Water flow in the active layer<\/strong>
\nThe dynamics of water movement in a changing environment<\/p>\n

Assessment Committee:<\/strong>

\nAssociate professor Guy Schurgers (chair), IGN<\/p>\n

Summary:<\/strong>
\nThe hydrothermal regime of the active layer in the Arctic is changing due to altered conditions at the surface. Field experiments have been conducted at two locations in Greenland and subsequently simulated in numerical models to investigate the effects on active layer thickness, discharge and solute movement.
\nThe results show that surface changes influence the dynamic thermal properties of the soil which in turn shift the frost table position in absolute terms. As this varies the relative position of the water table, it changes the transmissivity of the active layer, and the soil layers that are hydraulically active. This results in changes of the potential discharge and alters travel velocities of solutes in the active layer.<\/p>\n
