Generally, the evaluation and assessment of the critical condition of rill formation are useful for a better understanding of soil erosion processes. The inherence characteristics of soils, which have much dynamic variations on the hillslopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. This study aims to assess experimental rill incision ...

In addition to Erodibility of sediment particles in river increase river sediment load, they are important factors in morphological changes. In the rivers that erodibility is high, trend of morphological changes are intensive that in this case, river is unstable. On the contrary, it will lead stability and low changes of the river. Study area of this research is Saraskanchay that has been locat...

Reduction of species diversity which is a significant threat to the earth has been found more important and has attracted attention among ecologists over recent years. This research was carried out to determine the relationships between plant species diversity indices and soil properties by multivariate regression methods in Jamilabad region, Baft, Kerman province, Iran in 2016. Different sites...

Abstract Delta evolution in the context of no sediment discharge has become a global concern, and an accretion-to-erosion conversion is occurring Yangtze estuary. This could threaten Changjiang subaqueous delta development. Sediment erodibility important indicator vulnerability. However, present future remains unclear. In this study, 37 short cores were collected from delta, critical shear stre...

Observations of bridge abutment scour lead to a practical new approach for estimating realistic scour IIHR-Hydroscience and Engineering depths at bridge abutments. Prior design approaches usually led to unrealistically deep estimates of abutment scour depth. The observations presented stem from flume experiments conducted with abutments with approach embankments subject to a range of erodibilit...

Erosion is a severe threat to the sustainable use of agricultural soils. However, structural resistance soil against disruptive forces steppe soils experience under field conditions has not been investigated. Therefore, 132 topsoils grass- and cropland covering large range physico-chemical properties (sand: 2–76%, silt: 18–80%, clay: 6–30%, organic carbon: 7.3–64.2 g kg−1, inorganic 0.0–8.5 pH:...
