Erosion in the Rio Puerco: Geography and Processes
Scientists have constructed a small artificial wall to collect runoff
and sediment moving on a hillside during precipitation events. The
board at the bottom of the photo covers a collection trough; tubes
connect the trough to collection buckets that provide capacity for large
events (see next illustration).
Tubes from the collection trough (see prior illustration) carry excess
water and sediment to collection buckets, which are weighed after each
storm event in order to measure water and sediment production.
