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
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

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
India’s 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
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
River Basins Modeled
Percent change in mean annual water balance for Control and GHG climate scenarios

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

Conclusions
Integrated water resource development and management requires a common framework
Creation of sharable information is essential for sustainable use of water resources and associated development and adaptation for climate change impacts
