INARCH is a global collaborative research initiative in mountain hydrology to better understand hydrological processes in alpine cold regions and to improve prediction and find consistent measurement strategies for these processes. ** INARCH is still funded and is still active as of 2021! ** The following research questions relating to alpine hydrology and related snow and glacier studies and hydrometeorology are posed by INARCH: - How different are the measurement standards and the standards for field sampling and do we expect distinctive differences in model results and hydrological predictability because of the sampling schemes, data quality and data quantity? - How do the predictability, uncertainty and sensitivity of catchment energy and water exchange vary with changing atmospheric dynamics in various high mountain regions of the Earth? - What improvements to high mountain energy and water exchange predictability are possible through improved physics in land surface hydrological models, improved downscaling of atmospheric models in complex terrain, and improved approaches to data collection and assimilation of both in-situ and remotely sensed data? - Do the existent model routines have a global validity, are they transferable and are they meaningful in different mountain environments? - How do transient changes in perennial snowpacks, glaciers, ground frost, soil stability, and vegetation impact models of water and energy cycling in high mountain catchments?
