ASTM D5906

ASTM D5906 is a technical guide that addresses how to measure horizontal positioning during measurements of surface water depths. It is designed to support more consistent field data collection by helping users relate depth measurements to a defined horizontal location. For projects that depend on accurate water-depth records, this standard can improve repeatability, data comparability, and overall confidence in the results. ASTM D5906 is especially relevant where positioning matters as much as the depth value itself.

What is ASTM D5906?

ASTM D5906, Standard Guide for Measuring Horizontal Positioning During Measurements of Surface Water Depths, provides guidance for documenting where depth measurements are taken in relation to a horizontal reference. The title indicates a focus on positioning during surface water depth work rather than on depth measurement alone. As a result, the standard is useful for users who need organized, repeatable location information to support technical reporting, survey consistency, and data interpretation. It is a practical reference for field and quality-focused workflows.

Where is ASTM D5906 used?

This guide is commonly used in surface water measurement activities where the location of each depth reading must be tracked carefully. It may be applied in field surveys, monitoring programs, mapping efforts, or similar water data collection workflows that rely on recorded horizontal positions. ASTM D5906 is relevant whenever depth measurements are tied to specific spatial references, helping users maintain a clear link between each measurement point and its mapped location.

Why is ASTM D5906 important?

ASTM D5906 helps improve consistency in how surface water depth measurements are positioned and reported. That matters for compliance, data quality, and later comparison of results across sites or over time. By supporting clearer horizontal positioning practices, the guide can reduce uncertainty in interpretation and help organizations evaluate measurements more reliably. For procurement, project specifications, and technical review, ASTM D5906 offers a structured way to reference positioning expectations.

• Horizontal positioning for depth measurements
• Surface water data collection support
• Consistent field reporting
• Improved location traceability
• Useful for technical review and QA
