| Abstract | MODIS/TERRA was used to monitor the snowpack dynamics in the Waitaki catchment, New Zealand, from 2000 to 2007. Daily meteorological data (i.e., temperature and precipitation) and frequent observations of the snowpack were used with the Snowmelt Runoff Model (SRM) to simulate the daily discharge of the Ohau, Pukaki, and Tekapo catchments. The results obtained over these seven years brought considerable improvements in terms of modelling performances compared to previous efforts conducted in the region. It shed new light about the relative contribution of snowmelt to the discharge. The simulations also suggest that the severe drought of 2005 was largely mitigated by ice melt from glaciers in the Pukaki basin. A contribution of glacier melt much larger than normal is believed to have sustained the discharge to within 17% of the mean annual flow, although the precipitation was reduced by 34%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
