National Institute of Hydrology has been carrying out hydrological studies since 1999 on Gangotri Glacier, which is one of the biggest glaciers of Himalayas. In the Snow and Glacier laboratory analysis and modelling of Snow and Glacier melt runoff, based on the observations taken at the Gangotri site of the meteorological observatory with AWS established at Gangotri Glacier at an altitude of 3600 m are carried out. A stream flow discharge site is also being maintained at that location. A conceptual model for simulating snow and glacier melt runoff has been developed at the institute and is being applied for snow and glacier modelling at this lab. Since most of these facilities are at harsh location and inaccessible sites the details of studies are exhibated for the visitors. For local common people a weather display unit is installed over the main building. It displays the instantaneous temperature and relative humidity. The weather parameters observed on previous day are also displayed. The control unit and operation facility is being maintained in the laboratory.
