Rivers of dreams: on the gulf between theoretical and practical aspects of an upland river restoration 总被引:2,自引:0,他引:2

This paper is concerned with development and application of a conceptual model of the river restoration process and, through a specific case study, a demonstration of the challenges that arise when combining ecological and geomorphological principles with social and economic issues. Thus, it demonstrates the difference between the ideal goals of river restoration and the practical determinants of the nature of a river restoration that derive from individual and community goals. It begins by exploring theoretically what a river restoration project might involve. It then introduces the options developed for restoration of a particular case study river and the associated decisionmaking process. As a result of strong community involvement, institutional and financial regulations, the location of the restoration site in a National Park, and the influence of governmental and non-governmental organizations, the actual decisionmaking process resulted in a practical river restoration that departed significantly from the idealized goals of a restoration defined in purely scientific terms. It is argued that these practical limitations are likely to remain the dominant influence upon the nature and scope of river restoration projects. 相似文献

Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) data are used to explore the structure of obsidian acquisition for groups in the King Range National Conservation Area of northern California. The data indicate that, contrary to a distance-decay model, obsidian from more distant sources in the Medicine Lake Highlands, dominates the obsidian found at sites in the area. Furthermore, metric data indicate a positive relationship between size and distance to source with more distant sources represented by larger flakes. It is suggested that this pattern is the result of culturally mediated exchange relations under which Athabaskan speakers concentrated trade relations with one another to the exclusion of trade with linguistic groups to the south, with longer histories in the area, such as the Pomo and Yuki. Additionally, the use of redwood dugouts on rivers in northern California and the importance of northeastern Californian obsidian in ritual practices of California Athabaskan groups may have further encouraged the use of more distant, northeastern Californian, sources. 相似文献

Morphological characters for the separation of red and fallow deer remains are described. These encompass antlers, permanent dentition, and postcranial bones. The characters were tested on samples of known red and fallow deer from an array of contexts, thus helping to ensure their validity across different populations. An attempt is made to quantify the reliability of each character, using a simple arithmetic method of scoring and analysing the test data. This forms the basis for a more objective assessment of the identity of an unknown specimen. 相似文献

The political ritual generated by Japanese whaling in the Southern Ocean annually captures the Australian imagination and at least the attention of international audiences. This article examines how Australia has become the self‐appointed guardian of Antarctic whales whilst Japan remains resolutely pro‐whaling. 相似文献

The papers in this special issue exemplify how, through the study of sources beyond the chronicles which have tended to dominate historical writing about fourteenth-century military history in western Europe, we can advance our knowledge on how war was waged by the English — and on some occasions by their enemies too. 相似文献
