Abstract
Official abstract text for this publication.
A scour sensor and method of detecting scour in the bed of a body of water as well as a sensor and method for determining the subgrade modulus of a subgrade are provided. The scour sensor includes an elongated rod that can be driven into the bed of a body of water such that a portion of the rod is cantilevered from the bed into the water. The rod has a known dynamic characteristic that is variable depending on the amount of the rod that is embedded in the subgrade. In one implementation, the known characteristic is the natural frequency of the rod. The scour sensor further includes a sensor element for monitoring a dynamic characteristic of the rod. Methods of using and calibrating a scour sensor are also provided. Further, the sensor may be used to determine a subgrade modulus of the subgrade.
First claim
Opening claim text (preview).
What is claimed is: 1. A sensor for monitoring scour and subgrade modulus above or below a body of water or in air, the sensor comprising: an elongated rod; a sensor element mounted to the rod, the sensor element operably monitoring a desired dynamic characteristic of the rod, the desired dynamic characteristic varying depending on the amount of scour and the subgrade modulus around the rod; and a controller programmed to correlate frequency data from the sensor element into s…
