                         com maior cobertura por mata ciliar, os coeficientes apontaram 
                         para maior regulariza{\c{c}}{\~a}o da vaz{\~a}o, por{\'e}m

                         {\'a}reas de lavoura foi atenuado pela {\'a}rea de mata na bacia

                         menor. ABSTRACT: Anthropogenic actions determine surface 
                         conditions and alter the proportions of land use and management in 
                         river basins. The use of coefficients that consider 
                         hydrosedimentological variables to evaluate man-environment 
                         interaction can be the effective way of quantifying the impacts of 
                         human action in the environment. The objective of this work was to 
                         evaluate the surface conditions provided by man-environment 
                         interaction through the regularization of flow and energy 
                         dissipation in two small river basins in areas of agrarian reform 
                         settlements (different forms of protection of riparian areas) in 
                         Rio Grande do Sul. In the small basin with greater coverage by 
                         riparian forest, the coefficients pointed to a greater 
                         regularization of the flow, but less dissipation of erosive 
                         energy. The degradation of the lower strata of the forest (free 
                         access to the cattle) compromises the capacity of retention of 
                         sediment compared to another small basin, whose regions near the 
                         watercourses predominate wetlands. The surface runoff generated in 
                         the cropping areas was attenuated by the forest area in the larger 
                         basin and enhanced by the humid areas in the lower basin.",
