This study aims to provide insights on considering climate boundary conditions, including rainfall, snowmelt, climate variables and vegetation cover, to the stability of an unsaturated slope prone to failure in Norway.. Water entering the soil at the ground surface . It replenishes the soil moisture deficiency and the excess moves downward by force of gravity called deep seepage or percolation and builds up the ground water table .
