Abstract:
La poussière minérale atmosphérique résultant de l’érosion éolienne des sols affecte le système terrestre. La distribution en taille (PSD) de cette poussière joue un rôle clé dans le bilan radiatif et la chimie atmosphérique, la formation des nuages et la productivité des écosystèmes terrestres et marins. Néanmoins les modèles climatiques peinent à reproduire précisément la PSD de la poussière émise. Ceci vient de la représentation imparfaite des mécanismes d’émission de poussières et des vitesses de vent de surface associées. C’est particulièrement vrai en présence d’éléments de rugosité de s

Riparian buffers are promoted for water quality improvement, habitat restoration, and stream bank stabilization.

Abstract:
The geomorphic and geochemical characteristics of landscapes impose a physical template on the establishment and development of ecosystems. Conversely, vegetation is a key geomorphic agent, actively involved both soil production and sediment transport. The evolution of hillslopes and the ecosystems that populate them, are thus intimately coupled; their co-dependence potentially has a profound impact on the way in which landscapes respond to environmental change.

The effect of variation in slope was assessed for each treatment. Cover and density were significantly different (Ps0.05) during the first and second year of sampling.

Abstract Water level regulation for purposes of hydropower production has caused notable changes in the littoral zones of regulated lakes in northern Finland.

Changes in the environmental conditions and aquatic macrophyte communities were studied largely by comparing the regulated Lake Ontojärvi and the unregulated Lake Lentua in the Kainuu area.

Natural interactions between riparian vegetation, large woody debris (LWD) and the fluvial geomorphology of forest streams in North America and Europe have been well researched.

Paleovegetation data suggest that portions of WGEW higher than approximately 1430 m a.s.l. have been grasslands and/or woodlands throughout the late Quaternary, while elevations lower than 1430 m a.s.l. changed from a gras

Les geotextiles utilises dans la lutte contre l'erosion ont pour but d'aider a l'installation d'une couverture vegetale tout en protegeant les sols. Or aucune caracteristique specifique et aucun critere de dimensionnement n'est actuellement propose pour savoir si les geotextiles utilises sont efficaces pour limiter l'erosion et assurer une bonne vegetalisation. C'est ce que nous avons tente de determiner. D'une part des essais specifiques ont ete developpes pour caracteriser les geotextiles utilises en protection contre l'erosion, en particulier la mesure de l'amortissement de l'impact des gou

Abstract:
The application of mulch products to disturbed soil is frequently used to decrease soil erosion. The addition of polyacrylamide (PAM) has been demonstrated to reduce erosion even further. We conducted rainfall-simulator and field tests on several types of mulch, hydromulch, and erosion control blankets with varying rates of PAM to determine the relative improvements in erosion control and vegetative establishment achieved by different groundcovers and PAM. We also compared applications of granular (37 and 74 kg ha-1) and aqueous (37 kg ha-1) PAM with straw. The tests were done on 2- x 1-m soil

Abstract:
Dans le contexte d'augmentation de la pression démographique et des risques liés aux changements climatiques, la question de l'érosion est de plus en plus cruciale. La gestion actuelle des milieux des montagnes méditerranéennes, particulièrement affectés par ces phénomènes, repose sur une bonne connaissance de leurs sensibilités à l'érosion et de leurs trajectoires à long terme. Une approche rétrospective des trajectoires des environnements a été menée par l'étude de trois archives sédimentaires lacustres prélevées dans les Alpes du Sud (lacs Petit, Vens et Allos).

Abstract:
This project uses a Geographic Information System (GIS) as a tool for estimating soil erosion on a watershed scale. A new and key tool for managing ecosystems in North America are resource management plans based on watershed areas. Watershed management plans are a response to widespread concern about the cumulative effects of nonpoint source pollution (such as agriculture pollution) on water resource quality.The primary objective of this project was to develop a method using GIS to estimate the annual gross erosion for each of the watersheds. Sediment delivery was calculated within each of the

Abstract:
Previous field demonstration projects in metro-Atlanta have shown that seep berms, which are elongated sedimentation basins at the outlet of a disturbed land area, can provide high suspended sediment trap efficiencies with respect to coarse sediments on construction sites having drainage areas greater than five acres. Previous literature has shown that vegetative filter strips are efficient traps for fine suspended sediment in stormwater runoff. A combination of a seep berm and vegetative filter in series was studied in this thesis as an erosion control measure with quantification of its flow
