Abstract

A conceptual model is proposed for the activity of sand dune systems on the northern Great Plains that incorporates vegetation growth theory and geomorphic system theory. Dunefield activity is modeled as a cyclic phenomenon, alternating between active and stable states, with the latter as the system state attractor. The model is divide into 2 constituents parts : the activation model is qualitative and describes the transition from stable to active dunes as the result of a climatic pertubation such as drought that decreases vegetation cover; the stabilization model is quantitative and describes the transition from active to stable dunes using a logistic model of vegetation growth
