Cold regions involve hydrological processes that are not often addressed appropriately in models. The Regions Hydrological Modelling platform (CRHM) was initially developed 1998 to assemble and explore the understanding from a series of research basins spanning Canada international cold regions. basin response simulated flexible, modular, object-oriented, multiphysics platform. CRHM allows for multiple representations forcing data interpolation extrapolation, model spatial physical process...
Abstract Wildfire occurrence and severity is predicted to increase in the upcoming decades with severe negative impacts on human societies. The of upwind wildfire activity glacier melt, a critical source freshwater for downstream environments, were investigated through analysis field remote sensing observations modeling experiments 2015–2020 melt seasons at well‐instrumented Athabasca Glacier Canadian Rockies. Upwind influenced surface both decrease albedo from deposition soot impact smoke...
Spatially distributed surface temperature is an important, yet difficult to observe, variable for physical glacier melt models. We utilize ground-based thermal infrared imagery obtain spatially data alpine glaciers. The images are used investigate microscale processes at the surface, such as effect of cover type and gradient margins on glacier's dynamics. Infrared were collected Cuchillacocha Glacier, Cordillera Blanca, Peru, 23–25 June 2014. corrected based ground truth points local...
Abstract A myriad of downstream communities and industries rely on streams fed by both groundwater discharge glacier meltwater draining the Cordillera Blanca, Northern Peruvian Andes, which contains highest density glaciers in tropics. During dry season, approximately half region's proglacial comes from groundwater. However, because remote difficult access to region, there are few field methods that effective at reach scale identify spatial distribution discharge. An energy balance model,...
Abstract Peruvian glaciers are important contributors to dry season runoff for agriculture and hydropower, but they at risk of disappearing due climate change. We applied a physically based, energy balance melt model five on‐glacier sites within the Cordilleras Blanca Vilcanota. Net shortwave radiation dominates balance, despite this flux being higher in season, rates lower losses from net longwave latent heat flux. The sensible is relatively small contributor energy. At three wet snowpack...
Abstract Mountain glacierized headwaters are currently witnessing a transient shift in their hydrological and glaciological systems response to rapid climate change. To characterize these changes, robust understanding of the processes operating basin interactions is needed. Such an investigation was undertaken Peyto Glacier Research Basin, Canadian Rockies over 32 years (1988–2020). A distributed, physically based, uncalibrated glacier hydrology model developed using modular, object‐oriented...
Abstract Shifting precipitation patterns, a warming climate, changing snow dynamics and retreating glaciers are occurring simultaneously in glacierized mountain headwaters. To predict future hydrological behavior an exemplar basin, spatially distributed, physically based cold regions process model including on off‐glacier representations was applied to the Peyto Glacier Research Basin Canadian Rockies. The forced with bias‐corrected outputs from high‐resolution Weather Forecasting (WRF‐PGW)...
ABSTRACT Tropical glaciers constitute an important source of water for downstream populations. However, our understanding glacial melt processes is still limited. One observed process that has not yet been quantified tropical the enhanced caused by longwave emission transfer. Here, we use high-resolution surface temperatures obtained from thermal infrared imagery Cuchillacocha Glacier, in Cordillera Blanca, Peru June 2014 to calculate a margin flux. This flux, reaching glacier adjacent...

This paper presents hydrometeorological, glaciological and geospatial data from the Peyto Glacier Research Basin (PGRB) in Canadian Rockies. has been of interest to hydrological researchers since 1960s, when it was chosen as one five glacier basins Canada for study mass water balance during International Hydrological Decade (IHD, 1965–1974). Intensive studies observations continued after IHD, initial seasonal meteorological stations were discontinued, then restarted continuous late...
Glacier ecosystems are shrinking at an accelerating rate due to changes in climate, and increased darkening from allochthonous autochthonous carbon is leading light absorption, associated heat, microbial communities.
Both the mountain cryosphere -- comprising glaciers, snow, and permafrost groundwater play crucial roles in shaping hydrological cycle. However, their connectivity is not well understood. Understanding importance of sub-surface meltwater flowpaths role regions critical to untangle 1) fate cycle 2) sensitivity a changing supply due climate change. Here, we synthesize studies which investigated dynamics flow through aquifers. In general, snow-groundwater better described than...

Glacier melt is known to provide an important source of water streamflow in glacierized tropical regions, especially during the dry season. Groundwater also contributes a significant amount streamflow. However, linkage between two often unclear: How much groundwater originates from glacier melt? More broadly, how will and surface contributions change as glaciers retreat climate changes? We developed glacio-hydrological model Cold Region Hydrological Modelling platform explore complex...
While mountain groundwater in glacierized regions has gained increasing attention, comprehensive insights of glacier melt contributions to and their resurfacing patterns remain limited. Our study employs a cryosphere-surface hydrology model combination with numerical simulations estimate the water table variations across high-altitude Langshisha basin Langtang Himalaya (4094-6049 m). We evaluate surface water-groundwater interactions amidst current projected climatic conditions. Utilizing...
Abstract While mountain water faces threats posed by climate change, particularly in snow-dominated and glacierized systems, the role of groundwater sustaining streamflow these systems remains elusive. Changing headwaters, marked reduced snowpacks, retreating glaciers, shifting precipitation patterns, rising temperatures, pose a crucial question: what is resilience mountains, does play this resilience? This uncertain tropical high mountains where seasonality glacier melt govern generation. A...
