Green infrastructure and open environments: London’s foundations: protecting the geodiversity of the capital, Supplementary Planning Guidance, published by the Mayor of London in March 2012, defines solifluction as: ‘…a slow downslope flow of water-saturated fragmental material or soil. It is promoted by the existence of permafrost which traps snow and ice melt within the surface layer making it more fluid.’
