Erosion is a critical aspect of watershed management, driven by numerous natural and anthropogenic forces. Natural factors influencing erosion include precipitation, soil composition, slope length, and slope gradient. Land use is an anthropogenic component shaped by diverse human activities. The calculation of erosion within a watershed is significantly influenced by this element. This study aimed to examine land use alterations in the Cielunca catchment area, the erosion rate resulting from these land use changes, and the dynamics of erosion classification changes in the Cieluenca catchment area from 2004 to 2014. The study's results indicated a variation in the CP value from 0.5 to 0.6, signifying a transformation in land use within the catchment area of the Situ Cileunca. Erosion at a rate in the year 2004 is 325,408 t/ha/y (heavy erosion) and 2014 is 474,832 t/ha/y (heavy erosion). The erosion rate increased 46% from 2004 until 2014.

摘要

Erosion is a critical aspect of watershed management, driven by numerous natural and anthropogenic forces. Natural factors influencing erosion include precipitation, soil composition, slope length, and slope gradient. Land use is an anthropogenic component shaped by diverse human activities. The calculation of erosion within a watershed is significantly influenced by this element. This study aimed to examine land use alterations in the Cielunca catchment area, the erosion rate resulting from these land use changes, and the dynamics of erosion classification changes in the Cieluenca catchment area from 2004 to 2014. The study's results indicated a variation in the CP value from 0.5 to 0.6, signifying a transformation in land use within the catchment area of the Situ Cileunca. Erosion at a rate in the year 2004 is 325,408 t/ha/y (heavy erosion) and 2014 is 474,832 t/ha/y (heavy erosion). The erosion rate increased 46% from 2004 until 2014.
