Multi-Scale Multi-Season Land-Based Erosion Modeling and Monitoring for Infrastructure Management

Soil erosion susceptibility is a function of intrinsic soil properties, soil states, geology, land cover, topography, and external forces (seismic events or applied load). In the New England region, erosion-prone zones have been the main source of erosion, particularly when major storms occur. With recent and continuing climate change influencing weather patterns—specifically causing an increase in high-intensity rainfall events, and rainfall events following snow events—soil erosion and landslides are of concern. With minimal operational resources and funding available for maintenance and repairs, effective screening tools used for modeling, monitoring, and forecasting erosion can aid in assessing erosion and landslide susceptibility which is important for regional operations and planning. The objective of this research project is to develop a slope stability model that will be used to create an effective multi-scale assessment toolkit that aids in monitoring, forecasting, and prioritizing areas of erosion and slope stability.
