Research Project: Development of an All-Lands Wind Erosion Model

Location: Range Management Research

Project Number: 3050-11210-009-81-A
Project Type: Cooperative Agreement

Start Date: Jan 1, 2017
End Date: Dec 31, 2019

Objective:
The broad program objective is to produce a wind erosion decision-support model and analyses that contribute to management objectives of partner agencies, including the Natural Resources Conservation Service (NRCS) and Bureau of Land Management (BLM). The research will develop a wind erosion model from existing and new theory, provide calibration and validation to establish model uncertainty across land cover types, and conduct model applications at different scales integrating data from national monitoring networks.

Approach:
Available dust emission models will be integrated into a single model code. Modifications will be made to the drag partition scheme to represent different scales of roughness in rangelands and croplands. Sensitivity tests in comparison with field measurements will be used to select key model components that provide generalizable process representation across rangelands and croplands. The model will be calibrated and validated against field measurements from the National Wind Erosion Research Network. The calibrated model will then be applied to make regional and national wind erosion assessments using available NRCS National Resources Inventory (NRI) and BLM Assessment, Inventory and Monitoring (AIM) monitoring data. The model and outputs will be packaged online so that they are accessible to the partner agencies.
