What is erosion research?

Erosion is the displacement of solids (soil, mud, rock and other particles) by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion).

What is a method of erosion?

Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.Mar 20, 2018

Why Is Erosion Control Important? Without erosion control, your topsoil may lose its ability to hold nutrients, regulate water flow, and combat pollutants. In addition to affecting the ecosystem of nearby wildlife, residential properties and transportation systems can suffer long term damage.May 8, 2020

Is tooth erosion a multifactorial background?

Dental erosion is considered to have a multifactorial background in which individual and lifestyle differences are important. Despite the methodological differences in research, data from many countries confirm that tooth erosion which progresses rapidly is common in children and young people (4). While the concentration of hydrogen in plaque fluid is the main determinant for erosion

Does fluoride prevent tooth erosion?

Sodium fluoride-containing toothpastes can prevent the loss of material caused by erosion, but their effects are limited, especially against severe tooth wear. Fluoride causes remineralization of the enamel with the formation of calcium-fluorine-like components on the tooth surface. At the same time, however, some research suggests that abrasive ingredients present in toothpastes prevent precipitation (3, 17). Although all fluorides help to strengthen teeth against caryogenic acids, the current fluoride sources do not provide the same degree of erosion protection. The daily use of a stabilized stannous fluoride tooth cleaner has been shown to be the most effective way of protecting teeth against the risk of tooth wear (18, 19).

What are protease inhibitors used for?

Recent studies have focused on the role of protease inhibitors on erosion. The use of protease inhibitors in dentine tissue to protect the organic matrix after an erosive attack may have a protective role against future mineral losses. However, in spite of promising results in in situ studies, these preventive measures are not evidence-based. Clinical trials are required to confirm these findings and establish the protocols to be used (16).

What is the purpose of oil in pellicle?

Oils in the pellicle protect the tooth tissues against decreasing pH. In one study, it was observed that it protects the tooth surface against abrasion. Use of oils with fluoride-containing agents may be recommended (3).

Is chitosan an antibacterial?

Chitosan is an antibacterial agent that contributes to tissue regeneration. It may be present in toothpastes. It has anti-erosive properties as it has high positive charge at acidic pH. It may prevent the formation of dental erosion by forming a protective layer on the teeth by connecting to the pellicle (13).

Which metals have the strongest effect on erosion?

Metal ions such as stannous and titanium, have strong effects on erosion. Stannous fluoride, stannous chloride or titanium tetrafluoride are some of these materials (13).

What is CPP APC?

Casein phosphopeptide-amorphous calcium phosphate (CPP-APC) is a compound with remineralization effect, and can be added to mouthwashes and gums to prevent erosion. However, some studies indicate that it is insufficient to prevent erosion (22, 23).

How does soil erosion affect the environment?

This process has an effect on the environment including loss of soil fertility, reduction of water bodies' depth (lakes, ponds, reservoirs, etc.), increase in water turbidity, flood hazard problems, etc. Identifying the erosion hotspot areas using different techniques is an essential tool for sustainable natural resources management. This study focusses on the mapping of soil erosion-prone areas of Ribb watershed, Upper Blue Nile, Ethiopia. This study aimed to identify the erosion of hotspot areas for the setting of effective soil and conservation strategies. Different soil erosion contributing factors, viz. Slope, land use, soil, rainfall, and stream power index, were integrated on ArcGIS 10.3 environment for determining the erosion-prone areas. Multi-criteria decision analysis (MCDA) technique was used to develop erosion hotspot areas using thematic layers pair-wise comparison tool. The weights for each thematic layer and feature were decided based on the expert's judgment and review of the literature. Hence, the results of soil erosion map showed very high, high, moderate, low, and very low vulnerability to erosion with areal coverage of 7.04%, 20.40%, 17.60%, 32.01%, and 22.95%, respectively. The findings of this study will help decision-makers to plan and carry out effective soil and water conservation practices in highly vulnerable areas to soil erosion. MCDA was found as a basic tool for determining erosion-prone areas coupled with GIS. The spatial distribution map indicated that most of the erosion-prone areas were found in northern, eastern, and northeastern parts of the watershed due to the steep slope and agricultural practice which needs integrated soil and water conservation practice.

