Exploring Permafrost Hydrology Dynamics

Hydrology is a critical area of study that particularly concerns the dynamics and ecological impacts on permafrost environments caused by groundwater and surface runoff. These components play a significant role in regulating the thermal state of permafrost, influencing sediment transport and ecological stability. The active hydrologic activity during the ablation season, driven by thawing ground and melting of snow and ice, underscores the complexity of these environments. Recent observations have highlighted rapid changes such as the accelerated retreat of glaciers and the increasing importance of permafrost as a major water source in these evolving landscapes. Despite its significance, the role of permafrost in the hydrological cycle remains poorly understood, revealing a substantive gap in current scientific knowledge.

This Research Topic aims to further study and understand the intricate interactions between surface runoff, groundwater, and both the thawing of the active layer and deeper permafrost. Understanding these relationships is crucial for predicting future hydrological and ecological dynamics. We intend to enhance the existing body of knowledge through cutting-edge experimental and modeling studies that examine these interactions.

To gather further insights into the defined boundaries of permafrost hydrology, we welcome articles addressing, but not limited to, the following themes:

- Spatio-temporal variability of soil moisture

- Interactions between glacier meltwater and permafrost

- Sediment transport in polar streams

- Effect of streams on the variability of active layer thickness

Through this Research Topic, we hope to address key questions and test hypotheses related to the multifaceted role of permafrost, offering new perspectives and understanding of these critical systems.
