- This paper jointly analyses multitemporal, multispectral ASTER data, continuous river stage and discharge data, and field observations of the growth rates of the dominant riparian tree species (Populus nigra) along a 21 km reach of the Tagliamento
- River, Italy. The study period (2004-2009) of increasing flow disturbance allows the exploration of vegetation dynamics within the river's active corridor under changing flow conditions. The analysis demonstrates the utility of ASTER data
- for investigating vegetation dynamics along large fluvial corridors and reveals both spatial and temporal variations in the expansion, coalescence, and erosion of vegetated patches within the study reach. It is illustrated that the rate of growth of riparian trees

- The AA. evaluate several functions that have been proposed to describe the variation in mass flux density with height of wind-blown sediment, with the flux containing a mixture of particles in suspension and saltation, based on detailed field data
- density profiles reasonably well. The results suggest that the decay with height of mass flux density of sediments dominated by saltation particles as in the present study tends to follow a modified exponential function law, but a modified power function

- has received much less attention compared to field-based studies. There are also some other aspects, such as threshold determination, geological control, inheritance, application of geo-informatics and focus on low-energy and tropical coasts, that have
- received limited attention. To enable a better understanding of platform dynamics in a particular area, fieldwork, laboratory simulation and numerical modelling should be carried out simultaneously. Shore platforms are a global feature, and their study

- Block removal and step backwearing as erosion processes on rock shore platforms: a preliminary case study of the chalk shore platforms of south-east England
- A combination of soft copy photogrammetry, ortho-rectification, geo referencing and field measurement of step height are linked in a GIS environment to measure step retreat on chalk shore platforms at sample sites in the south of England over 2

- Two types of landforms attributed to the geomorphological effects of long-lasting snow accumulations, snowpatch hollows and pronival ramparts, were studied in the Krkonoše Mountains, Czech Republic. Factors influencing the distribution
- and morphology of snowpatch hollows were examined using statistical analysis of field-measured and DEM-modelled snowpatch hollow characteristics. Snowpatch hollows were classified into two groups. The age and degree of activity of pronival ramparts, occurring
- only at two sites in the study area, were determined using several methods (Schmidt hammer, lichenometry, pollen analysis, and radiocarbon dating). The appearance of these pronival ramparts differs between the two sites as a result of the different

- The aim of this study was to test, under field conditions, the response of runoff, soil erosion, nutrient, carbon losses, and heavy-metal transport to different plant covers, including aromatic and medicinal plants and native vegetation during two
- hydrological years. The study area is located in a coastal area of the south-eastern part of the Iberian Peninsula at Almuñécar (Granada, SE Spain). The results support the recommendation of using plant covers with multiple purposes (aromatic–medicinal–culinary

- This study uses oxbow lakes to ascertain the extent and nature of change in a river's form, focusing on the effects of post-1950s floodplain gravel extraction on the geomorphology of the Leaf River in southeastern Mississippi, USA. Data from 12
- cross-sections suggests that the present-day river is 35% wider and 12% shallower than the cross-sectional geometry in cutoffs that pre-date 1955. Field measurements reveal that the Leaf River was relatively stable from at least 1911 to the early 1940s
- , but has since undergone an average of 2.65 m of degradation in the study reach. Survey data from a nearby USGS stream gage show that degradation began abruptly in the mid 1970s, most likely as a result of in-stream mining and pit avulsions on a major

- The collapse of gully walls is an important mode of gully erosion, and it depends strongly on 2 soil shear-strength parameters : cohesion and the internal friction angle. In this study, the AA. sampled 6 groups of surface soils from 4 different land
- density, water content, crack depth, and the width of the soil collapse. The model predicts that soil collapse would occur at 2 levels of water content: dry and wet conditions. Field data showed that collapse only occurred under the wet condition

- yields increase as scale increases, and it is proposed that this effect, which differs from that observed in the few other studies of scale effects undertaken, is due to increasing connectivity within the catchment, and the dominance of preferential flow
- pathways including through macropores and field drains. The processes contributing to scale dependence in the data, and the possibility that certain processes dominate at particular scales, are discussed.

- This article presents the results of hydromorphological inventorying of River Ropa (Low Beskids range) using the River Habitat Survey method, which has hitherto been used on the lowland rivers of central and northern Poland. To study
- the valorisation of the river, two sections of the Ropa – above and below the Klimkowka Reservoir and its dam – were selected. On the basis of the results of field mapping, the two basic indicators were calculated, i.e. habitat quality using the indicator

- Classification and regression tree (CART) analyses were undertaken to test the usefulness of including vegetation variables in mountain permafrost distribution models for 5 widely spaced study areas in the Yukon. Digital elevation model (DEM
- )-derived variables, field-derived vegetation variables and satellite imagery-derived vegetation variables were employed individually to classify sites into permafrost probable, permafrost improbable and permafrost ‘uncertain’ categories. The vegetation

- This paper reports the results of oxygen (andO 18) and hydrogen (andD) isotopic analyses of ice wedges and a five-year monitoring programme on the ice-wedge thermal regime at three sites in northern Victoria Land. The purpose of the study
- values and observations of hoarfrost crystals in ice-wedge cracks during summer field surveys indicate that sublimation processes control the formation of ice in wedges, especially at high elevations within this region.

- Using geographic information system (GIS) and field measurements the nearshore morphological variability of a headland bay beach at Tenby, West Wales, is assessed over historical time frames (1748-2007). Inter-linkages between nearshore

- Seasonal variability of microbial biomass carbon (MBC) and basal respiration (BR) in surface soil was compared between conventional straw removal (SR) and straw coverage (SC) in a maize field experiment, Northeast China. The straw coverage treatment

- A method of delineating Colluvial soils is proposed by applying a combination of high resolution digital elevation model analysis and detailed field survey. Two models based on fuzzy classification of soil units were created using different
- topographic derivatives as the only input parameters to predict the Colluvial soil area on a morphologically diverse study site in the Southern Moravia, Czech Republic. The model that considers only the derivatives with a strong relationship to Colluvial soil

- Since 1999, the program of “Grain for Green” has been implemented in the semi-arid Loess Plateau, China. In this study, the changes in soil organic carbon (SOC) stocks due to the vegetation restoration in the middle of Loess Plateau were estimated
