Topo Recompute

Threshold Parameter - The value will be used to identify pixels from the flowaccumulation grid which are supposed to be streams. Default value is 100. If stream network and subsequent derived terrain parameters need to be adjusted please used topowshd.

Allows for the re-computation of the stream-based terrain parameters of the topo script. Usually, the topo script is computed once, however on closer observation we find that the choosen stream flow threshold did not delineate the watersheds appropiate. Therefore, to recompute the TP parameters based on this threshold, use this routine.
