Ensure the site has enough room to set up the rings and bring in necessary equipment.
ASTM D3385-18, officially titled “Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometers,” serves as the industry benchmark for this measurement. By utilizing a concentric ring apparatus, the method aims to minimize lateral flow divergence, thereby providing a more accurate representation of the vertical hydraulic conductivity of the soil. This paper dissects the standard, offering guidance on its practical application and theoretical basis.
The ASTM D3385-18 pdf standard does not cover all safety issues related to its use; it is the user’s responsibility to follow proper safety protocols. Where to Obtain the ASTM D3385-18 PDF astm d338518 pdf
Determining optimal water application rates to maximize crop absorption and prevent surface runoff.
The data points are plotted on a graph (Infiltration Rate vs. Elapsed Time) to visually pinpoint the moment the soil reaches its steady-state infiltration capacity. Practical Applications of the Data Ensure the site has enough room to set
The test uses two concentric open cylinders (rings) driven into the soil. The limits lateral water spread, ensuring that water from the inner ring moves vertically downward, which provides a more accurate measure of one-dimensional infiltration.
Used to drive the rings into the ground without warping the metal. This paper dissects the standard, offering guidance on
ASTM D3385-18 allows for two primary measurement methodologies: Method A: Constant Head Test (Preferred)
Before using this method, it's vital to know where it applies and where it doesn't.
