Excavations revealed important elements of a pre-Flavian fort, including a well-preserved clay and turf rampart, barrack blocks and a granary. A good assemblage of contemporary pottery, metalwork and glass was associated with these levels. The results are assessed with a discussion of previous excavations in Abergavenny. The site also yielded the first firm evidence of the town's Norman defensive bank and later Edwardian town wall. A Civil War phase of defences was also recorded.  相似文献

The growth of the study of English artillery fortification, coupled with the various inadequacies of B. H. St J. O'Neil's Castles and Cannon, mean that a reappraisal of the development of these defences is long overdue. The scattered evidence, both architectural and documentary, for pre–1539 works is brought together to form a background against which studies of individual sites may be made. The emphasis is on castles, town defences and blockhouses, but there is a separate section relating to fortified manor-houses. The major fortifications are studied in three sections, each reflecting a stage in the development of artillery fortification. The effectiveness of the defences is assessed based on surviving buildings as well as the capabilities of early ordnance, on which there is a section. 1539 is the terminal date for the study, for in that year Henry VIII's coastal forts marked the end of the basically medieval ideas that went into the planning of the first forts.  相似文献

Abstract

The eighteen month occupation of Haddington 1548–1549 is said to be Scotland's longest siege. French, German and Scottish armies battered the defences of the burgh town trying to dislodge a stubborn and forlorn English garrison. In September 1549, the English relief column arrived unopposed and extricated the remaining plague-ridden defenders, leaving the fortifications to be levelled by the besiegers. The fortifications at Haddington were the first appearance in Scotland of the Trace Italienne, designed to defeat conventional siege tactics; bombardment, sapping and storming. Despite long-held assumptions that the fortifications are now lost to history, recent research indicates the survival of elements of the defences.  相似文献

The dramatic decline in the integrity of Australian river systems in recent decades has seen the development of landcare and catchment management groups across the continent as the main facilitators of river rehabilitation works. There is growing concern for the need to develop adaptive management frameworks that assist informed decision making through the integration of social and geomorphological knowledge into catchment planning. In the Mulgrave River Catchment of northeastern Queensland, difficult management decisions have to be made with limited access to knowledge of natural processes and baseline geomorphological data. To date management decisions have been based almost exclusively on oral histories that state that point bars are accreting and the river is becoming shallower due to bank erosion. As a result bank stabilisation and removal of sand from within the channel have been recommended in the absence of any geomorphological assessments. This study compares oral histories of river bank erosion in the Mulgrave River with geomorphic evidence to highlight the need for integrated landscape scenario planning. The results of grain size analysis of bank and bed material from 27 locations, involving 47 samples, suggest that bank erosion cannot be delivering sediments to point bars. Furthermore, qualitative analysis of historic parish maps and aerial photographs shows that there has only been moderate bank erosion at three locations along the Mulgrave River since European settlement. The study demonstrates the important role that geomorphological investigations have for catchment management and the need for management frameworks that integrate geomorphological processes and landholder priorities for sustainable river management.  相似文献

清中叶以降,清宫档三汛(桃花汛、伏汛、秋汛)安澜奏本中所见荆江洪水位开始日益上涨,咸丰、同治年间,藕池、松滋决口向洞庭湖分流后,水势稍有缓解,至光绪年间复又急速抬升。不断上涨的洪水位对江北入江河流造成了两方面影响: 其一为河道的变迁,其二为水环境的变化。在沮漳河流域,涉及长江百里洲的变迁,沮漳河入江口的变动,长江主泓迁移,下百里洲靠岸及洲尾东摆引发沮漳河下游延长,以及山水、江水相互顶托造成水环境淤积。在玛瑙河流域,则表现为荆江洪水位抬升对河水的顶托现象,导致入江尾闾沼泽化。  相似文献

This article explores the consequences of a massacre of civilians in Asaba, a town on the west bank of the river Niger, during the early stages of the Nigerian civil war. While ethnically Igbo, Asaba was not part of the Igbo-dominated Biafra, remaining part of the ethnically diverse midwest region. In the international memory of the war, the midwest action, which claimed several thousand lives, has been eclipsed by the catastrophic events east of the Niger, after the federal blockade of Biafra. This article sheds new light on the human cost of the war on civilian populations outside Biafra. Drawing on interviews with survivors and their descendants, we describe the killings, pillaging and rapes that followed the arrival of the federal troops, and trace the long-term impact and memory of the physical and human devastation in Asaba on family structure, gender roles, educational opportunities and social structure. We show how the official suppression of the massacres, coupled with Biafran awareness of the events, contributed to the subsequent course of the war, and we suggest that this suppression has left a legacy that perpetuates resentment and has kept ethnic tensions alive to this day.  相似文献

