SWIM, L.W., JR., ELLIOTT, K.J., OTTMAR, R.D., and VIHNANEK , R.E. 1993. Site preparation burning to improve southern Appalachian pine-hardwood stands: fire characteristics and soil erosion, moisture, and temperature. Can. J. For. Res. 23: 2242-2254. Three southern Appalachian stands with sparse and unproductive pine-hardwood overstories and dense Kalmia latifolia L. understories were treated to...
Erosion reduces soil productivity and causes negative downstream impacts. Erosion processes occur on areas with erodible soils and sloping terrain when high-intensity rainfall coincides with limited vegetation cover. Timing of erosion events has implications on the selection of satellite imagery, used to describe spatial patterns of protective vegetation cover. This study proposes a method for ...
Crops are one of the main factors affecting soil erosion in sloping fields. To determine the characteristics of splash erosion under crop canopies, corn, soybean, millet, and winter wheat were collected, and the relationship among splash erosion, rainfall intensity, and throughfall intensity under different crop canopies was analyzed through artificial rainfall experiments. The results showed t...
SEMENIUK, V., 1994. Predicting the effect of sea-level rise on mangroves in northwestern Australia. Journal of Coastal Research, 10(4), 1050-1076. Fort Lauderdale (Florida), ISSN 0749-0208. The patterns of mangrove distribution in tropical northwestern Australia are related to coastal dynamics, habitats and salinity. They also respond to the sedimentology of the tidal flats that back them, to c...
Land degradation is becoming one of the severest environmental issues in the world, especially in developing nations. Land degradation, usually accompanied by soil erosion, always results in a decrease or complete loss of land productivity, and produces on-site and off-site pollution to soil and water. The methods for land reclamation are various, including physical, chemical and biological. Th...
Soil erosion is a complex process that results in soil and fertility losses from agricultural land and, ultimately, leads to river sedimentation. This study aimed assess various influential factors processes affecting recommend suitable site-based Erosion Control Measures (SECM) for sustainable agriculture while minimizing the downstream rivers reservoir sedimentation Sebeya watershed of Rwanda...
The 2008 Wenchuan earthquake and associated co-seismic landslide was the most recent expression of the rapid deformation and erosion occurring in the eastern Tibetan Plateau. The erosion associated with co-seismic landslides balances the long-term tectonic uplift in the topographic evolution of the region; however, the quantitative relationship between earthquakes, uplift, and erosion is still ...
Soil erosion has been occurring over the geological time. Inappropriate human activities accelerate this process. Soil erosion by water is a widespread problem throughout Europe. The South and Southeast regions of Europe are significantly prone to water erosion. In parts of the region, erosion has reached a stage of irreversibility and in some places erosion has practically ceased because there...
Understanding how long-term abiotic and biotic processes are linked at a landscape level is of major interest for analyzing future impact on humans and the environment from present-day societal planning. This article uses results derived from multidisciplinary work at a coastal site in Sweden, with the aim of describing future landscape development. First, based on current and historical data, ...
