Abstract:

The proposed research investigated 3D dynamics of landscapes undergoing rapid transition from one state to another, for example due toconstruction or establishment of military training areas. The focus was on identification of the vulnerable phases in the progression ofmetastable landscapes, and investigation of the most important differences between sustainability of natural and intensively used lands. Thepossibility to find or define special configurations, rules or general laws of landscape development patterns that lead to stable landscapes was explored using a unique modeling system based on coupling of a tangible physical laboratory model, GIS-based virtual models, and numerical simulations. The simulation results were projected over the laboratory model with the aim to study physical processes and conditions that can elucidate poorly understood aspects of landscape dynamics and lead to improved knowledge about response of landscapes to disturbances, with focus on change in runoff and sediment transport. The tangible model was be used to generate land management alternatives that served as inputs to simulations of landscape response disturbances and modifications, and assessment of effectiveness of various approaches to prevention, control, and mitigation.
