SOILM – Percentage of soils with medium infiltration capacity [%]

1. Catchment Descriptors Soil (1) 1 3 • The classification of the soil water regime was based on a study by the Regional Authority for Geology, Commodities, and Mining of Baden-Württemberg (LGRB). They produced a 1 : 350 000 scale map of 29 soil water regime classes based on soil type, humus content, packing, slope, and geology. • These classes were aggregated to four groups of soil types based predominantly on their infiltration capacity, which is defined as the “maximum rate at which water can be absorbed by a given soil per unit area under given conditions” (IHP/OHP 1998). • SOILH – Percentage of soils with high infiltration capacity [%] • These soils exhibit a high infiltration capacity even under conditions of high antecedent soil water content, such as sand and gravel soils. SOILM – Percentage of soils with medium infiltration capacity [%] Examples of soils which feature a medium infiltration capacity are loamy soils and loess of medium depth. SOILL – Percentage of soils with low infiltration capacity [%] The low infiltration capacity of these soils is due to their fine texture and/or the impermeability of one or more layers, as found in shallow sandy and loamy soils. SOILVL – Percentage of soils with very low infiltration capacity [%] The infiltration capacity in these soils is very low because they are shallow, composed of hardly permeable material (such as clay) or have a high ground water level.
