Walker Branch Watershed: site description and research scope

PDF Version Also Available for Download.

Description

Walker Branch Watershed is located on the Oak Ridge Reservation in the Ridge and Valley section of Tennessee. The watershed (97 ha consisting of 2 subwatersheds) is underlain by Knox Dolomite; soils formed over the dolomitic substrate are deep, well-drained Typic Paleudults. The watershed is forested. The overstory is predominantly oak-hickory with lesser amounts of pine and mesic hardwoods. The Walker Branch Watershed Project was initiated in 1967 to: relate the productivity and water quality of the stream to the productivity and nutrient balance of the adjacent terrestrial ecosystem; relate the net loss of nutrient elements to the rate of ... continued below

Description

Walker Branch Watershed is located on the Oak Ridge Reservation in the Ridge and Valley section of Tennessee. The watershed (97 ha consisting of 2 subwatersheds) is underlain by Knox Dolomite; soils formed over the dolomitic substrate are deep, well-drained Typic Paleudults. The watershed is forested. The overstory is predominantly oak-hickory with lesser amounts of pine and mesic hardwoods. The Walker Branch Watershed Project was initiated in 1967 to: relate the productivity and water quality of the stream to the productivity and nutrient balance of the adjacent terrestrial ecosystem; relate the net loss of nutrient elements to the rate of nutrient cycling; define the relationship between the hydrologic cycle and nutrient flux; provide benchmark information on natural terrestrial-aquatic ecosystems for comparison with man-modified situations; and to enable the measurement of environmental degradation caused by man's cultural practices. Research has been completed or is on-going in several distinct, but related, areas: ecosystem analysis of essential element dynamics (N, P, K, Ca, Mg and C), atmospheric and hydrologic input-output processes, trace element biogeochemistry (e.g., Cd, Pb, Zn) and sulfur. Research objectives have been approached by analysis of the role of important biological and physical processes, and the development of mathematical models.
