Potential of satellite based sensors for studying distribution of archaeological sites along palaeo channels: Harappan sites a case study

A large number of remote sensing based studies have shown evidence of a prominent river system, which has become buried under sand cover of Thar Desert sometime during late Holocene. This major river has been identified as Sarasvati, a legendary river mentioned in ancient Indian texts. This region is rich with archaeological sites of Harappan civilization (2500–500 BC). The present study has utilised digital image processing and enhancements techniques on multisensor satellite data followed by field investigations to reconfirm known traces and detect hitherto unknown traces of palaeochannels of Sarasvati river through parts of Indus alluvial plain in Thar desert. Potentials of IRS-P4 OCM (Primarily an Ocean Color Sensor, with eight narrow spectral channels, high radiometric resolution of 12 bits and large swath of 1420 m) could be exploited for the first time to detect hitherto unknown traces of palaeochannels of Sarasvati river through sand dune topography of Thar desert in parts of Western Rajasthan in India and adjoining parts of Pakistan by applying Principal Component Analysis technique. Pattern of palaochannels indicate westward migration of the Sarasvati river in parts of Indus alluvial plain. Database of more than 1000 archaeological sites compiled from various published sources, prepared in GIS environment could be utilised to understand their relationship with identified courses of the Sarasvati palaeochannels. Through this study it was found that there is a large spread of Mature Harappan (2200–1700 BC) sites along the palaeochannel of the Sarasvati and its tributaries in north-west India, but late Harappan (1700–1500 BC) sites are limited to further west in adjoining regions of Pakistan indicating that the shift of cluster of settlements have followed the pattern of river migration towards west. Digital terrain modelling by superimposing archaeological sites on SRTM DEM along with draped satellite data (Resourcesat-1 AWiFS and IRS-1D LISS-III) has helped in identifying geomorphological guides for archaeological investigations such as presence of relict natural levees seen as raised mounds and coincidence of known archaeological sites over them. It is suggested that other relict natural levees or raised mounds adjoining the identified palaochannel courses may be taken up for further archaeological exploration.     

The life cycle of bronze age metalwork from the Thames

The high proportion of Bronze Age metalwork found in the Thames has aroused interest for many years, but all too little is known of the circumstances in which this material was deposited. Much of it is weaponry, but there are finds of tools as well. This paper examines the material found upstream of Teddington and considers its treatment before it entered the river. A high proportion of the artefacts had been used and some of them deliberately destroyed. There are marked variations in the selection and treatment of these artefacts along different lengths of the river and in different periods of the Bronze Age, but it seems likely that the proportion of fine metalwork that was deliberately damaged before it entered the river increased sharply over time.     

黑水靺鞨思慕部探索

本文反对唐代“黑水”是指穆棱河与乌苏里江及其支流的观点,认为黑水是指黑龙江中下游段。结雅河下游发现的考古遗迹族属是黑水靺鞨之思慕部,不是从松花江迁移到结雅河下游流域的粟末靺鞨。靺鞨思慕部文化具有草原文化的成分。靺鞨族人种是复杂的、多源的。思慕部墓葬人骨得出的人种类型只能代表思慕部,能否代表黑水人种,或代表全体靺鞨人种,还需要新的对比材料。     

THE ACEHÚCHE GOLD TORC: GOLD AND SACRED LAND ON THE SHORES OF THE TAGUS RIVER (CÁCERES,WESTERN SPAIN)

This article describes the important discovery of a Late Bronze Age gold torc that was unearthed in a field of Acehúche (Cáceres, Spain). It was buried underneath some rocks at a site near a river crossing over the Tagus river. In its immediate vicinity, archaeological remains dating from the Copper Age to the Late Bronze Age have been found, which indicates the long use of this crossing. Until recently here, there existed a ferry and a chapel; and the place went by the toponym of the Dehesa de San Cristóbal. Legend too has it that the water from the river had curative properties. All of these components have maintained the sacred nature of the spot, otherwise transformed over the course of time, and reflect an earlier sacred landscape with quite ancient roots.     

Reflections on the historical origin of regions and pays

This paper examines the historical origin of two related but distinct types of country-side or pays in England: those based on early-settled river-valleys and those associated with areas of wold. W. G. Hoskins has pointed out that in Devon early places like Tawton and Taviton derived their names from rivers and were associated with outlying stocks or cattle-farms—Tawstock and Tavistock—which originally formed distinct but related parts of the same river-estate.A similar association is found in many areas. Two examples in Kent, where the evidence for early settlement is unusually abundant, are examined in detail: the estates of the Darenth people and the Bourne people. In both cases settlement pressed inland from the river itself, far up into the wooded Downland or wold. As well as their original river communities they thus developed an outlying area of summer pasture based on isolated forest shielings. The former may have originated before the English invasions and were certainly very early. The development of the shielings into permanent farms occurred later, mainly in the middle- or later-Saxon period.The Kentish evidence is significant for three reasons. First, there can be no doubt that in the county as a whole the wold region or Downland originated as the outlying summer pasture of the river-estates. Secondly, as the isolated shielings evolved into permanent farms, the region developed an independent life of its own, with distinct characteristics from those of the parental river-settlements. Thirdly, the word wold occurs widely in the Downland place-names of East Kent, where it definitely denotes woodland or forest, and not simply the “elevated stretch of open country” which it is often said to signify. Did other areas of wold, now largely woodless, such as the Cotswolds and Lincolnshire Wolds, also originate as the outlying wood-pasture of early river-peoples?

