Characterizing stream intermittency using water sensors and time-lapse cameras and biogeochemical implications in Buck Creek, KS (USA)
Intermittent streams are terrestrial aquatic interfaces; ecosystems that cyclically switch between phases of saturation across space and time. Cyclic changes between wet and dry stream conditions in the hyporheic zones of intermittent streams may impact biogeochemical processes. Here, we evaluate hydro-biogeochemical dynamics in two intermittent headwaters of a tributary to the Kansas River watershed, linking the presence and absence of water flow using temperature and electrical resistivity sensors with in-stream nutrient chemistry (NO3-, SRP). Additionally, we tested trail cameras as a method for capturing continuous stage measurements. Understanding temporal and spatial driven surface water availability in intermittent streams will help to predict patterns of expansion and contraction. We explore the variability of surface water in intermittent streams and the complex hydrology and biogeochemical dynamics. It is especially important to link changes in the availability of water in intermittent streams to biogeochemical reactions since the spatial and temporal extent of the dry phase of intermittent streams may change as a result of climate change.
