Objectives

• Analysis of spatio-temporal variability of
  precipitation over major river basins of India
• Study of past changes in water availability and
  their sensitivity to climate variability and
  land-use/land-cover changes
• Evaluation of regional climate model simulations
  of precipitation
• Study of past changes in water quality
• Development of future scenarios for water
  availability and quality under different climate
  change scenarios

  climatology of major river basins
  Spatio-temporal variability of precipitation
• Evaluation of HadRM2 simulations of monthly/daily
  precipitation over major river basins
• Case studies of past changes in water
  availability and quality in relation to climate
  and land-use/land-cover changes
• Hydrometeorological analysis of HadRM2
  simulations for major river basins
• Water availability scenarios for major river
  basins including the scenarios for the impacts of
  land use and cover

Rainfall Data

• Homogeneous monthly rainfall data set for 306
  stations (1871-2001)
• Daily rainfall data at 500-1000 raingauge
  stations during 1901-90 (variable network)

Identification of Target River Basins

• 66 notable river basins
• 3 large river basins identified Ganga, Godavari
  and Krishna
• Summer monsoon main source of water for all the
  three basins