Space, Time and Sustainability in the Hadejia-Jama'are Wetlands and the Komodugu Yobe Basin, Nigeria

Debates about sustainability still take insufficient account of the significance of space and time. In this paper, their significance is demonstrated empirically through an account of the complex environmental and socio-economic impacts of dam construction on flood-plain wetlands in the Hadejia-Jama'are river basin in Nigeria. Socio-economic data from a rapid rural appraisal exercise and household questionnaire survey (data on patterns of production in the flood plain and patterns of mobility) are appraised in the context of patterns of environmental change and of inundation (analysis of riparian vegetation and time-series aerial photographs). The paper concludes that sustainable river basin development requires more attention to be paid to the perspectives derived from different scales of analysis. This calls for appropriate institutions allowing communication at the interface between village-level producer and river basin manager.     

Revisiting the Exploitable Threshold Model: 14th century resource procurement and landscape dynamics on Perry Mesa,Arizona

Abstract

This study presents a revision of Dean E. Arnold’s (1985, 1993) Exploitable Threshold Model, which attempts to explain the selection of raw materials for pottery production. Arnold’s model posits that potters’ preferences for materials are largely determined by the linear distance to individual resources. We argue, however, that potters’ choices are, at least in part, determined by spatial relationships among the necessary resources rather than the distances to them. This study of 14th century pottery production on Perry Mesa, Arizona demonstrates that potters selected materials based on the co-occurrence of readily available sources of temper, clay, and fuel. Lack of water and fuel sources on the mesa top compelled local residents to eschew the use of readily available basaltic sands to temper their plainware pottery. Instead, Perry Mesa potters selected granitic sands from the river valley nearly 300 vertical meters below their settlements.     

The Geography of the Anthropocene in New Zealand: Differential River Catchment Response to Human Impact

New Zealand provides a useful environment to test the notion that the Anthropocene is a new geological epoch. There are two well‐dated anthropogenic impact ‘events’: Polynesian settlement c. AD 1280, and European colonisation c. AD 1800. Little attention, however, has been given to regional catchment response to these, although it has been assumed that both Polynesian and European farming and land use management practices significantly increased erosion rates across most of New Zealand. This paper addresses the nature and timing of human impacts on river systems using meta‐analysis of a recently compiled nationwide database of radiocarbon‐dated fluvial deposits. This shows highly variable human impacts on erosion and sedimentation in river systems, which are often difficult to separate from naturally driven river activity. Catchment‐scale data with high resolution dating control record clearer evidence of human disturbance. In Northland, anthropogenic alluviation is recorded from c. AD 1300 linked to early Polynesian settlement, enhanced further in the late 19th and 20th centuries by European land clearance, when sedimentation rates exceeded 25 mm year^?1. This study demonstrates significant geographical variability in the timing of human impact on river dynamics in New Zealand, despite two synchronous phases of human settlement, and highlights the difficulty of formally designating a simple and single ‘Anthropocene Epoch/Age’.     

历史上永定河筑堤的环境效应初探

金、元以后永定河水害急剧增多,由北京的母亲河变成了常常威胁京城安全的害河。金代以来各朝都十分重视对永定河的治理,元明清三朝更是把修筑永定河的堤防作为京畿事务中的重大问题。历史上永定河的大规模筑堤为京城减少了洪水之虞,但同时也带来了包括北京水环境在内的一系列地理环境的变化。本文追溯永定河筑堤后北京地区水环境变迁以及下游地貌改变的重要史实,阐述筑堤工程对于流域整体环境的深远影响,以期引起人们对历史上一些重大水利工程的环境效应的反思。     

River landscapes: The origin and development of the printed river map in the Netherlands, 1725–1795

Abstract

River management in the province of Holland in the eighteenth century was co‐ordinated by a Hydraulic Department which worked closely with local, regional and other provincial authorities to maintain river beds and channels. To perform its function efficiently, all the Hydraulic Department's main river maps followed general precepts laid down as early as 1725 by the surveyor Nicolaas Cruquius (1678–1754). The basic principle was to create clear maps with uniform scale and design which contained only the topographical information relevant to the work of the department. Experiments with depth contours were made, and profiles and diagrams were included in order to portray as accurately as possible the invisible natural processes which influenced the river landscape. The cartographical model thus established was followed consistently throughout the eighteenth century.     

