Corrosivity Map for the UK
CorrosivityGB_v1
The dataset is a Soil Corrosivity Map for the U.K. based on the BGS DIGMapGB-PLUS Map. The creation of this dataset involves scoring the Soil Parent Material types for five different attributes that contribute towards the corrosion of underground assets. These are (i) high or low soil pH, (ii) general soil moisture, (iii) the likelihood that soil saturated and undergo periods of anaerobic conditions, (iv) the presence of sulphides and sulphates and (v) the resistivity of the soil parent material. The scoring of each of these parameters was undertaken based on the Cast Iron Pipe Association (CIPA) (now the Ductile Iron Pipe Research Association, DIPRA) rating system. By combining the scores of each parameter a GIS layer has been created that identifies those areas that may provide a corrosive environment to underground cast iron assets. The final map has been classified into three categories signifying: 'GROUND CONDITIONS BENEATH TOPSOIL ARE UNLIKELY TO CAUSE CORROSION OF IRON', 'GROUND CONDITIONS BENEATH TOPSOIL MAY CAUSE CORROSION TO IRON', 'GROUND CONDITIONS BENEATH TOPSOIL ARE LIKELY TO CAUSE CORROSION TO IRON'. The dataset is designed to aid engineers and planners in the management of and maintenance of underground ferrous assets.

asNeeded
The Corrosivity (Ferrosu) dataset comprises a series of layers (water content, pH, redox, resistivity and sulphates/sulphides) where the potential for corrosion of each of the properties is scored. The separate GIS property layers contain the scores for each property according to the Cast Iron Pipe Research Association rating (Table 1). These are then combined to give an overall corrosion rating. By having separate layers as well as a combined score layer, the user can see which of the corrosion causing factors is/are detrimental so appropriate engineering remedies can be undertaken if required. It also allows for easier and better data checking.
