Coud I employed RUSLE Model to Estimate soil erosion in monthly scale?
Best Regards
Yes, you could use it at a monthly scale. The R values should be at that scale to get reasonable estimates of soil loss. C value should be evaluated carefully to account for seasonal change in vegetative cover.
Hi Zeinab,
Of course. In RUSLE, mostly the R factor and C factor is temporally changing in all areas.
As Mr. Timothy said, you can use the monthly R factor instead of annual R factor.
Similarly you can use the Cover management factor also in each month ( it is advisable to use the NDVI based C -factor, which reflect more changes than the LULC based, if we consider the the monthly changes).
All other factors such as LS and K remain constant and P factor value you can determine based in the overall pictures (constant conservation practices in the area under consideration).
Good luck

Of course, RUSE and new versions of MRUSLE with the remote sensing data of normalized vegetation index (NDVI)
Yes, of course, RUSLE is a good method.
Remermber that if you have a micro catchment, the best model is the MPSIAC empirical model.
I attach you a paper about the comparison of empirical models to estimate soil erosion.
Best regard. Enjoy.
Emilio.
Hi All
Yes RUSLE is a good option considering the points mentioned above by Mr. Timothy and Vijith, but a problem is also raised about K valve which the previous experiences has shown that it needs to be calibrated in calcareous-stony soils of Iran where Miss Hazbavi is likely going to use it!
All the Best

Hello Dear Dr. Asadi
Thank you so much. In fact I am searching a method to get me a monthly soil erosion.
I want to compare the soil erosion in different month and in different years. Please get me more data about this.
Best Regards
Hello again
Thank you a lot for your responses. Toward this i confident the possibility of RUSLE application for monthly scale.
But i didn't find the paper about it.
Best Wishes
The WEPP model uses daily input, either from observed weather or a stochastic weather file and can generate event, monthly, annual, or average annual outputs. I have used this in the past, and run the model for 100 years of stochastic weather to see how often a runoff event occurred in June for one study, and how often sediment was delivered from snow melt during the winter months for another study. WEPP gives both runoff and erosion predictions, and can be run for a single hill slope, like RUSLE, or for a small watershed.
RULSE is the still best method. It is very important how you determine your input variables? You may use different equations, you can develop new approach too.
Hi Zeinab
Top models can be used to estimate erosion. But several factors influence the choice of a model, such as the dimensions of the watershed, working closely and ….Swat model is more efficient and can be used. Swat model for large watershed and with high accuracy....
thanks
yes RUSLE, have capability for monthly soil loss but your all factor r not monthly changeable except R (rainfall) and C (for Vegitation).
And for monthly C you can estimate C from NDVI (monthly), which give u more changes (Monthly based) than the LULC (yearly changes) based,
also u can use this link

RUSLE does not estimate monthly erosion but annual erosion. I think the best option is eventn - based model.
Even if there is a model for estimating soil losses. There needs to be measures on the ground to get a good estimate
