Criteria Double Ring Infiltrometer Single Ring Infiltrometer Philip Dunne Permeameter Minidisk Infiltrometer Guelph Permeameter Tension Infiltrometer
Equipment Transportability Medium Easy Easy Easy Medium Difficult
Volume of Water Needed Medium Low-Medium Low Low Medium High
Time (hrs) Medium-High Medium Medium Low High Medium
Personnel 1-2 1-2 1 1 2 2
Cost Medium Medium Medium Low High High
Other advantages ASTM D3385 standard for measurement Simpler to use than double ring infiltrometer Easy to install in ground. Multiple measurements can be made quickly Simplest of devices May be used to measure infiltration at depth (up to 2.5 ft) Measure unsaturated hydraulic properties of soil
Measure unsaturated hydraulic properties of soil Requires large volume of water in permeable soils Requires large diameter to be accurate (minimize edge effects) Need to measure initial and final soil moisture content Small diameter -many measurements need to be made to ensure accuracy Small diameter -many measurements need to be made to ensure accuracy Typically need a sand base to ensure contact between soil and infiltrometer
