HGS RESEARCH HIGHLIGHT – Simulating the recession dynamics of Arctic catchments in the context of a thawing permafrost

In a recent study, researchers have made significant strides in understanding how climate warming is altering the Arctic's hydrological dynamics. The study delves into the complex relationship between permafrost thaw and groundwater flow. Traditionally, Arctic hydrology has been conceptualized as a local system, confined by the frozen ground. However, as the climate warms, permafrost begins to thaw, transitioning this system into a more interconnected network of regional aquifers. This transformation is crucial, as it alters the fundamental dynamics of water movement and storage in the Arctic.

HGS RESEARCH HIGHLIGHT – Evaluation of baseflow separation methods with real and synthetic streamflow data from a watershed

Stream baseflow is inherently difficult to accurately estimate given the varied sources contributing to baseflow, it’s spatial variability, and the logistical difficulties in making physical baseflow measurements. Thanks to the fully integrated nature of HydroGeoSphere, and the fact that HGS was created with a strong emphasis on physics, HydroGeoSphere represents a very powerful tool for baseflow estimation, especially in lightly studies watersheds!

HGS RESEARCH HIGHLIGHT – Sources of surface water in space and time: Identification of delivery processes and geographical sources with hydraulic mixing-cell modeling

The paper highlighted this week presents a very interesting post-processing method for HydroGeoSphere models. The results of the HGS model were used as input into the hydraulic mixing-cell (HMC) approach which enables tracking and delineation of the mixing of predefined initial water sources at any location and at any time based on information from the hydraulic flow solution
