An infiltrometer is a device used to measure the infiltration rate of water through soils. It consists of two open-ended metal cylinders that are driven concentrically into the ground and then partially filled with water. As water drains into the soils, water is added to the cylinders to keep the liquid level constant. By measuring the amounts of water added to each cylinder, the operator is able to calculate the infiltration rate of the soil. From the infiltration rate, hydraulic conductivity can be calculated.

• Researched the instrument's compliance with ASTM D3385-94 "Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer" for measuring the infiltration rate of soils.
• Developed a standard operating procedure (SOP) for use by students in Sophomore Clinic, Geotechnical Engineering courses, and Junior/Senior clinics.
• Set up the infiltrometer in the field in order to check the SOP.

The SOP includes clear instructions for setting up the infiltrometer, keeping the water level, taking readings, as well as sample data sheets for recording data and an Excel spreadsheet for performing calculations.
