Help about Container ship...

I am recently having my class project on Container ship. It is an internal route (Bangladesh) vessel having highest length(oa) 83 m. It's capacity is 150 TEU. I want to have some long term help from any one to present the job precisely.

 

what is depth of waterways and do you have a good map(chart) of Bangladesh navigable rivers and canals?

are we talking about a container ship pulling into nice container crane port, or a ship with ability to load and unload containers onto "lighters" or docks on its own?, or even unload them onto "the hard" at low tide while beached?

Personally, I think a self loading/unloading small container ship would be kinda cool.

 

There is a constrain of 4 m draft.
