Recent trends in rivers with near-natural flow regime : The case of the river headwaters in Spain
The aim of this research was to study the streamflow evolution of a representative sample of the Spanish near-natural-regime fluvial system over the last 4 decades of the 20th century. A representative sample of 74 rivers was selected
and a statistical analysis was performed to detect seasonal and annual trends, and the magnitude of streamflow change. Almost all of the rivers studied experienced reductions in streamflow. The main decreases in the discharge of these near-natural rivers in Spain
Quantifying effects of deep and near-surface chemical erosion on cosmogenic nuclides in soils, saprolite, and sediment
The AA. quantify the extent to which overlooking effects of chemical erosion introduces bias in interpreting denudation rates from cosmogenic nuclides. They consider two end-member effects : one due to weathering near the surface and the other due
to weathering at depth. If this effect is ignored, denudation rates inferred from cosmogenic nuclides will be too low. The AA. derive a general expression, termed the chemical erosion factor, or CEF, which corrects for biases introduced by both deep and near
Mass balance and near-surface ice temperature structure of Baishui Glacier No.1 in Mt. Yulong
Based on the field observations of mass balance and glacier temperature at Baishui Glacier No.1 in Mt. Yulong, its accumulation, ablation, net balance and near-surface ice temperature structure were analyzed and studied in this paper. Results showed
Topoclimatological case-study of Alpine pastures near the Albula Pass in the eastern Swiss Alps
climate of Alp Weissenstein. Mountain top stations, however, did not provide a convincing approximation for the climate at Alp Weissenstein. Direct comparisons of near-surface measurements from a set of 11 small weather stations distributed over the domain
was located near Nizzana, in the northwestern Negev, Israel and the temperate site was near Lieberose, Brandenburg, Germany. BSCs were sampled at each site near the dune crest, at the center of the dune slope and at the dune base. The soil texture was finer
The goal of this study was to map active-layer thickness (ALT) and the presence or absence of near-surface permafrost at 30-m resolution throughout the Yukon Flats Ecoregion (YFE) of central Alaska. The AA. 1) compiled airborne electromagnetic (AEM
and spectral characteristics; 3) spatially modelled near-surface resistivity (NSR) across the YFE at 30-m resolution using piecewise regression; and 4) spatially modelled ALT and near-surface permafrost from field data, predicted resistivity, and satellite
An arid watershed at the Walnut Gulch Experimental Watershed (WGEW) near Tombstone, AZ, was instrumented with both systems and hydrologic and sediment data were collected and compared during a 2 year period. Total sediment yield for the entire
The USLE scheme cannot be used at the Sparacia experimental area (near Palermo,Sicily) to predict event soil loss per unit plot area, Ae, because experimental data suggest that, generally, Ae does not increase with plot length, λ. The USLE-MM scheme
velocity profiles. Reynolds stresses in the streamwise (u) and vertical (v) components of the flow show positive values near the channel bed and negative values near the ice cover, with 2 distinctive boundary layers with specific turbulent signatures
that rocks near the limits of altitudinal zones are dated with much more serious errors than is the case for those in the central part of an altitudinal zone. This paper therefore discusses a new lichenometric curve defining thallus growth directly
This paper uses Jacques Rancière's conception of the partition of the sensible to interrogate the aesthetic regimes and spatial coordinates that animated public debate about Park 51—the Islamic community center near the World Trade Center site
This paper addresses the pursuit of environmental sustainability by an autocratic, neo-patrimonial regime and examines the implications of such a political environment for sustainable initiatives in Masdar City , near Abu Dhabi. The findings reveal
mining between the 1950s and 1980s and it started to increase after the decrease of mining activity. The paper is about the mineral contents and geomorphic properties of karst water springs near a chosen reservoir and authors’ aim was to get some
mapping concept and to develop an analogue database to the “manually” created, existing SOTER databases. A simplified soil parent material classification was developed and tested for remote sensing based application. Multitemporal, visible, near infrared
is satisfactory, but there are considerable differences in the speed of the rehabilitation process, which may result in a deepening polarisation of the quality of life on the estates in the near future. - (AM)
