Erosión hídrica en la unidad hidrográfica del río Ambato, en un escenario de cambio climático, mediante el modelo usle/rusle.

The present reseach work deals with water erosion in the hydrographic unit of the Ambato river in which it was necessary to carry out an exhaustive study of all the factors inherent to the universal equation of the USLE/RUSLE soil losses. The factors studied are: Erosivity (R) erodability (K), length and degree of slope (LS), vegetation cover and land use (C), vegetation management programs (P) and finally as final result the soil loss factor (A). The temporal space studies were carried out with the support of the ArcGis 10.1 Geographic Information Systems computer tool for the application of spatial interpolations and multiplication of the proposed equation, the data studied and treated are precipitation from the year 1989 – 2014, edaphological 2014 – 2015 and vegetation, cover and land use 1990, 2000 and 2014. Results of potential losses of water erosion were obtained for 1990, the following ranges: None or slight represents 52.22% of the land surface, moderate 38.92% of the land surface, high 8.67% surface area and erosion very high 0,19%. The results for the year 2000 are as follows: None or light represented 49.29% of the land surface, moderate represented 41.41% of the land area, high represented 9.10% of the land area and very high erosion represents 0.20%. The results for the year 2014 are as follows: None or light represented 65.51% of the land area, moderate represented 24.88% of the land area, high represented 9.21% of the land area and very high erosion with 0,40% of the land surface located in streams near the rivers in the hydrographic unit of the Ambato river.
