The aim of this article is to demonstrate the afforestation role in maximum surface runoff. In this way, it was made a comparison of simulated flows in the current conditions of afforestation and the simulated flows in conditions of applying both afforestation and deforestation scenarios in Valea Rece catchment. Through HEC-HMS 4.1 hydrologic modeling software, using the method of unit hydrograph SCS Curve Number, were simulated flow of the river Valea Rece closing section of the basin, where precipitation amounts of 30,50,80,120 mm fallen in intervals of 1.3 to 6 hours on a soil with varying degrees of moisture: dry soil, average soil moisture and high humidity. This was done for the current degree of afforestation basin, for the results from a possible afforestation that would increase the afforestation degree to 80%, and for a possible deforestation that would lead to a degree of afforestation 15 %.
