Astm D338518 Pdf Better -

The movement of water through the soil surface, known as infiltration, is a fundamental hydrologic process. It governs the partitioning of rainfall into surface runoff and subsurface storage, influencing everything from flood forecasting and irrigation efficiency to the design of stormwater management systems and landfill liners. Accurate quantification of the infiltration rate is essential for civil engineers, hydrologists, and environmental scientists.

To properly execute the test according to the ASTM D3385-18 manual, specific equipment standards must be met:

Concise takeaway

: Most effective for relatively uniform, fine-grained soils with moderate to low resistance to penetration.

: This test cannot be performed if the soil surface is below the groundwater table. For extremely low infiltration rates, experts often refer to ASTM D5093 (sealed inner ring method) instead. The Double-Ring Method: How It Works astm d338518 pdf

Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer

Typically 12 inches (approx. 30 cm) in diameter.

The double-ring infiltrometer solves this problem by using two concentric rings: The movement of water through the soil surface,

Whether you are designing a septic system, evaluating a stormwater management facility, or conducting environmental site assessments, ASTM D3385-18 provides the standardized methodology you need for reliable, comparable infiltration rate measurements.

: Designing Sustainable Drainage Systems (SuDS), retention ponds, and bioswales.

Precision, bias, and revisions

Acts as a buffer zone. It promotes purely vertical water flow beneath the inner ring by saturating the surrounding soil profile. To properly execute the test according to the

: Used for evaluating liquid waste disposal sites, septic-tank fields, irrigation requirements, and potential leakage in canals or reservoirs. Scope and Soil Applicability

: Designing sustainable urban drainage systems (SuDS), retention ponds, and bioswales.
