2 Friday, February 07, Water resource development Shall always remain one of the preferred options to cater to vagaries on account of Inherent Spatial variability and Temporal variability of this resource And now the climate change impacts

3 Friday, February 07, Possible development options Surface water Interventions – different scales Big projects – Reservoir or runoff the river scheme Medium & Minor schemes Watershed level – check dams Ground water exploitation Shallow wells Deep tubewells

4 Friday, February 07, Implications of interventions Every intervention big or small has associated impact Integrated Watershed philosophy was the scientific option suggested to judiciously tackle possible implications Watershed being the natural system where water balance can be resolved and thereby impacts of the manmade interferences quantified

5 Indias National Communications to UNFCCC Coordinated by MoEF The first communication was made in 2004 It was a multidisciplinary effort Work on water Resources was entrusted to IIT Delhi Second National Communication has just started and IIT Delhi is again leading the Water Resources work

6 SWAT Model Components Features Physically based Distributed model Continuous time model (long term yield model) Uses readily available data Suitable for long term impact studies

7 River Basins Modeled

8 Percent change in mean annual water balance for Control and GHG climate scenarios

9 Himalayan River Systems: Ganga Basin

10 The major concern Evaluate the implications of climate change by incorporating the baseline Adaptation shall require enhanced level of interventions through line departments A common framework is required to provide an integrated information base Procedures for scenario generation and evaluation Friday, February 07,
