Event controls on intermittent streamflow in a temperate climate

Abstract. Intermittent streams represent a substantial part of the total stream network, and their occurrence is expected to increase due climate change. Thus, it high relevance provide detailed information on temporal spatial controls streamflow intermittency support management decisions. This study presents an event-based analysis responses in intermittent mesoscale catchment with temperate climate. Based responses, precipitation events were classified into flow or no-flow classes. Response like precipitation, soil moisture, temperature used as predictors random forest model identify temporally changing factors that explain at event scale. Soil moisture was most important predictor, but predictor importance varied geology catchment. Streamflow slate controlled by shallow deep layers, while marl primarily upper layer. catchments underlain both sandstone dependent whereas only pure depended characteristics. In all catchments, also temperature, which probably proxy for seasonal changes evapotranspiration indicator freezing conditions. Our findings underline using resolution data tailored definitions account fast between flow/no
