Dynamics of a local Alpine flooding event in October 2011: moisture source and large‐scale circulation

2014

Alpine heavy precipitation events often affect small catchments, although the circulation pattern leading to the event extends over the entire North Atlantic. The various scale interactions involved are particularly challenging for the numerical weather prediction of such events. Unlike previous studies focusing on the southern Alps, here a comprehensive study of a heavy precipitation event in the northern Alps in October 2011 is presented with particular focus on the role of the large-scale circulation in the North Atlantic/European region. During the event exceptionally high amounts of total precipitable water occurred in and north of the Alps. This moisture was initially transported alon…

Competition of coagulation sink and source rate: New particle formation in the Pearl River Delta of China

2010

The coagulation sink and its role in new particle formation are investigated based on data obtained during the PRIDE-PRD2004 campaign at Xinken of Pearl River Delta, China. Analysis of size distributions and mode contributions of the coagulation sink show that the observed higher load of accumulation mode particles impose a significant effect on the coagulation sink and result in higher coagulation sinks at Xinken despite of the lower total particle number compared with other areas. Hence it is concluded that the higher coagulation sink may depress the occurrence frequency of new particle formation events. The strategies targeting at controlling accumulation mode particles may have influenc…

Environmentally-conditioned human rights: a good idea?

2021

The emergence of the rights of nature is a clear response to the current environmental crisis. But such trend is not to walk alone: it is to be espoused to the many still remaining human rights issues, otherwise the power and credibility of both are at danger. This chapter focuses on one of the many possible points of encounter between the rights of nature and human rights. It explores how they may be combined within biocultural rights—the basket of rights of indigenous peoples and local communities necessary to maintain their role as ecosystem stewards—and tries to understand what the consequences of combining nature and human interests as their foundations may be. In particula…

Storage and release of fossil organic carbon related to weathering of sedimentary rocks

2007

International audience; The biogeochemical carbon cycle, which plays an undeniable role in global climate change, is defined both by the size of carbon reservoirs (such as the atmosphere, biomass, soil and bedrock) and the exchange between them of various mineral and organic carbon forms. Among these carbon forms, fossil organic carbon (FOC) (i.e., the ancient organic matter stored in sedimentary rocks) is widely observed in modern environments but is not included in the supergene carbon budget. Using a digitized map of the world and an existing model of CO2 consumption associated with rock weathering, we establish the global distribution of FOC stored in the first meter of sedimentary rock…

Comparing modified biological monitoring working party score system and several biological indices based on macroinvertebrates for water-quality asse…

2005

Abstract Macroinvertebrate communities from the lower Nysa Klodzka River catchment, southern Poland, were analyzed seasonally, in order to assess changes in their composition and structure, in relation to water quality. Two major groups of sites, differing in both morphological structure and taxonomical composition by cluster analysis, were identified within the catchment area. Wider and deeper sites, located along the Nysa Klodzka River, were associated with the dominance of Chironomidae. Sites assigned along tributaries were characterized by a diversified structure of dominant taxa, including Oligochaeta, Hirudinea, Crustacea, Trichoptera, Ephemeroptera and Diptera. The performance of the…

El Guadalaviar y la configuración de Valencia : su interpretación a partir de las vistas urbanas modernas

2004

Pablo.Cisneros@uv.es Valencia responde a una configuración urbana creada por del río Turia o Guadalaviar. Esta relación es apreciable, claramente, en las numerosas imágenes urbanas que de esta ciudad se han conservado. Así, en el presente artículo se pretende realizar un estudio del río y de la ciudad a partir de las imágenes de Valencia en la Edad moderna. The Guadalaviar and configuration of Valencia. Its interpretation from the modern urban views. Valencia replies to an urban shape created by the Turia river or Guadalaviar. This relation is appreciable, clearly, in the numerous urban images which have been conserved in this city. Thus, in the present article pretends to carry out a study…

Morphological Similarity of Channels: From Linear Erosional Features (Rill, Gully) to Alpine Rivers

2017

The geometric characteristics of incised features such as channels, rills, ephemeral gully, gully, represent the erosional transport regime and the fluvial dynamic equilibrium, and thus it is critical for the understanding of the long-term evolution of natural, agricultural, and anthropogenic landscapes. This paper examines the morphological similarity of channelized erosion in two different environments such as Alpine landscapes and cultivated hillslopes. The first dataset comprises six rivers in the Italian Alps, three in the Carnia region and three in the Dolomites, where erosion is mainly the effect of discharges with high sediment loads or landslides and debris flows. The agricultural …

The flood of the Turia River of 1731. An approximation to the literature of the catastrophe

2015

Los sucesos naturales de carácter extraordinario que se han sucedido a lo largo de la historia han dejado tras de sí un gran legado documental. Fenómenos como los terremotos, las erupciones volcánicas, las sequías, las plagas, etc. han constituido desde siempre un motivo de preocupación para las poblaciones expuestas y una ocasión para desatar la imaginación de los cronistas. En el caso de la ciudad de Valencia, ningún fenómeno natural ha influido tanto en su historia como las avenidas recurrentes del río Turia. Una de ellas, la riada extraordinaria de septiembre de 1731, quedó registrada en documentos de todo tipo que pueden englobarse bajo la denominación común de literatura de la catástr…
