13.080.40 - Hydrological properties of soils

This Standard specifies laboratory methods for determination of the soil water-retention characteristic. This document applies only to measurements of the drying or desorption curve. Four methods are described to cover the complete range of soil water pressures as follows: a) method using sand, kaolin or ceramic suction tables for determination of matric pressures from 0 kPa to -50 kPa; b) method using a porous plate and burette apparatus for determination of matric pressures from 0 kPa to -20 k...view more

This document provides guidance on the principles behind, and main methods for, the evaluation of
sites, soils and soil materials in relation to their role as a source of contamination of groundwater and
their function in retaining, releasing and transforming contaminants. It is focused on contaminated
land management identifying and listing relevant monitoring strategies, methods for sampling, soil
processes and analytical methods.

ISO 17892-1:2014 specifies a method of determining the water content of soils.
It is applicable to the laboratory determination of the water (also known as moisture) content of a soil test specimen by oven-drying within the scope of geotechnical investigations. The water content is required as a guide to the classification of natural soils and as a control criterion in re-compacted soils, and is measured on samples used for most field and laboratory tests. The oven-drying method is the definiti...view more

EN-ISO 11275 specifies a laboratory method for the simultaneous determination in soils of the unsaturated hydraulic conductivity and of the soil water-retention characteristic. It is applicable only to measurement of the drying or desorption curve. Application of the method is restricted to soil samples which are, as far as possible, homogeneous. The range of the determination of the conductivity depends on the soil type.

ISO 11461 specifies a method for the gravimetric determination of soil water content as a volume fraction.The method is applicable to all types of non-swelling or non-shrinking soils where coring sleeves can be used for sampling. It is not applicable to soils where stones, tough roots or other factors prevent collection of soil cores. It is used as a reference method (e.g. the calibration of indirect methods for determination of water content).

ISO 11275:2004 specifies a laboratory method for the simultaneous determination in soils of the unsaturated hydraulic conductivity and of the soil water-retention characteristic. It is applicable only to measurement of the drying or desorption curve. Application of the method is restricted to soil samples which are, as far as possible, homogeneous. The method is not applicable to soils which shrink in the range of matric head 0 cm to -800 cm.

This International Standard specifies the determination of the hydraulic conductivity of granular soils (e.g. sand and gravel) using a constant-head method involving a rigid-wall permeameter to measure the laminar flow of water. The procedure establishes representative values of the hydraulic conductivity of granular soils that can occur in natural deposits as placed in embankments, or when used as base courses under pavements. In order to limit consolidation influences during testing, this proc...view more

This International Standard specifies a test method for laboratory measurement of the hydraulic conductivity of water-saturated porous materials using a flexible wall permeameter. This International Standard is applicable to undisturbed or compacted specimens that have a hydraulic conductivity between 1 × 10-5 m/s (1 × 10-3 cm/s) and 1 × 10-11 m/s (1 × 10-9 cm/s). Typical soil types falling in this category are clay, clay and sand tills, silt, peat, mud, etc.