Town walls have always played a critical role in shaping the identities and images of the communities they embrace. Today, the surviving fabric of urban defences is a feature of heritage holding great potential as a cultural resource but in management terms one that poses substantial challenges, both practical and philosophical. Town walls can be conceptualised as a ‘dissonant’ form of heritage whose value is contested between different interest groups and whose meanings are not static but can be rewritten. Evidence is gathered from walled towns across Europe, including member towns of the WTFC (Walled Towns Friendship Circle) and inscribed UNESCO World Heritage Sites, to explore the cyclical biographies of town walls in their transformation from civic monuments, through phases of neglect, decay and destruction to their current status as cherished cultural resources. To explore this area of interface between archaeology and tourism studies, the varying attitudes of populations and heritage agencies to walled heritage are reviewed through examination of policies of conservation, preservation, presentation and restoration. Areas of commonality and contrast are thus identified.  相似文献

元代的吴淞江治理及干流“改道”问题   总被引:2,自引:1,他引:1  
曾为太湖的主要泄水入海通道的今黄浦江支流吴淞江 ,当有元一代 ,曾经进行过规模相当、持续不断的“治理”。通过对相关资料的重新考察 ,得出以下结论 :一、由于时人的“肆意妄为”,入元以后的十数年间 ,原本“安流”的吴淞江水系遭到了严重的破坏 ,从而开始了难以“恢复”的不可逆转。二、至元末的淀山湖工程、大德末的吴淞江工程以及泰定、至顺、至正中的工程 ,都不是“有效”的水利工程 ,究其原因 ,一是没有从整体的利害关系考虑 ,二是有违当时已经形成的“自然”态势 ,那就是太湖水流宣氵曳日益向南的“必然”演化。三、关于南宋吴淞江的干流 ,并不如许多研究者所言即明代的“虬江”、今天的西虬江。准确的表述应是 :当时的吴淞江河床包含今吴淞江南岸到虬江北岸间的整个区域。“虬江”亦是“旧江”,不过是由于河床垫高、水流分岔后的一股北去水道的遗迹而已  相似文献

RUMNEY CASTLE, a small ringwork historically part of the marcher lordship of Gwynll?g, was situated above a steep natural scarp overlooking the R. Rhymney. First mentioned in A.D. 1184–85, the castle guarded the W. boundary of the lordship and the river crossing. The defences consisted of a ditch and clay rampart constructed around three sides of the site. Initially incorporated into the defences along the fourth side was a large timber building and possibly a palisade. The entrance was originally defended by a large timber gate tower, later superseded by a smaller timber structure. Following this, the defences were strengthened with the widening of the rampart and the construction of a small tower or keep alongside the entrance. Several phases of timber building, including two large halls, were arranged around a courtyard. During a later period the entrance was relocated and a stone gate tower constructed.

During the second half of the 13th century the site was converted for use as a manorial centre. The rampart was levelled, the interior of the site infilled, and a range of buildings constructed along the edges of the mound. A well-sealed coin hoard of c. A.D. 1288–89 discovered in a destruction deposit provides a terminus post quem for the abandonment of the site.  相似文献

Since 1955 the NSW Department of Water Resources has undertaken extensive river training works on many NSW streams. In the Hunter Valley alone over $23 million have been spent and more than 850 km of channel have been treated Published work suggests that river training works are usually undertaken in response to a pre-existing problem of river instability but can also induce adverse hydrogeomorphic effects. One of the treated streams, the Allyn River, had been supposedly degraded by the constructed works. It was alleged that vegetation clearing, channel excavations, alignment straightening and bank protection works had decreased roughness thus increasing velocity and flood frequency. As a result, what were thought to be relatively moderate floods were eroding the banks and destroying the floodplain. A critical evaluation of the available hydraulic, hydrologic and geomorphic data revealed that the river training works were a response to, rather than a cause of river instability.  相似文献
