3.2 Factor R evaluation
In the scope of our study, we utilized meteorological data concerning
daily precipitation over an extensive period from 1990 to 2020. Our
objective was to evaluate the trends of average annual and monthly
precipitation over time in the studied region.
To delve deeper into our analysis, we employed a specific formula known
as the erosivity formula. This formula enabled us to quantify the
potential impact of precipitation on soil erosion. Understanding soil
erosion is crucial as it can have significant implications for
agriculture, land management, and environmental conservation.
By applying this formula, we obtained a critical parameter known as the
”R-value,” expressed in megajoules per millimeter per hectare per year
(MJ.mm/ha.year). In our case, this R-value was found to be equal to
67.18. This value represents the energy intensity of precipitation and
its erosive potential on an annual basis.
Thus, our study provided valuable insights into precipitation patterns
and their capacity to induce soil erosion in the region over the past
three decades. These findings can be utilized to inform land and water
management policies and to develop soil conservation strategies and
erosion prevention measures.
