How much water flows where? Use this algorithm to calculate the upslope area of each cell in a digital elevation model.

Algorithm specifications:
- multiple flow direction
- single flow direction
- routes across flats
- calculates deterministic, randomized and random flow
- allows you to specify a weighting exponent that governs the relation flow direction - slope
- handles edge effects

update of the description

an option was added to control flow behavior at grid edges

included single flowdirection and the exponent for flow direction weighting to address the problems encountered by Liam.
