Following a successful visit to Andhra Pradesh (see post below), Johan Grijsen,
representing the
World Bank, together with Narayan Bhat of the TAMC, visited Tamil
Nadu to assess
the progress with the DSS.
The hydrological
conditions in Tamil Nadu are from an overall
perspective rather unique and different from other States, in
the sense that
most of the 17 Basins in the state feature thousands of
traditional tank
systems, ranging from very small to very large tanks. These
tanks along with
groundwater exploitation form the major source of water for
domestic and
industrial water supply as well as minor irrigation. Tanks also
play a major
role in the recharge of groundwater (3 months per year). Since
the groundwater
component of the MIKE BASIN model has limited options for an
adequate modeling
of infiltration and recharge of groundwater, Tamil Nadu deemed it
necessary to
introduce the MIKE SHE model for the DSS to accommodate the modeling of groundwater processes.

So far Tamil Nadu is running three pilot DSS
systems for the
Vaipar, Tamiraparani and Agniar Basins. In the coming weeks some
preliminary
results of these projects should become available.
Tamil Nadu has an active Hydrological Data Users Group so everybody is very keen to learn about these first results of the pilot DSS.

Realising the importance of spreading information the departments make sure that each Hydrology Data Users Group meeting is covered by the press (see here).
