    Water Jets can be used for shallow water, but you will have to figure out how the inlet stays clear from plants and stuff

    water jets were made for boats to travel over shallow water and over sand banks and logs and rocks !!:eek:

    Since 1954 at least. http://en.wikipedia.org/wiki/Bill_Hamilton_(engineer)

    "I do not claim to have invented marine jet propulsion. The honour belongs to a gentleman named Archimedes, who lived some years ago."

    "He investigated the American Hanley Hydro-Jet, a model which drew in water and fired it out through a steerable nozzle underneath the boat. Even when further adapted it did not work well. An employee suggested to have the nozzle just above the waterline."

    During the time the jet was being discovered i was just a kid with bare feet and short pants and we lived close to a river .
    I was priviledged to have ridden in one of the very first jet boats . It was plywood hull a ford mercury flat head vee 8 and a hamilton jet the boat was owned by mr Bill Dippy who in later years was to be come one of the top jet boat driver in the whole of new zealand , we went up the whakatane in just 4 inchs of water and turned and came back down and nosed up onto the bank so all us kids could get out . yes about 1954 !!:p i have a couple of picture that my mum took but could take some finding !!:D

    Sorry Kapil, I don't know a lot about water jets other than they are expensive and can be problematic.

    I'd go with an airboat if it's feasible for you.

    I've been to india, and i highly recomended waterjet, since the river has a plenty of sand banks, logs, plastic bags, and rocks with wildly varied depth. But still, not every river in india is the same, so you must be more specific in your requirement
