The developed hydrological model provides the means to estimate and monitor cryospheric melt and its impact on streamflow at a daily resolution. This tool is especially valuable in a region that is marked by extreme inter- and intra-annual variability in streamflow, influenced by the duration and intensity of precipitation events, temperature change, and annual snow-pack levels. Across the Himalayan region, population centers are directly impacted by abrupt and extreme climate change events that affect hydrological flow, including the occurrence of GLOF (Glacier Lake Outburst Flood) events. Therefore, there is a critical need for climate monitoring tools across the region that can be used at the local institutional level. We developed the GEOStreamFlowMonitoring tool that can be implemented by local institutions to examine climate variability and prepare for emergency hazards. In this talk we will outline our project and discuss the development of our hydrological model, international collaborations, and implementation across various social, political, and science sectors.
