Indeed soil texture has a great effect on erosion especially on the erosion rate. This is more important on a ground sandy or loamy soil on a clay texture
Dear Ahmad, you can find these papers easily in internet. Caly is more resistente to erosion than sand soils... If you have a specific ask could be more easy to do a direct answer.
K, soil erodibility factor, is commonly found in soil surveys. Erodibility is principally influenced soil texture the organic content can also have an effect. Look for studies using the Universal Soil Loss Equation (USLE) (or the Revised... (RUSLE) or Modified...(MUSLE)). Here's a table that shows varying K factors (just a table pulled off the internet, you should find the original source): http://mepas.pnnl.gov/mepas/formulations/source_term/5_0/5_32/5_32.html
Indeed soil texture has a great effect on erosion especially on the erosion rate. This is more important on a ground sandy or loamy soil on a clay texture
SEE FACTOR K (erodability) of USLE-RUSLE equation in any soil conservation text book
(K-factor) it is a measure of the susceptibility of soil particles to detachment and transport by rainfall and runoff. For one soil, K factor is the rate of erosion per unit erosion index from a standard plot. Texture is the principal factor affecting Kfact, but structure, organic matter, and permeability also contribute.
K is function of (Goldman et al., 1986): particle size parameter; organic matter, soil structure index, profile-permeability class factor, percent clay.
However, sandy-loam and clay-loam seem to have similar K....according the table in the art provided and linked by Jennifer L. Psillas above....
Huge impact soil texture has on their erodibility . This is the most frequently raised issue. Heavier the texture , lesser is the erodibility . Hence , clay soils are more safeguarded against erosion compared to sandy soils.
Dear Ahmad-Please find attached paper on erosion from red and black soils at ICRISAT, Patancheru center. It is a very well conducted experiment in a small watershed. Results are interesting and also help in better understand the erosion issue.
If you want to compare soil erodibility, I agree with using the K factor of the USLE/RUSLE. So, you will be able to compare your soils with others in different regions of the worlds. For that, you must have good soil samples. You must have in account that silt (0.002-0.05 mm) and very fine sand (0.05-0.1 mm) are the soil texture fractions which have more influence in erodibility.
As has been rightly responded to by other researchers, erosion is certainly greatly affected by texture particularly when the fines that act as clogs in between the particles are lacking. in other words the more loosely bound these particles are the more they are prone to erosion.
In the case of water erosion, soil erodibility increases with increase in the size of soil separates. Soils with greater sand in their distribution have more macropores and less flocculating agents, which permits more water, increases their tendency to detach from each other and be transported by water. It is a reverse case in soils with higher clay proportion with smaller sizes and tightly bonded to one another.
la réponse est claire, les deux textures sont sensibles à l'érosion pour une pente de 2 à10% et un couvert végétal de 30 à 40%, selon le diagramme que j'ai développé! L'érosion est de 50 à 60%. Clay-Loam est plus résistant, mais Sandy-Loam est moins résistant. Je peux vous en voyer le diagramme si vous voulez
1 les textures Clay loam et Sandy-Loam ontun comportement différent: la première est moins sensible à l'érosion que la deuxième, son facteur K(perméabilité) est moins grand.La deuxième avec un facteur K (perméablitè) plus grand,est plus sensible à l'érosion. 2 la matière organique, joue un rôle 3 la pente est un facteur déterminant 4- la couverture végétale joue aussi un rôle. Le diagramme de l'érosion que j'ai développé, donne pour chaque texture et selon la pente et la végétation un taux différent d'érosion. Ainsi, pour Clay Loam, pour une pente de 5 à 10% et un couvert végétal de 30 à 40%, l'érosion est de 20à 30%. Pour Sandy Loam, dans les mêmes conditions, l'érosion est de 55 à 60%, selon mon diagramme.
Soil texture (which refers to relative proportion of sand, silt and clay) definitely affects the soil erosion. Soils having greater sand particles are prone to erosion compared to soils having greater clay content.
Texture of soils certainly affect soil erosion. The loose particles especially sand have greater influence on the erosion of soils than when fine particles are involved, the fines i.e. silt and clay show more resistance to erosion.
Soil texture certainly has effect on erosion phenomenon. As it is mentioned in some answers you can use Universal Soil Loss Equation (USLE) or some other method.
For a fast estimation of values of K factor I send you one table. To see the effect, I can suggest to do the variation of a parameter in some expected range, while other parameters shall be "constant" in an analyses.
Charles , find some interesting facts about the issue , you raised , hope you will like them:
The differences in topsoil erodibilty appear to be directly related to slope morphology and to the specific morphodynamic features. The observed relationships reflect the possibility to better evaluate both the soil erodibility factor (K) used within the USLE equation and the spatial variability of physical and chemical soil characteristics on the basis of digital terrain analyses, and so better predict soil loss rates.( Source : Colombo et al , 19th World Congress of Soil Science, Soil Solutions for a Changing World 1 – 6 August 2010, Brisbane, Australia. Published on DVD).
Physical characteristics of rainfall such as drop size and drop-size distribution, rainfall intensity at short intervals and kinetic energy of rainfall were evaluated using different methods. Thus, compound erosivity indices were evaluated which showed a similar trend in annual rainfall erosivity with annual rainfall amounts rainfall amounts. Attempts have also been made to use geostatistical tools and fractal theory to describe temporal variability in rainfall erosivity. High erosivity aggravates the vulnerability of coarse-textured soils to erosion. These soils, high in sand content were poorly aggregated and structurally weak. Thus, they were easily detached and transported by runoff. Long-term data are needed to describe factors of soil erosion in the tropics but quite often, equipment are not available or poorly maintained where available such data useful data are not collected. A greater cooperation of pure physicists, soil physicists and engineers in the developing nations is needed to improve or design equipment and methods for the characterization of factors of soil erosion in the tropics.Source : ,Susceptibility of Coarse-textured Soils to Soil Erosion by Water in the Tropic by s F.K.
