Research Project: Geoscience Research for Improved Ecosystem Service Evaluations and Assessments

Location: Water Quality and Ecology Research

2013 Annual Report


1a.Objectives (from AD-416):
Develop geoscience technology to assess the effectiveness of conservation practices that enhance ecosystem services at multiple scales.


1b.Approach (from AD-416):
a) Develop Geographic information system (GIS) databases to document land cover/land use and other key aspects of agricultural watersheds to allow simulations with watershed models.

b) Investigate remote sensing methods for characterization of riparian vegetative buffers, wetlands, and conservation practices for assessment with the AnnAGNPS watershed model in reducing pollutant loads.


3.Progress Report:

Development of technology to assess riparian buffer processes was incorporated within the Annualized Agricultural Non-Point Source Pollution model (AnnAGNPS). Datasets were developed for the Conservation Effects Assessment Project (CEAP)-Benchmark Goodwin Creek Experimental Watershed for identification of existing buffers, flow through buffers, and buffer characteristics. Simulations were performed using the Goodwin Creek Experimental Watershed to evaluate the implementation of riparian buffer technology within AnnAGNPS. Evaluations were made on the effect of natural buffers and buffer conservation practices on erosion from upland and channel sources.
