LS factor: Length and slope factor in RUSLE What is LS-Factor ?? If we study soil loss in a river basin or in a particular area, then we summaries the several factor that are participating in soil erosion or indirectly hit the erosion activity in that area. Among them most important factor is the topography which directly hit the erosion process in the area. The influence of topography in soil erosion can be assess using the topographic factor ( LS factor ) which is used in RUSLE model to calculate the soil erosion in a river basin. It contains simply two component as slope length factor (L-factor) and slope steepness actor (S-factor). This means length and steepness (gradient) of slope affect the soil erosion in a river basin and as length and steepness will increase, it lead to increase in erosion in that area. Before studying the influence of L-factor in soil erosion, it is necessary to know L- factor. What is Slope length factor (L-factor)?? The L-factor ( Wisc...
Cover management factor in RUSLE model (C factor) What is C-factor? C factor is cover management factor and it reflect by its name that it is soothing like the management of cover types. C-factor depend on land surface cover types like barren land, waterbody, urban, vegetation types and stage of vegetation growth. C-factor is simply the ratio of soil loss from land surface when management practices are involved and soil loss without management practices. Soil erosion can be assess using c-factor and it helps to analyze the roll of cropping and management practices on erosion rates. 📥📥 Download Global soil erosion data How C-factor is helpful assessment of soil erosion?? C-factor commonly used to assess annual soil erosion in revised universal soil loss (RUSLE) equation which is as follows:- A=R*K*LS*C*P Where A = annual soil loss, R = rainfall erosivity factor, K = soil erodibility factor, LS = slope length and steepness factor, C = cover ...
