- Results from plot scale studies on the effectiveness of live barriers for soil erosion control on steep mountains in Cochabamba, Bolivia are used to evaluate the European Soil Erosion Model (EUROSEM). A three hectare catchment with 28 fields
- and slopes of 20 to 30 % is also tested. After EUROSEM is parameterized for local conditions, it is used to simulate the likely impact of live barriers of Phalaris grass on catchment-wide soil erosion rates. - (SLD)

- Geomorphological response of the East Frisian barrier islands to sea-level rise: an investigation of past and future evolution
- Climatic warming ; Deglaciation ; Germany ; Global change ; Greenhouse effect ; Holocene ; Island ; Lagoon ; Model ; Nature conservation ; North Sea ; Quaternary ; Sea level
- Post-glacial sea-level rise has resulted in shoreline erosion in many places. Sandy barrier islands migrate in a landward direction in order to compensate for the rise in sea-level. Several models for the possible response of the East Frisian
- barrier islands and tidal flats to the Holocene sea-level rise are summarized.
- Effectiveness of vegetation barriers for marly sediment trapping
- Relationships between eroded zones and vegetation barriers - composed of low vegetation, that is to say herbaceous and under-shrub layers - located downslope and sufficient to stop all the sediments eroded above, have been studied in the Brusquet
- experimental marly catchment in the French southern Alps. The eroded zones and the vegetation barriers were characterized by their surface areas, between which an average linear relationship exists. Results also showed that, for a marly plot with a given
- surface area, a downslope vegetation barrier covering only 20 per cent of this plot can be sufficient to trap all the sediments eroded above it.

- Analyse des données concernant les barrières géochimiques présentes dans les travaux scientifiques sur l’étude des paysages. L’A. regroupe ces barrières selon différents critères : fonctionnels, génétiques, chronologiques, topologiques, etc
- . L’approche génétique dans l’étude des barrières géochimiques est décrite tout particulièrement du point de vue de son importance pour la résolution des problèmes écologiques et environnementaux.
- Morphology of the Itapeva to Tramandai transgressive dunefield barrier system and mid- to late Holocene sea level change
- sea level changes. The AA. argue that the effect on barrier development was to suppress the development of a drainage system during the rising and maximum stages, and encourage the development of an organized drainage system in the form of regularly
- The surface morphology of the transgressive dunefield barrier extending from Itapeva to Tramandai along the northern littoral of Rio Grande do Sul, is examined and an attempt is presented to link morphological changes across the barrier to Holocene
- spaced washouts during the falling period, and that this change in sea level from rising to falling therefore produced the large-scale differences in barrier morphology.
- Implications of live barriers for slope stability in Andean hillside farming systems
- Agropédologie ; Andes ; Barrière végétale ; Bolivie ; Eau du sol ; Erosion des sols ; Infiltration ; Modèle ; Montagne ; Simulation de pluie ; Versant
- A. discuss a methodology, based on EUROSEM, SLOPE/w and SEEP/w models, for quantifying the effects of live barriers on the stability of agricultural land in the Andean valleys of Bolivia. The methodology involves computer simulation of slope
- hydrology of a translational landslide to obtain probable storm characteristics and parameters for the antecedent site condition. Then a steep agricultural plot is modeled for slope instability with various arrangements of Phalaris grass as a live barrier
- . The grass barriers would increase infiltration and reduce slope stability in extreme conditions, but not enough to make slope failure imminent. - (SLD)

- Road construction and agricultural activities contribute to habitat isolation. Field studies suggest that roads represent barriers and cut off the gene flow by dividing animal populations into fractions on either side of the road. Several mobility
- diagrams show significant isolation effects of roads on population of forest-dwelling mice (Apodemus flavicollis) and carabid beetles.
- The effects of vegetative barrier strips on surface runoff and soil erosion in Machakos, Kenya. A statistical versus a spatial modelling approach
- The main hypothesis of this study is that a contour hedgerow system can be a viable alternative to the fanya juu barrier system for effective erosion control on moderately steep slopes in sub-humid / semi-arid Machakos. An on-station field
- experiment was conducted to evaluate the effectiveness of contour tree hadgerows and grass strips for soil and water conservation. - (AGD)

- Spatial barriers : concepts, use and an application to intra-regional migration
- The analysis of the boundary effects for individual groups of migrants in the Katowice region indicated, similarly to the Warsaw agglomeration a positive correlation between age and the social position, which implies the intelligentsia's
