Geomorphic consequences of urban development and mining activities; an analysis of study areas in Spain and Argentina
The analysis has been carried out in 4 study areas : a basin in northern Spain and 3 municipalities in central Argentina. The AA. consider direct effects of excavation, transport and accumulation of materials as well as unintended effects related
Rates of sediment supply by landsliding to an alluvial channel in a small catchment in central Switzerland were estimated over an 11-month study period. Fluvial sediment transport in the channel is independently monitored at the upstream
and downstream ends of the study reach, yielding a unique opportunity to quantitatively compare the volume of sediment supplied to the channel with the volume in fluvial transport, and their net effect on the channel, over a period of 11 months. The AA. also
compare changes in channel bed elevation over the past 11 years to examine whether the seasonal-scale behavior is consistent with decadal-scale aggradation in the study reach.
Considering its small territorial and population size, Slovenia nevertheless has a considerable geographic, economic and social variety. Not surprisingly, there are significant regional disparities. A resarch study analysed statistical data
for the chosen indicators in the periods 1961-1991 and 1991-2002 and evaluated the demographic potential in the four demographically endangered and economically less-developed areas. The study has also examined in detail eight settlements at selected areas
. A special emphasis was placed on the study of households as basis socio-economic units, on which future development of settlements is based. - (BJ)
The main aim of this study is to examine the change in extent of degraded areas and gully systems over time using data from 5 sets of aerial photographs. Data on the extent of crop cultivation is assessed as a possible ancillary causal factor
for the observed degraded features. Reasons for changes are suggested in the light of available climatic and land use data for the study area. Data from erosion pins and sedimentation in 2 dams located in the study area are used to give a third dimension to the two
The impact of land use on soil properties in a karst agricultural region of Southwest China : a case study of Xiaojiang watershed, Yunnan
In this study the AA. analyzed the land use changes from 1982 to 2003, and assessed the effects of land use changes on pH value, organic matter, total N, total P, total K, available N, available P and available K in soil of Xiaojiang watershed
and global positioning system) to assess the severity of land degradation risk. The northern part of Shaanxi province in China was taken as a case study. Satellite images of the study were acquired in October 1987 and in October 1999 (Landsat TM images). All
5 thematic layers were generated in GIS environment at a scale of 1:250 000. The software used for this study was Arc/Info and ERmapper imagine.
of different sizes of bedform; the aims were to : study whether bedforms heights have any role in grain-size distribution patterns, offer a best-fit statistical model, study the downstream variation of size-sorting in a point bar system, and study the mechanism
This paper discusses direct current resistivity soundings and geomorphological studies of Quaternary deposits in 2 glacial throughs in the Abisko Mountains of northern Sweden. The subject of the fieldwork is the depth of Pleistocene glacial erosion
. Studies were carried out in 1998 and 2003 in the Kärkevagge and Vassivagge. The estimated thickness of Quaternary deposits and bedrock properties are discussed in the broader context of glacial erosion studies in the Abisko area.
Settlement history as reflection of climate change : the case study of Lake Jues (Harz Mountains, Germany)
. Climate variability was mainly inferred from sediment characteristics and changes in algal assemblages. The observed climatic changes coincide well with those recorded from other sites. The study shows that climate strongly influenced human settlement
The article presents how our view has changed on the significance of mass movements over the last fifty years since the publishing of the most important studies by Béla Bulla. The study based on international databases provides a picture
The aim of this study is to develop a methodology that allows for an estimate of the hydroclimatic influence on an inland pond system on San Salvador, Bahamas. The methodology utilizes the Hydrologic Landscape Unit (HLU) model, a new conceptual
model. For this case study, a linear regression model was developed to empirically assess the HLU. This analysis separates tidal and climatic impacts on water levels of the pond and indicates that astronomical tides dominate, explaining 65
This short communication describes the variety of cryogenic landforms found at higher elevations in the vicinity of Monte Alvear, Andes of Tierra del Fuego. The survey was undertaken as the first step in a multi-year study in which many
of the cryogenic landforms in this little-studied area are being investigated and monitored.
It is the target of this study to understand the character of the European dimension in actual Portuguese geography textbooks of 7th to 9th grade. A treatment of quantitative and qualitative methods was developed, which corresponds to the demands
of the matter and is suited to achieve a thorough understanding by its straightness and great comprehensibility. By means of quantitative analysis, the study examines how often each European area is mentioned, how many illustrations contain an European dimension