How does mulching the soil reduce water infiltration?

Mulching the soil surface with a layer of plant residue is considered an effective method of conserving water and soil because it increases water infiltration into the soil, reduces surface runoff and the soil erosion, and reduces flow velocity and the sediment carrying capacity of overland flow. However, application of plant residues increases operational costs and so optimal levels of mulch in order to prevent soil and/or water losses should be used according to the soil type and rainfall and slope conditions. In this study, the effect of wheat straw mulch rate on the total runoff and total soil losses from 60-mm simulated rainstorms was assessed for two intensive rainfalls (90 and 180 mm h−1) on three slope gradients typical conditions on the Loess Plateau of China and elsewhere. For short slopes (1 m), the optimal mulch rate to save water for a silt loam and a loam soil was 0.4 kg m−2. However, for a clay loam soil the mulch rate of 0.4 kg m−2 would be optimal only under the 90 mm h−1 rainfall; 0.8 kg m−2 was required for the 180 mm h−1. In order to save soil, a mulch rate of 0.2 kg m−2 on the silt loam slopes prevented 60%–80% of the soil losses. For the loam soil, mulch at the rate of 0.4 kg m−2 was essential in most cases in order to reduce soil losses substantially. For the clay loam, 0.4 kg m−2 may be optimal under the 90 mm h−1 rain, but 0.8 kg m−2 may be required for the 180 mm h−1 rainstorm. These optimal values would also need to be considered alongside other factors since the mulch may have value if used elsewhere. Hence doubling the optimal mulch rate for the silt loam soil from 0.2 kg m−2 or the clay loam soil under 90 mm h−1 rainfall from 0.4 kg m−2 in order to achieve a further 10% reduction in soil loss needs to be assessed in that context. Therefore, Optimal mulch rate can be an effective approach to virtually reduce costs or to maximize the area that can be treated. Meantime, soil conservationist should be aware that levels of mulch for short slopes might not be suitable for long slopes. Keywords: Straw mulch, Soil losses, Runoff, Rain simulator

What are the causes of degradation in peatlands?

Once they are drained to provide optimal crop growth conditions, however, a series of degradation processes is generated. Wind and water erosion, subsidence and soil organic matter oxidation are the main causes of degradation observed in cultivated histosols. This study evaluated the decomposition dynamics and chemical changes of three biomass crops during an in‐situ incubation in a cultivated histosol. The decomposition dynamics characterized in the field study were then used in a simulation to determine if sustainability could be reached by using biomass crops as a soil amendment. The results showed that an exponential decay fitting curve best represented the weight loss of sorghum (Sorghum bicolor (L.) Moench) in the in‐situ bags over time, while a logistic fitting curve best represented that of miscanthus (Miscanthus X giganteus) and willow (Salix miyabeana). The quality of the crop determined the initial and overall decomposition dynamics observed. The loss of carbon from the crushed biomass crop was much more important in sorghum than in miscanthus and willow. The long‐term simulation of histosol amendment revealed that using miscanthus and willow at input rates of 7.5 and 10 T of carbon per year, respectively, would be sufficient to ensure sustainability. Improving knowledge on carbon loss in cultivated histosols as related to soil and crop management would help in developing a soil amendment program at the farm scale. In addition, more knowledge is needed to determine the impact of long‐term and successive amendment with biomass crops on the physical and biochemical properties of histosols.

What is water erosion?

Water erosion is the removal of the top layer of land by water from irrigation, rainfall, snowmelt, runoff, and poor irrigation management. Ultimately, rainwater is most frequently to blame when it comes to this issue. The flowing water moves the soil organic and inorganic particles alongside the land surface, depositing them in the lower landscape.

Why is water erosion important?
