= Infiltration rate (typically expressed in cm/hour or mm/hour).

A report based on the ASTM D3385 standard should include: = Infiltration rate (typically expressed in cm/hour or

The water levels in both rings must be kept equal throughout the entire test to avoid horizontal pressure gradients. Step 5: Data Recording

The standard emphasizes that while highly effective, the double-ring method is not universally applicable to all soil profiles. Ideal Soil Conditions

To provide baseline empirical data for engineering designs requiring fluid containment or seepage. 2. The Science Behind the Double-Ring Infiltrometer
