WebJan 1, 2014 · Bed materials range from hard beds, which are characterized by lithified materials, to unconsolidated sediments such as till, sands, and gravels (soft beds). An additional complexity is that particles eroded from the bed can become entrained within the base of glaciers to form basal ice, which has mechanical properties that are quite … WebAt low effective pressures characteristic of glaciers on soft beds, τ sp is the sum of regelation-limited drag on small particles and ploughing-limited drag on larger particles.
