meta-stable slope


meta-stable slope
   (not recommended: obsolete)
   A slope that is relatively stable at the present time, but may become active if the environmental balance is disturbed, for instance, by road construction or destruction of vegetation. A metastable slope is often related to base levels of former geomorphic episodes. The regolith is generally moderately deep, may contain stone lines or relict evidence of slope alluvium. Slope gradients usually range from 15 to 45 %.
   Compare: active slope.
