Prediction of Scour Depth in Gravel Bed Rivers Using Radio Frequency IDs: Application to the Skagit River

Description: The overarching goal of the proposed research was to develop, test and verify a robust system based on the Low Frequency (134.2 kHz), passive Radio Frequency Identification (RFID) technology to be ultimately used for determining the maximum scour depths near the proposed flow deflection structures located at MP 100.7 on the Skagit River. For the purposes of this study, a RFID system was assembled and utilized for developing calibration curves that relate signal voltage or equivalently RSSI (Received Signal Strength Indicator) with distance via detailed experiments for a range of stream bed conditions (i.e., gravel- and sand-size bed material) in laboratory and quarry environments.
