Photos of Erosion Measuring Devices

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.
