This article explores the use of time-lapse photography to study hydrological processes in a headwater creek. The authors emphasize the importance of new observational field data in advancing scientific understanding and propose the undercranking filming technique as a way to capture a wider spatial and temporal context of catchment characteristics and functioning. The study focuses on the Weierbach experimental catchment and utilizes a wildlife monitoring camera to record images every 15 minutes over a period of 20 months. The resulting time-lapse video provides insights into the seasonal pulse of the creek and the interplay between various hydrological processes. The article discusses the findings of extensive field monitoring campaigns in the Weierbach catchment, highlighting the occurrence of double-peak hydrographs during wet conditions, the role of leaf abscission and litter degradation in nutrient availability, and the influence of freeze-thaw cycles on sediment transport. The use of time-lapse videos and high-resolution environmental sensing programs offers valuable insights into the complex interplay of biotic and abiotic factors in the catchment. The article emphasizes the need for further research and modeling to fully understand the eco-hydrological functioning of the Weierbach catchment and its response to climate change.
