The is an essential document for geotechnical engineers, environmental consultants, and construction quality control personnel. It provides a standardized, repeatable, and defensible method for measuring soil infiltration rate in the field.
The standard emphasizes the importance of verifying all equipment before use. This includes calibrating water-level measurement devices and ensuring the infiltrometer rings are free of any warping or damage that could compromise test results.
Tests made at the same site are not likely to give identical results, and the rate measured by this test method is primarily for comparative use. astm d338518 pdf
Industrial and municipal facilities rely on this data to design evaporation ponds and sludge drying beds.
Record the water level or volume consumed at regular, frequent time intervals (e.g., every 5, 10, 15, or 30 minutes). The is an essential document for geotechnical engineers,
Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer1
Soils need time to absorb water to accurately represent sustained infiltration. The soil must be pre-soaked. For sandy soils, pre-soaking may only take 15 to 30 minutes. For clayey soils, it can require up to several hours or even days. Record the water level or volume consumed at
Understanding how water and other liquids move through the ground is foundational to civil, agricultural, and environmental engineering. The standard is the globally recognized protocol used to measure the rate of infiltration of liquid—typically water—into soils in the field.
A common point of confusion in geotechnical reporting is mixing up infiltration rate and hydraulic conductivity (permeability).
