Research Project:
Determination of Sediment Sources in ARS Ceap Benchmark Watersheds
Location: Watershed Physical Processes Research Unit
Project Number: 6408-13000-018-21
Project Type:
Specific Cooperative Agreement
Start Date: Sep 22, 2006
End Date: Jun 30, 2009
Objective:
Increase knowledge of sediment erosion and transport by determining the sources of fine sediment that reach the channels in CEAP benchmark watersheds.
Approach:
ARS-NSL and University of Iowa researchers will work together to collect samples of potential source material, precipitation, and transported sediment in CEAP watersheds and determine the amount of naturally-occurring radionuclides using a gamma spectrometer. Work will be conducted at ARS locations in Ohio, Indiana, Missouri, Texas, Iowa, and New York. The signature of the transported sediment will reveal its source by comparison to the signatures of the source samples. Data will be available to all cooperators for analysis and reports will be generated as appropriate.
