The trends analysis of hydroclimatic variables (rainfall, temperature, streamflow) in headwater catchments provides basic scientific criteria necessary for water resource planning and management. However, relatively few studies have been carried out in these relatively near-natural systems, i.e. with little or no alteration by humans. In this context, the overall aim of the present study is to characterize the recent trend of stream discharge in a headwater catchment of the Mero Basin (NW Spain). The results showed no significant decrease in annual stream discharge. However, a significant decrease in summer and autumn stream discharge and an increase in the duration and severity of low flow was detected. In this study, a parallelism between hydrological processes and rainfall was not appreciated. So, the trends observed for streamflow are probably related to upward trend in temperature, by enhancing evapotranspiration.
