnoarchaeology in landscape archaeology projects.     

Modelling small-arms projectile distribution on eighteenth- and nineteenth-century battlefield sites

The application of Geographic Information Systems (GIS) technologies to archaeological investigations continues to provide new perspectives on historical events. Applied to battlefield archaeology, GIS analysis offers an efficient means of predicting potential artefact distribution across a conflict landscape. The approach proposed in this piece allows a user to test historical engagement scenarios within a desktop computing environment utilizing a customized GIS application. The study was intended to develop a framework that allowed for the input of quantifiable parameters in order to illustrate potential artefact patterning. The framework consists of two components, the trajectory model and the methodology for implementing it. Using this coarse-grained approach, it is our contention that small-arms projectile distribution can be estimated for a single engagement, and in doing so provide a more comprehensive view of potential artefact patterning than using KOCOA (Key Terrain, Observation and Fields of Fire, Concealment and Cover, Obstacles, Avenues of Approach/Withdrawal) terrain analysis or historic research alone. As an initial example to illustrate the efficacy of our model, this study uses data and parameters from the 1777 Battle of Ridgefield, Connecticut landscape as a test case.     

MODELLING OF THE GROUND MOTION AT RUSSE SITE (NE BULGARIA) DUE TO THE VRANCEA EARTHQUAKES

An approach, capable of synthesising strong ground motion from a basic understanding of fault mechanism and of seismic wave propagation in the Earth, is applied to model the seismic input at a set of 25 sites along a chosen profile at Russe, NE Bulgaria, due to two intermediate-depth Vrancea events (August 30, 1986, M _ω=7.2, and May 30, 1990, M _ω=6.9). Accordingly to our results, once a strong ground motion parameter has been selected to characterise the ground motion, it is necessary to investigate the relationships between its values and the features of the earthquake source, the path to the site and the nature of the site. Therefore, a proper seismic hazard assessment requires an appro-priate parametric study to define the different ground shaking scenarios corresponding to the relevant seismogenic zones affecting the given site. Site response assessment is provided simultaneously in frequency and space domains, and thus the applied procedure differs from the traditional engineering approach that discusses the site as a single point. The applied procedure can be efficiently used to estimate the ground motion for different purposes like microzonation, urban planning, retrofitting or insurance of the built environment.     

MODIFICATION OF SITE RESPONSE IN PRESENCE OF LOCALISED SOFT LAYER

Experimental and numerical simulations are performed to evaluate the modification of ground response resulting from either the presence of soft layers or occurrence of partial liquefaction. Results from two densely instrumented dynamic centrifuge tests are presented to show the ambiguous role played by the presence of a soft layer. It was found that the lateral extent of the soft layer has significant influence on the overall response of the layered strata and any structure founded on it. The experimental observations are supported by simplified numerical analysis. The amplification or deamplification of the input motion is found to be a function of the ratio of the width of soft layer to the wave length. Based on the numerical analysis, a general function describing the site amplification is presented which may be used as a guide in seismic design of foundations in such layered strata.     

The Newport Medieval Ship,Wales, United Kingdom

The Newport Ship is the most substantial late medieval vessel excavated and recovered in Britain in recent years. It was abandoned after extensive salvage, possibly following attempts at repairs to the hull. More than 23 m of the clinker‐built ship were recovered, along with significant artefact and environmental assemblages. Finds point to strong Iberian connections during the active life of the ship, which arrived in Newport in the Severn Estuary, after the spring of AD 1468. The dismantling and recovery of the ship has enabled detailed recording using innovative 3D digital techniques and approaches to hypothetical reconstruction. Publication includes a digital archive hosted by the Archaeological Data Service, a substantial report and this article.     

Integrated Design of Conservation of the Archaeological Heritage

Abstract

This article aims to establish a connection between (a) the identification of heritage and measures for its protection, and (b) the collection and dissemination of scientific information, as set out in the Treaty of Valletta. This is illustrated through research conducted at the Asklepieion of Kos, which led to an anastylosis project on the Roman temple, within a wider project to re-organize the entire area of the sanctuary. The paper highlights the development of the project, including traditional methods of direct survey (manual and digital), a database of the three-dimension models of the single architectural elements of the temple, and a CAD/CAM model of the reconstruction project.
