Soil Series - Leakage assessment due to Corrosivity and Shrinkage

SOILSERIES Leacs is tabular data that can be used in conjunction with any of the NATMAP products, excepting NATMAP soilscapes.

SOILSERIES Leacs provides information on the shrink-swell and corrosivity of the soil to Fe and Zn. This data set is widely used in the UK Water Utility sector - being used by most major water companies for the prediction of the corrosion rates on their underground pipe assets. It is also used for fracture potential modelling.

SOILSERIES Leacs data and description

The table below describes the various properties within this data product. Each table contains the information outlined below.

Property Example from data Description
SERIES 4 Soil series code for each series, this is a 4 digit numeric code
SHRINK_SWELL 6 Shrink-swell class, see Clayden and Hollis (1984, 33-35), Hollis (1991, unpubl), and Jones and Hollis (1996, unpubl)
CORR_FE 4 Corrosivity code for Fe, see Jarvis and Hedges (1994). If there is a '*' in this field, this indicates that there is likely to be a trace of sulphate present. If, on further investigation there is no sulphate, the class should be 1 lower. Conversely, if there is plenty of sulphate, add one to this class.
CORR_ZN 3a1 Corrosivity code for Zn, see Jarvis and Hedges (1994)
