    Drainage density = the total length of all the streams in the drainage basin divided by the total area of the drainage basin

    That's great, but what would be the practical method for working this out at field level?

    Sorry I don't have practicals as a part of the board I follow for A-level geography so can't help with that. However if you know the length and area of the places just simple add up the lengths and divide it by the area sorry couldn't be of much help. Hopefully someone else will see and be able to help you better!

    Using maps is probably the way to go. You can measure the length of all the tributaries and the main channel, and find the area of the drainage basin by finding the area encompassed by the watershed (which you'll be able to pinpoint by following the contour lines).

    I can't really think of another method.
