A Dual-Permeability Approach for Modeling Soil Water Flow and Heat Transport during Freezing and Thawing
Larsbo, Mats; Holten, Roger; Stenrød, Marianne; Eklo, Ole Martin; Jarvis, Nicholas (Peer reviewed; Journal article, 2019)Preferential flow may become significant in partially frozen soils because infiltration can occur through large, initially air-filled pores surrounded by a soil matrix with limited infiltration capacity. The objectives of ... -
The effect of freezing and thawing on water flow and pesticide leaching in partially frozen soil: Soil column experiments and model development
Holten, Roger (;2019:20, Doctoral thesis, 2019)Increased pesticide concentrations have often been detected in soil leachate, drain discharge and surface runoff during freeze/thaw periods in late winter and early spring, both in Norway and Sweden. Limited knowledge and ... -
Leaching of Five Pesticides of Contrasting Mobility through Frozen and Unfrozen Soil
Holten, Roger; Larsbo, Mats; Jarvis, Nicholas; Stenrød, Marianne; Almvik, Marit; Eklo, Ole Martin (Peer reviewed; Journal article, 2019)Field and laboratory studies show increased leaching of pesticides through macropores in frozen soil. Fast macropore flow has been shown to reduce the influence of pesticide properties on leaching, but data on these processes ... -
The effect of freezing and thawing on water flow and MCPA leaching in partially frozen soil
Holten, Roger; Bøe, Frederik; Almvik, Marit; Katuwal, Sheela; Stenrød, Marianne; Larsbo, Mats; Jarvis, Nicholas; Eklo, Ole Martin (Journal article; Peer reviewed, 2018)Limited knowledge and experimental data exist on pesticide leaching through partially frozen soil. The objective of this study was to better understand the complex processes of freezing and thawing and the effects these ...
