Walnut Gulch 60th Anniversary Celebration

March 6-7, 2014 - (937 S Old Bisbee Hwy Tombstone, Arizona)

(please try to register by February 28th)

The objectives of the conference are to re-introduce the regional soil and water conservation community to the long history, scientific infrastructure, and research products of our outdoor laboratory, the Walnut Gulch Experimental Watershed. We would also like to present some of our most recent research, in particular erosion prediction models, to begin a process of review and refinement leading to agency adoption.

  • 8:00am - 8:30am Registration (registration is free)
  • 8:30am - 9:00am Welcome and Introduction
  • 9:00am - 12:00pm Session 1 - Choose 1 of 3 options
    1. A. Treating channels to reduce erosion
      Field discussion of upland erosion control (check dams, as opposed to structures requiring more engineering in channels) including a review of older existing structures, designs that have stood the test of time, and maintenance (3 CEUs).
    2. C. Erosion processes in the field
      Review field-measured rangeland erosion rates on the Walnut Gulch Experimental Watershed including measurements by sediment samplers, sedimentation of stock tanks, rainfall simulation, 137Cesium, and rare earth studies, as well as performing measurements of slope, canopy and ground cover needed to parameterize the Rangeland Hydrology and Erosion Model (RHEM) model (3 CEUs).
    3. D. Erosion modeling with RHEM and AGWA
      How to parameterize the RHEM model, interpret results, and compare results for multiple management practices on the same hillslope. Time permitting, there will be an introduction to watershed scale erosion modeling using the RHEM model inside the Automated Geospatial Watershed Assessment (AGWA) tool (3 CEUs).
  • 12:00pm - 1:30pm Lunch (bring your own or we can arrange a lunch from Subway for $8)
  • 1:30pm - 4:30pm Session 2 - Choose 1 of 3 options
    1. B. Tour
      Tour of the 58 square mile Walnut Gulch Experimental Watershed to include rain gages, large flumes, weather stations, evapotranspiration and CO2 measurements, soil respiration, rainfall dropsize measurements, and rainfall simulation.
    2. C. Erosion processes in the field
      Review field-measured rangeland erosion rates on the Walnut Gulch Experimental Watershed including measurements by sediment samplers, sedimentation of stock tanks, rainfall simulation, 137Cesium, and rare earth studies, as well as performing measurements of slope, canopy and ground cover needed to parameterize the Rangeland Hydrology and Erosion Model (RHEM) model (3 CEUs).

  • 8:00pm End
