Groundwater-surface water (GW-SW) interactions play an important role in northern catchments, but their dynamics and water, carbon, nutrient balances are still poorly understood. In this case study, we (1) explored groundwater-surface a sub-arctic headwater watershed Pallaslompolo, Finnish Lapland. (2) We compared fully-integrated physically-based simulations of the groundwater surface with unique spatially distributed field datasets drone-derived thermal infrared imaging (TIR) peat pore...
Abstract Subarctic ecohydrological processes are changing rapidly, but detailed and integrated investigations not as widespread necessary. We introduce an research catchment site (Pallas) for atmosphere, ecosystems, ecohydrology studies in subarctic conditions Finland that can be used a new set of comparative investigations. The Pallas provides unique observational data high‐intensity field measurement datasets over long periods. infrastructure atmosphere‐ to landscape‐scale ecosystem...
Abstract Fully integrated physically based hydrological modeling is an essential method for increasing understanding of groundwater‐surface water (GW‐SW) interactions in peatlands and predicting anthropogenic impacts on these unique ecosystems. Modeling studies represent peat soil a simplistic manner, as homogeneous layer uniform thickness, but field measurements consistently show pronounced spatial variability peatlands. This study evaluated uncertainty groundwater levels exfiltration...

Abstract. Peatlands are the most dense terrestrial carbon storage and recent studies have shown that northern peatlands continued to expand new areas this day. However, depending on vegetation hydrological regime in newly initiated areas, climate forcing may vary. If these develop as wet, fen-type with high methane emissions they would initially a warming effect climate. On other hand, if development starts dry bog-type peatlands, peatland likely act strong sink from early on. although some...
<p>Seasonally frozen ground (SFG) occurs on ~25% of the Northern Hemisphere’s land surface, and influence SFG water, energy, solute fluxes is important in cold climate regions.  The hydrological role permafrost now being actively researched, but has been receiving less attention. Intuitively, water movement blocked by ice forming soil pores that were open to flow prior freezing. However, it shown insignificant some cases, with remaining permeable even...
<p>Particularly in the Nordic region, water excess and shortage (drought) are becoming more frequent phenomena that challenge development of agriculture crop production. Identification appropriate management strategies is essential (i) to ensure sustainable resources for production functioning healthy ecosystems; (ii) improve resilience hydrological extremes. Integrated models offer potential through understanding forecasting systems under anthropogenic climatic influences,...
