In the Texcoco river basin it has been elaborated an integral management of basins with the intention of rehabilitation of the eroded zone, water runoff control and sediment yield, through the construction of bench terraces, silt-controlled dams and reforestation. The objectives were to analyze variations in vegetation and soil use, to evaluate the impact of rehabilitation works on soils and hydrological variables, before and after management. A statistical analysis was performed using yearly data. Results Indicate a significant reduction of variables under analysis in a magnitude very close to 80% while the t-Student test showed significant difference between means of variables.
