An appropriate forest management is essential to ensure a balance between hydrological parameters (runoff, discharges, groundwater, infiltration, retention, etc.) taking into account that, they are directly influenced by the structure and quality of forest. In this study was analyzed the Tărlung river basin, located in a mountainous area in the center of Romania. Inside the river basin is Săcele Reservoir which represents the main source of water for Braşov Metropolitan Area (providing about 90% of the water demand). In order to estimate the availability of water in the river basin for the following decades, an integrated hydrological model (SWAT) was used in the context of two regional climatic scenarios and taking into account 9 different combinations between land uses and forest management scenarios. The available water in the river basin along with the urban dynamics (manifested by the dynamics of water consumption for the needs of the population and other users) will allow us to establish the water supply from additional sources (groundwater pumping) and, implicitly, the extra energy consumption for processing it. Additional power consumption for drilling water is reflected in additional GHG emissions.
