Erosion

To find the threshold in marsh resilience to oil spills Brian R. Silliman and his team studied the erosion rates along Gulf of Mexico coastline following the Deepwater Horizon disaster in the summer of 2010. Before data collection began the relationship between the marsh erosion rates and the degree of plant stem oiling was predicted to be positively correlated. The greatest salt marsh erosion sites and the threshold for marsh resilience were forecasted to occur at the highest (90-100%) stem…

barrier beach system where they are focusing on the constraints of the road and the defences on the barrier. In this case Chadwick et al focussed on the defences comprised of rock armour and concrete block mattresses and found that they slowed the erosion of the wave crest and cause the beach to steepen. They also stated that the road also had a ‘marked impact’ as it prevented shingle thrown ‘landward of the beach crest forming a new landward crest.’ This strongly indicates that the defences…

Egypt receives less than 80 mm of rainfall a year, and only 6 percent of the country is arable and agricultural land, with the rest being a desert. This leads to excessive watering and the use of wasteful irrigation techniques such as flood irrigation an outdated method of irrigation where gallons of water are pumped over the crops. Desertification is a land degradation problem of major importance in the arid regions of the world. Deterioration in soil and plant cover have adversely affected…

investigate the variables that influence erosion rates in a stream. Sediments that were eroded at or near Linganore High School end up in the Chesapeake Bay. Sediments eroded from rocks in Linganore Creek and are carried to the Monocacy River. From there, the sediments are taken to the Potomac River. The Potomac River’s water and anything loose in it are dispensed into the Chesapeake Bay. Water transports the material from Linganore to the Chesapeake Bay. Erosion is the process of rock being…

ruining the home of the world’s most endangered tribe, the Awá, along with many other native tribes (Chamberlain, 2012). Deforestation simulations have shown an increase in temperature and a decrease in rainfall, which cause desertification, soil erosion, and flooding (Lejeune, Davin, Guillod, & Seneviratne, 2015). Not to mention, forests are home to 80 percent of the world’s biodiversity. Deforestation is liable for the loss of 137 plant, insect and animal species daily (Cho,…

Other forms of environmental degradation bauxite mining causes are due to is residue. Bauxite residue or red mud has vast affects on the ecology. The most common problems red mud causes are “wind erosion and groundwater pollution.” (Xue et al. 2015) Currently “there are four major disposal routes, including marine and slurry disposal, dry stacking, and dry cake stacking.” (Xue et al. 2015) Marine disposal poses a large problem in that it causes grave…

most of the year. By contrast, cattle had to be kept indoors during winter months and provisioned with hay collected during the summer and then stored. As rapid anthropogenic deterioration of the Icelandic environment, including deforestation and erosion (Amorosi et al. 1997), put added subsistence pressure on Icelandic households, an economic focus on cattle was retained only by households with enough wealth and resources to invest in rearing animals that displayed status and provided the…

soil and plant life unable to prosper. While little plant life can thrive, the level of soil compaction does make it ideal for constructing buildings as the soil is stable. With there being a level slope and little water infiltration there is little erosion occurring, again making the soil ideal for the purpose it is currently intended which is…

Larger sediments such as sand and gravel from the glacial melt water were deposited first in the stream delta forming rolling glaciofuvial silts and sands (Anderson and Cerowiak 2010). After the glacier retreat, these landscapes were impacted by wind erosion and formed aeolian deposits such as sand dunes and silty deposits (Perrapirce et al.…

This report presents a number of findings that are based on the natural landscape of The Spit, such as the geomorphic processes that have shaped The Spit and the geographical features. The Spit contains many geographical features, both natural and built. A natural geographical feature that was identified was headlands. These boulders were being constantly eroded due to abrasion waves, causing bits of rock and sand in the waves to grind down surfaces of the rock. Other natural features sighted…
