Title
WR: Annual average soil water regime
Abstract

WR:Annual average soil water regime
Dominant annual average soil water regime class of the soil profile of the STU.
The annual average soil water regime is an estimate of the soil moisture conditions throughout the year. It is based on time series of matrix suction profiles, or groundwater table depths, or soil morphological attributes, or a combination of these characteristics. The annual soil water regime is expressed in terms of the duration of the state of soil wetness during the year. A soil is wet when it is saturated and has a matrix suction less than 10 cm, or a matrix potential over 1 kPa. Time is counted in cumulative days and not as successive days of wet conditions.
“Wet” means waterlogged and is defined as: a matrix suction of less than 10 cm, or a matrix potential over 1 kPa. The WR attribute is used to describe the dominant annual average soil water regime class of the soil profile of the STU. The list of authorised codes and their corresponding meaning is given in the following table for attribute WR:
