Processing LiDAR data to visualize soil erosion and analyze slope stability

Abstract	LiDAR data can be used in many engineering applications. These applications include, but are not limited to, highway engineering, land development, pipeline mapping and leak detection, power line mapping, cell tower mapping, forestry, mining, flood study, coast erosion, etc. The State of New York (NYS) has collected LiDAR data that cover significant area of the state. This data is made available for educational and research purposes. Data that covers the Mohawk River spans a number of counties and involves areas of the river where there has been significant meander migration and bank erosion. Due to the unstable nature of the soil forming the riverbanks and the considerable steepness of slopes at many locations, displacement, settlement, yielding, and even failure, of the foundations of some structures have been recorded. The goal of the present study was to use the LiDAR data provided by NYS to map the slopes along the banks of the Mohawk River and to detect areas where steep slopes could critical indicators of imminent failure. The data was also used to identify sections of the river where, due to sharp bents, erosion may be accelerating resulting in faster meander migration. Detecting these phenomena at early stage is key toward the prevention of catastrophic failure that can result in loss of life and property.
