Description

Public Abstract A program aimed at significantly advancing the ability to develop smarter, more efficient and more reliable commercial remote sensing and spatial information (CRS&SI) technology products applicable to bridge scour monitoring is discussed herein. A multi-level adaptive remote sensing system (MARSS) is proposed; the framework will integrate remote sensing and wireless technology for scour monitoring, adaptive information processing, prognosis and decision support systems (DSS) to provide valuable scour data, which is currently unavailable. Features from satellite images, sensors and Radio Frequency IDentification (RFID) will be combined to obtain 3D information about scour, necessary for detection and prognosis of structurally deficient bridges. The adaptive detection approaches will provide continuous and near real-time monitoring capability, while the improved DSS will significantly reduce the amount of data required for processing by DOT personnel. These features will not only make MARSS robust and applicable to different scour modes (clear-water and live-bed scour) and environmental conditions, but also cost effective. Integration of more efficient CRS&SI in MARSS could potentially result in a dramatic reduction in the number of bridges that need significant repair due to scour, limiting the time and duration of bridge closures.
