1. Geomorphology, Fall 2006 25 cm DEM view of piece of landscape

2. Geomorphology, Fall 2006 Drainage network: drainage area greater than 10 m 2

3. Geomorphology, Fall 2006 Hillslopes: drainage area < 10 m 2

4. Geomorphology, Fall 2006 Partitioned view of drainage network and hillslopes at 10 m 2 threshold --very different processes dominate in the two different domains

5. Geomorphology, Fall 2006 Drainage basin: boundary of contributing area = 0 for given outlet

6. Geomorphology, Fall 2006 Drainage network: “skeleton” of the landscape --KXW

7. Geomorphology, Fall 2006 Hillslopes: “flesh” of the landscape --KXW
