Investigating the future evolution of Norwegian glaciers and hydrological impacts: an integrated modelling approach (EVOGLAC project)
Abstract
Glaciers provide natural storage and regulation of water supply to rivers, which, in turn, contribute to water supply for domestic and industrial consumption, irrigation and hydropower, especially in Norway. There is a critical and pressing need to better understand the effects of climate change on glaciers, and the local-to-regional hydrological impacts these changes induce, in a holistic manner. However, the regional processes, mass balance and/or other glacial processes, are still poorly understood. Further, the impacts these changes have on water resources are typically investigated via a one-way chain of discrete models, which often have significant assumptions, missing feedbacks and mismatches in temporal and spatial resolution.
The "Investigating the future evolution of Norwegian glaciers and hydrological impacts: an integrated modelling approach (EVOGLAC) " project (2016-2019) is funded by Norwegian Research council, which aims to develop an integrated atmosphere-glacier-hydrological modelling system, test it on the present and apply it to future climate projections for a well-monitored Norwegian glacier complex. We conducted field campaigns from 2016 and build, tested and then will apply, a fully coupled atmosphere-glacier-hydrological modelling system over a well-monitored glacier complex in Norway (Hardangerjøkulen). The centerpiece of the project will be a multi-scale, very high-resolution, fully coupled, transient simulation for the middle of 21st century, which will be used to investigate the central hypotheses and compare against existing model-chain and statistical approaches to modelling glacier and hydroclimate responses to warming.- Publication:
