vriesdiepte
Vriesdiepte is the depth in the soil to which freezing penetrates during a winter. It is defined as the deepest layer at which soil temperatures reach or fall below 0 °C for a sufficiently long period, causing the soil below that depth to remain unfrozen. The depth is typically expressed in centimeters or meters and varies considerably with local climate and soil properties.
Measurement and determination are usually based on soil temperature data obtained with sensors placed at multiple
Several factors influence vriesdiepte. The air temperature regime (minimum temperatures and duration of subzero periods) is
Implications and usage: vriesdiepte matters for construction and engineering design (foundations, pipelines, road layers) and for
Climate trends may alter vriesdiepte over time; warming winters tend to reduce maximum frost depths, though
