cm/s), engineers must reference the sealed-inner ring technique outlined in instead. 2. Infiltration vs. Hydraulic Conductivity

For tight clays and clay-silt matrices where the infiltration rate falls below

Executing an ASTM D3385-18 test requires careful site preparation and precise execution. Step 1: Site Selection and Preparation Select a representative, undisturbed area of soil. astm d338518 pdf

Given the natural variability of soil, the standard recommends conducting tests at multiple locations to obtain a representative infiltration rate for a given site. Test duration can vary from a few hours to several days, depending on the soil type.

Calculating irrigation requirements and water spreading efficiency. Test duration can vary from a few hours

ASTM D3385-18 is primarily designed for soils with a high to moderate permeability profile. It yields the most accurate, reproducible results in: Granular sand Silty sand Loam and sandy loam Peat and highly organic surface soils Critical Limitations

Comprehensive Guide to ASTM D3385-18: Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer Introduction It yields the most accurate

This test is most effective for fine-to-medium-textured soils. It is not suitable for highly gravelly, stony, or fractured rock formations where driving the rings causes severe soil disturbance or bypass flow paths.

Identify a representative test location free of surface debris, large roots, and heavy vegetation.
