ISO 15709:2002 gives a simplified theory of the physics of soil water in the unsaturated zone and defines a set of terms, quantities, units and symbols used in the field of soil physics investigation of the unsaturated zone. ISO 15709:2002 is applicable only to standards on soil physical investigations of the unsaturated zone (including swelling soils) elaborated within ISO/TC 190. ISO 15709:2002 specifically excludes macropore flow.

Overview

ISO 15709:2002 - "Soil quality - Soil water and the unsaturated zone - Definitions, symbols and theory" provides a compact, standardized foundation for soil‑physical investigations of the unsaturated zone. The standard delivers a simplified theory of soil water physics and establishes a consistent set of terms, quantities, units and symbols used by practitioners and laboratories working on soil water, soil quality and related environmental assessments. ISO 15709:2002 is intended for use within ISO/TC 190 and specifically excludes macropore flow; it is also applicable to swelling soils.

Key Topics

Definitions and terminology for soil water and unsaturated zone investigations (e.g., water content as volume and mass fractions).

Quantities, units and symbols standardization to ensure comparable reporting across studies and standards.

Soil water potentials and equivalents:

Total, pneumatic, gravitational, matric and osmotic potentials
Pore water (tensiometer) and hydraulic potentials

Pressure and head equivalents for potentials (pressure in pascals, head in metres) and notes on measurement (e.g., tensiometers for pore water pressure).

Simplified theory covering:

Composition of the unsaturated zone
Energy status of soil water (how water is held and exchanged)
Transport of soil water (hydraulic conductivity, Darcy’s relationship, soil water retention)

Key physical parameters referenced: water retention curves, hydraulic conductivity, soil water content - essential for understanding flow and storage in unsaturated soils.

Applications

ISO 15709 is practical for:

Soil scientists, agronomists and ecologists assessing plant‑available water and soil quality.

Hydrologists and hydrogeologists modeling recharge, shallow groundwater interactions and contaminant transport through the unsaturated zone.

Environmental engineers and regulators conducting pollution risk assessments where transport of soluble contaminants is driven by soil water movement.

Civil engineers and geotechnical teams evaluating swelling soils and moisture‑related soil behavior for construction projects.

Testing laboratories and standards developers seeking harmonized definitions, symbols and theoretical background to support ISO soil physical methods.

Practical benefits include improved comparability of results, clearer communication of soil water status (matric head, pore pressure, water content) and a consistent basis for interpreting hydraulic measurements used in irrigation planning, wetland management, contamination studies and groundwater recharge assessments.