Archaeological sedimentology of overbank silt deposits on the floodplain of the Ohio river near Louisville,Kentucky

The surface of the floodplain of the Ohio River about 20km southwest of Louisville, Kentucky, is a series of linear ridges and swales that are subparallel to the channel of the river, which here is relatively straight and flows southward. Numerous prehistoric occupational sites are located on these ridges. The sediments that underlie the ridges, which were examined in four archaeological excavations as deep as 8 m, are predominantly sandy silt and silty fine to very fine sand and appear to be mainly the product of overbank deposition from suspended load. Abundant cultural material and occupational sites dating as early as 10,000 years BP are found in the sediments at depths as great as 6·5 m. The fine sediments of the floodplain are underlain by sand and gravel.The context of the cultural materials and the stratigraphy and morphology of the deposits indicate that the ridged deposits began as linear riverside sand and gravel bars. These were succeeded upward by fine-grained overbank deposits in which the ridged morphology was maintained because the overbank silt and fine sand were deposited as prograding elongate bars at high water. As the floodplain ridge built upward, the sedimentation rate decreased and the sand content of the sediments diminished, and as the river channel occasionally shifted, the ridged deposits were built in successive subparallel sequences.Two archaeological consequences are implicit in this depositional model of orderly growth of the floodplain. First, available archaeological data from floodplain segments along other parts of the river should confirm the model; and second, the model should make it possible to search the floodplains of the Ohio River for stratified sites of any desired age.     

A Study of the Sewn‐Plank Boats of Goa,India

The study of traditional boats has enhanced our knowledge of the maritime past. Traditional boats are both river‐ and sea‐worthy. They have been used in rivers for transporting cargo to inland ports from ships anchored at sea, and have often been used in naval warfare. In this paper an attempt has been made to study the sewn‐plank boats of Goa, their building techniques and other features in order to understand their quality and how they were used in the past for an inland river‐transport system. © 2011 The Authors     

明清时期潇河河道迁徙原因分析

潇河是汾河的第二大支流,其流域是晋中重要的经济区域,明清时期流域水患灾害渐重,其中下游河道频繁迁徙是新出现的灾害。由于流域较小,正史记载不详,本文以地方志为主要材料探究了河道迁徙的主要原因。鉴于历史时期该流域植被一直较少,明清上游白马河一带又未出现较大规模的山地坡垦,故河道迁徙之根源应在下游。本文认为其主要原因有二:首先,流域洪涝暴雨是河道迁徙的直接诱因;其次,下游湖泊消失、渠道密集等生态环境之变化则是根本原因。

Age and sedimentological features of fluvial series in the Toruń Basin and the Drwęca Valley (Poland)

The deposits of the Toruń Basin are dominated by a few-metre thick sand series which fill up buried valley-like depressions. In many cases they underlie the Weichselian till which builds up the ice marginal streamway (pradolina) terraces or they are exposed at the basin slopes. As the results of the geological and sedimentological studies, as well as of the dating of the deposits at the sites in the Toruń Basin indicate, the deposits include two fluvial series accumulated before the advancement of the Leszno Phase ice sheet, i.e. in Middle Weichselian and at the beginning of Late Weichselian. The oldest fluvial series connected with the Saalian Glaciation was found at the mouth section of the Drwęca Valley. The fluvial system of the Toruń Basin during Middle Weichselian and at the beginning of Late Weichselian developed in two phases of the sand-bed braided river. During the first one the river channel were dominated by large mid-riverbed sandbars, while during the second phase the water flow was smaller and, as a result, low transverse sandbars and two-dimensional dunes developed. Other active river channel also showed low-energy flows, more intensive meandering than in the case of the braided rivers, as well as sandy side-bars. Analysis of the rounding and frosting of the quartz grains indicate that the studied series of the Weichselian sandy deposits represent alluvia of a river which were fed from two diverse sources. The first one might have represented the alluvia of a warm river which transformed its load, while the other one might have mainly carried the underlying Quaternary deposits.     

Layering,Administrative Change and National Paths to Europeanization: The Case of the Water Framework Directive

The EU Water Framework Directive (WFD) can be seen as a reform effort that intervenes in the member states' domestic administrative system by obliging “whole of government” measures across sectoral lines of authority and levels of government. This puts pressure on the sectoral authorities to coordinate their activities. In this article we ask the following questions: How do the state executives respond to the WFD? How can we understand their behaviour and action choices in the implementation of EU law? And third: What can our findings tell us about changes to the European administrative system? This article reveals that despite resistance and strong cognitive priors among the state executives, the WFD logic of ecosystem-based management is gaining a foothold as an administrative principle. Thus, in order to explain changes in the administrative system, we need to take the regional level into account. Our findings suggest that attention needs to be paid to the role of complex, multi-level structures, which includes the regional, river basin district level in the development of a European administrative order.
