Project description
Snow conditions in high-latitudes are expected to change due to climate change, which will have significant impacts on northern environment. Still it’s not well understood how snowmelt water is stored and released in northern landscape, even though the snowmelt period is important in water management influencing both water quantity (floods, water availability) and quality (sediments, nutrients). This work will advance snowmelt hydrology with a novel combination of latest stable water isotope tracer and numerical modelling techniques. Project will measure water isotope composition in snowfall, snowpack, snowmelt, soil, groundwater and eventually streamflow in an unforeseen temporal and spatial resolution. Work will be focused at Pallas, “supersite” for environmental science in Finland, and expanded with strong international collaborations. The comprehensive isotope data will inform numerical model development, and the combination will lead to significant advances in snowmelt hydrology.
