| description | The purpose of this study was the
estimation of current and potential water
erosion rates in Castellon Province (Spain)
using RUSLE3D (Revised Universal Soil
Loss Equation-3D) model with Geographical
Information System (GIS) support. RUSLE3D
uses a new methodology for topographic
factor estimation (LS factor) based on the
impact of flow convergence allowing better
assessment of sediment distribution detached
by water erosion. In RUSLE3D equation, the
effect that vegetation cover has on soil erosion
rate is reflected by the C factor. Potential
erosion indicates soil erosion rate without
considering C factor in RUSLE3D equation.
The results showed that 57% of estimated
current erosion does not exceed 10 t/ha.year
(low erosion). In the case of potential erosion
rates, 5% of the area of Castellon Province
does not exceed 10 t/ha.year but 55% exceed
200 t/ha.year. Based on these results, the
current vegetation cover of Castellon Province
is adequate but needs to be conserved to avoid
an increase in the current soil erosion rates as
shown by potential erosion rates. |

El objetivo de este estudio fue la estimación de las tasas de erosión hídrica, actual y potencial, en la Provincia de Castellón (España) utilizando el modelo RUSLE3D (Revised Universal Soil Loss Equation-3D), y el apoyo de Sistemas de Información Geográfica (SIG). RUSLE3D utiliza una nueva metodología para la estimación del factor topográfico (factor LS) basado en el impacto de la convergencia del flujo lo cual permite una mejor evaluación del movimiento de sedimentos. En RUSLE3D, el efecto de la cobertura vegetal sobre la tasa de erosión lo refleja el factor C. La erosión potencial representa la tasa de erosión sin considerar el factor C en RUSLE3D. Los resultados mostraron que el 57% de la erosión actual no supera las 10 t/ha.año (erosión baja). En el caso de la erosión potencial, el 5% del área de la provincia es inferior a 10 t/ha.año, pero un 55% supera las 200 t/ha.año (erosión muy alta). En base a estos resultados, la actual cobertura vegetal de la provincia de Castellón es adecuada, pero tiene que ser conservada y protegida para evitar un aumento en las actuales tasas de erosión, tal como lo indican los valores de erosión potencial.
