Hydroloogical<br />

issues aare<br />
causing delay in pprogress<br />
for hydrologica al and hydrraulic<br />
modeling.<br />
Respectiive<br />
groups in<br />
all IITs aree<br />
eagerly wa aiting for the<br />
data to become<br />
avail lable so thatt<br />
the<br />
modeling<br />
work can be completeed.<br />
As far aas<br />
the groundwater<br />
moddeling<br />
work is<br />
concerned,<br />
model set up for Chammbal<br />
river bas sin, a tributaary<br />
of<br />
Yamuna<br />

The DEEM<br />

that are being<br />
obtaineed<br />
through th he primary survey.<br />
Thesee<br />
data are be eing used to start<br />
gettingg<br />
the first cuut<br />

will be uupdated<br />
with h the more refined data<br />

(FGMM):<br />
The FGM Group is involved in mapping aand<br />
characteerizing<br />
the Ganga G River aand<br />
her majoor<br />
tributaries s for geomorphic<br />
asseessment<br />
of river<br />
conditioon.<br />
Data gennerated<br />
fromm<br />
this group will form ann<br />
important ccomponent<br />
in developinng<br />
an<br />
ecossystem‐based<br />
managemment<br />
of the Ganga River.<br />
Till now, the group hhas<br />
prepareed<br />
two reports<br />
titled, AActive<br />
Flooodplain<br />
Mappping‐<br />
defining<br />
the ‘river sspace’<br />
and DDelineation<br />
of f Valley Marrgin<br />
and Geomorphic<br />
Mapping<br />
of Chaannel<br />
Belt and Active Floodplain oof<br />
the Gangaa<br />
River. Twoo<br />
group mee etings cum wworkshops<br />
wwere<br />
held recently<br />
to finnalize<br />
geommorphic<br />
chaaracterizationn<br />
of the Gannga<br />
River annd<br />
to define e templates for the majoor<br />
attributes s of River Sttyles.<br />
Thesse<br />
templatess<br />
along with the River Styyle<br />
differenttiation<br />
will fu urther be useed<br />
to assess the geomorphic<br />
conditioon<br />
of<br />
the Ganga River.<br />
Following tthe<br />
main stem,<br />
the geommorphic<br />
map pping of majoor<br />
tributariess<br />
is also near r completionn<br />
and<br />
the group is finaalizing<br />
the river<br />
style fraamework<br />
forr<br />
the tributar ries as well. The group is<br />
also involv ved in compuuting<br />
stream<br />
power ddistribution<br />
inn<br />
the Gangaa<br />
basin. This will help to better undeerstand<br />
