ASABE member Celso Castro-Bolinaga, assistant professor, and ASABE member Steven Hall, associate professor, will seek to determine if bivalve colonies can reduce scour and erosion and if the adhesive proteins used by bivalves increase sediment strength and reduce erodibility. The NCSU researchers will work with a team at Virginia Tech.
According to Table 4, the weight loss by immersion reduced from 379% in the 60f-40c mixture sample, in its natural state, to 37% in the 60f-40c + 5% CPII-E-32 mixture, in relation to its dry unit weight significantly reducing its erodibility.
Where, A = Soil loss per unit area (tons/ha/yr); R = Rainfall-runoff erosivity factor (index); (MJ/hectare mm/yr); K = Soil erodibility factor (tons/ha/yr); LS = Slope factor (unit less); C = unit less management factor of cover; and P = unit less practice conservation factor.
Soil erodibility is the key parameter for evaluating the susceptibility of soil to erosion and is essential for understanding soil erosion mechanisms and processes (Wang et al.
where Y is the loss (average annual soil in t [ha.sup.-1] y[r.sup.-1]), R is the rain erosivity (in MJ mm [ha.sup.-1] [h.sup.-1] y[r.sup.-1]), K is the soil erodibility (in t h M[J.sup.-1] [mm.sup.-1]), LS is the slope-length factor, which includes slope length and slope steepness factors (booth dimensionless), C is the cover management factor (dimensionless), and P is the support practice factor (dimensionless).
RUSLE predicts erosion based on six factors: rainfall, soil erodibility, slope length and steepness, cover management, and conservation practices (Renard et al.
The ratio of sand and dust content to the clay content as the index of soil erodibility. This is an important criterion to suppose the sensitivity of soil to erosion.
The study used geological surveys to produce an erodibility map.This was combined with socio-economic data to identify which groups were more, or less, resilient to coastal erosion.
Soil map of Son La province at scale 1: 100.000 [17] was used to calculate the soil erodibility factor (K).
Soil erosion receives between 0 and 100 points; the allocation of points exhibits sharply diminishing marginal returns, with no points awarded for an erodibility index below 4, 79 points for an erodibility index of 4, 92 points for an erodibility index of 5, and 97-100 points for erodibility indexes of 6-9.
However, the current understanding of the erodibility of these materials and the interactions between cracked seepage barriers and the water flow is inadequate, where limited data was available to provide the sufficient information regarding the impacts of cement replacements, curing period, erosion time, and sizes of initial cracks.
