The Haw River is the main sediment source to the lake, and bottom sediments are potential major contributors to nutrients in the lake.

Key Questions

  • What happens to sediments that enter Jordan Lake?
    • Where do they go?
    • How do they move throughout the year?


  • Sediment dynamics is highly variable but may be predictable if we use finding from our study with those from Rick Luettich and Harvey Seim.
Research Team Final Report

Brent McKee | UNC-Chapel Hill

Brent McKee’s overarching research focus is on land-ocean interactions and global change. He is interested in the role of Major Rivers (Amazon, Changjiang, Huanghe, Orinoco, Danube, Columbia, Mississippi) in global biogeochemical cycles and global change. Rivers are the primary interface between continental and oceanic environments and play a critical role in global cycles such as carbon. His recent research includes: transformation and fate of terrestrial materials (carbon, nutrients, trace elements) within river systems and in adjacent coastal margins; the role of tidal freshwater zones within rivers in controlling the flux of riverine materials to the ocean; the use of naturally-occurring radioisotopes to determine the rates and pathways for biogeochemical processes; diagenetic sedimentary processes in coastal environments; determination of weathering rates within river basins using uranium isotope tracers.
