Respectiive<br />

avail lable so thatt<br />

As far aas<br />

the groundwater<br />

work is<br />

concerned,<br />

model set up for Chammbal<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 />

held recently<br />

to finnalize<br />

of the Gannga<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 />

Following tthe<br />

main stem,<br />

the geommorphic<br />

map pping of majoor<br />

is also near r completionn<br />

and<br />

the group is finaalizing<br />

the river<br />

the tributar ries as well. The group is<br />

also involv ved in compuuting<br />
