Application Of A Hazard Rating System For Rock Slopes Along A Transportation Corridor Using Remote Sensing, Samantha M. Justice
Dissertations, Master's Theses and Master's Reports - Open
Rockfall hazards are a significant and ongoing threat to infrastructure located within steep terrain. Assessing the relative hazard along a transportation corridor is important in determining the likely location and mode of rock slope failure. Understanding where to focus attention and funds is vital for the infrastructure agencies because of the high cost of implementing preventative measures for long lengths of infrastructure. Hazard analysis has historically relied upon experienced field engineers assessing each site, which is not time or cost effective. This study focuses on using remote sensing techniques to analyze rock slopes along transportation corridors. A case study from …
Lineament Mapping For Groundwater Exploration Using Remotely Sensed Imagery In A Karst Terrain : Rio Tanama And Rio De Arecibo Basins In The Northern Karst Of Puerto Rico, Carla A. Alonso-Contes
Lineament Mapping For Groundwater Exploration Using Remotely Sensed Imagery In A Karst Terrain : Rio Tanama And Rio De Arecibo Basins In The Northern Karst Of Puerto Rico, Carla A. Alonso-Contes
Dissertations, Master's Theses and Master's Reports - Open
Remote sensing and advanced digital image processing techniques were developed and tested for delineating karst features important for the subterranean hydrology in the Tanamá River and Rio Grande de Arecibo catchments located in the North Coast Tertiary Basin of Puerto Rico, where groundwater contributes to base flow for surface water bodies which in itself is the main supply of drinking water. This aquifer region is a karst platform of carbonate rocks and clastic beds, thought to comprise a confined aquifer beneath and an unconfined aquifer. Products derived from ASTER, Landsat (ETM+ and TM), a NED DEM (30 m), and a …
