Map of runoff risk (partial cover)

The map shows the risk of water flowing overland (runoff) carrying potential pollutants into water courses. This map primarily covers the cultivated land in Scotland. The digital dataset gives information on the likelihood of a potential pollutant applied to the soil surface running off the land to a water course in 3 classes: Low, Moderate or High and is based on fundamental soil characteristics such as depth to a slowly permeable layer, soil porosity and flow pathways through the soil.

Statement

The risk of runoff depends on how easily water can drain away from the soil surface. It also depends on how much water the soil can store. These in turn depend on fundamental soil characteristics such as soil porosity and flow pathways through the soil.

Each of the soils in the Soil Map of Scotland (partial cover) dataset was first allocated to one of 29 Hydrology of Soil Type (HOST) classes and then the Standard Percentage Runoff for these classes was determined from Boorman et al. (1995). These runoff values were then allocated to one of 3 classes that reflected the likelihood of a soil becoming saturated leading to water flowing over the land. The three classes, Low, Moderate or High, equate to less than 20, 20 to 40 and more than 40 percent runoff. Where the soil map units were described as complexes (that is, more than one soil type if found in a soil map unit), the precautionary principle was applied and the soil at most risk of generating runoff was used to describe the whole map unit.
