Why do I want to make model of Ganga?

Because I want to explore the route map of ganga.

What is a route map?

The way Ganga is flowing - the different form it takes from its source to where the river meets the sea.

How will I make it?

I don't know!

I will Make mountains of Clay

and then i will make a path for the river to flow - from the top to the end.

I will put ice at the top and then the ice will melt and flow down - then the two river will meet and form ganga.

then it will flow into the plains. I will show grass, trees, greenery, etc.

The ganga will in the end form delta and meet the sea.

What about the cities?

That i have to research.

Some of the cities which i can show are Devprayag, Haridwar, Allahabad (since there iyamuna meets the ganga), Varanasi, kashi, sunderbans...

For these citiies i can make  

Har-ki-podi, sangam in allahabad, Ghats & Temples at Varanasi & Kashi etc

What all material you can experiment?

Clay, Plaseer of Paris, News paper, papier mache, old al. foil, stones, sand, -more I will think
