Problem:

There are extensive areas of soils in Michigan that have
highly fluctuating water tables within four feet of the soil
surface. Very little is known about the dynamics of these
water tables. This information is of interest to the Forest
Service and the Natural Resource Conservation Service
(NRCS) for developing both soil and ecological site
characteristics. Currently the data collection devices
being used are prone to vandalism, and collection of data
is costly and time consuming.

Goal:                  Section 2

The goal of this project is to develop a device that is;

1. Relatively low cost to purchase and maintain,

2. Capable of recording a water column height to an
   accuracy of one-inch or better,

3. Easy to operate (program & download),

4. Will store up-to one year of data,

5. Can be easily concealed.

Project Summary:


1. Continue field testing until the beginning of Summer
   2002.
   • All units met performance requirements.

2. Publish a final report at the end of FY 02.
   • Document will remain Web-based to enable product
      updates.

Field Test Plan Outline

1. Upon receipt of test systems SDTDC will retrofit each
   system for installation into a 2-inch well casing at the test
   site and ship them to Region 9 (R9) for installation.

2. Test locations shall be selected by R9.

3. SDTDC will assist, observe, document and photograph
   installation of the test systems in R9.

Field Test Plan Outline

4. SDTDC monitored data downloading during 8 months of
   use by R9. SDTDC photographed and documented data
   downloading, and system reprogramming.

5. After one season of use, the systems were inspected for
   deterioration or mechanical failure.

6. R9 and SDTDC compared observations and
   collaborated their findings into a project report. All tested
   systems met requirements; buyers may select a product
   based on features and pricing offered.
