The International Network for Alpine Research Catchment Hydrology (INARCH)

Welcome to the website of INARCH, a cross-cut project of the GEWEX Hydroclimatology Panel to better understand alpine cold regions hydrological processes, improve their prediction, and find consistent measurement strategies.

2025 will be a momentous year for the network, with the start of the International Year of Glaciers' Preservation, the UN Decade of Action for the Cryospheric Sciences, completion of our COPE initiative, sessions at major conferences, our upcoming Fall workshop, and special issues of Hydrological Processes and Earth System Science Data.  Find information on all of these below.
