For water on the land I have not done that, The main things i would look at are-
Water sirplus and defasit(unlikely)
factors effecting discharge(very likely)
rivers flooding in medc and ledc (cumbria and india)(likely)
dams(three gorges dam)(very likely)
ob bow lakes (very likely)
gorges(un likely)
flood plains(unlikely)
leeves(unlikely)
what is flooding (likely)
erosion(likely)
how a river carries its load(likely)
how a river changes down stream(likely)
hard and soft engineering strategies(unlikey)
hydrographs(very likely)
I think that this is all you need to know. Hope this helps.
Remember to revise everything they are just my predictions!
