Start Date: May 01, 2011
End Date: Jul 01, 2013
Tasks to be Completed: a) Develop and test the necessary code to calculate ephemeral gully erosion. b) Develop, insert and test the necessary code to calculate soil organic carbon/matter from the existing parameters that are currently being tracked in RUSLE2. c) Develop, insert and test the necessary code to calculate residue degradation rates separately for above ground and below ground residue/roots. Tasks to be performed on a continual basis during the term of this agreement: a. Develop the RUSLE2D version of RUSLE2 that has the functionality of the latest version of RUSLE2 and the added spatial erosion output potentially useful for inclusion in the CDSI effort. b. Train the key NRCS personnel on database development. c. Provide technical support to NRCS throughout the term on this Agreement, including addressing any bugs or other problems with the RUSLE2 model due to the insertion of new code associated with this contract. d. Keep the NRCS Responsible Person informed of any changes to RUSLE2 model. e. Provide support to the DLL version in NRCS’s efforts to make it capable of utilizing the NRCS Land Operations Management Database (LMOD) and National Soils Database data. f. Evaluate the Soil Organic Matter subroutine across several areas nationwide to determine if it provides satisfactory results. g. Evaluate the accuracy of the newly inserted concentrated flow erosion subroutine into the RUSLE2 program. h. Evaluate the effect of degrading above ground and buried residue pools at different rates.
