    Goel, Malti (National Institute of Hydrology, 2007)
    The Himalayan-Karakoram Mountain chain forms an important mountain region between the Indian ocean basin and the highland of Tibet. The summer monsoon rainfall and the strong high pressure field called 'Tibetan high' have ...
  • 7-Effect of Global Warming on the Himalayan Cryosphere. 
    Kulkarni, A. V. (National Institute of Hydrology, 2007)
    In the Himalayas, a large area is covered by glaciers and seasonal snow and changes in its extent can influence availability of water in the Himalayan Rivers. This paper discusses changes in glacial extent, glacial mass ...
  • 8-Water Resources Potential of Himalayas and Possible Impact of Climate . 
    Singh, P.; Arora, Manohar (National Institute of Hydrology, 2007)
    The concentration of several greenhouse gases has increased over time. Human activity increases the greenhouse gases effect primarily through release of carbon dioxide, but human influences on other greenhouse gases is ...
  • 9-Impact of Satellite Derived Land Surface Data in Regional Climate Simulations Over India. 
    Pal, P. K.; Rakesh, V.; Singh, R.; Joshi, P. C. (National Institute of Hydrology, 2007)
    It is well established that mesoscale models have a pronounced skill in reproducing regional climate as compared to global models. The objective of this study is to assess the impact of improved land surface representation ...
  • 10-Water Resources in India and Impact of Climate Change. 
    Mall, R. K.; Bhatla, R.; Pandey, S. N. (National Institute of Hydrology, 2007)
    There is now clear evidence for an observed change in global surface temperature, rainfall, evaporation and extreme events since the start of 20th century. In recent times, several studies around the globe have shown that ...
  • 11-High Resolution Monsoon Records from Land and Ocean - What Have We Learnt During the Last Decade. 
    Singh, A. K.; Yadava, M. G.; Ramesh, R. (National Institute of Hydrology, 2007)
    Impact of global climate change on the future water resources of India is intimately coupled with the variation of monsoon wind and monsoon rainfall. In this paper, the differences in paleo records from different areas ...

  • 3-Moderation of Floods and Mitigation of Droughts through Integrated Watershed Management . 
    Sharda, V. N.; Ojasvi, P. R. (National Institute of Hydrology, 2006)
    Frequent occurrence of floods and droughts in the country is a cause of serious concern for the planners, policy makers, hydrologists, conservationists and environmentalists. Spatial and temporal distribution of rainfall ...
  • 4-Agricultural Drought Management in Rainfed Areas of Semi-Arid Regions of South India. 
    Mishra, P. K.; Adhikari, R. N.; Patil, S. L. (National Institute of Hydrology, 2006)
    In the semi-arid regions of South India, droughts are more common and occur either due to failure of South-West or North-East monsoon. Drought impacts on agriculture are managed by taking appropriate preventive measures ...
  • 5-Drought Forecasting Using Standardized Precipitation Index. 
    Desai, V. R.; Mishra, A. K. (National Institute of Hydrology, 2006)
