Abstract
A system for efficiently and cost effectively monitoring the status of the interface between two dissimilar media is provided. In a preferred embodiment, the system uses principles applied from the theory of time domain reflectometry (TDR), together with novel circuitry and low cost narrow band telemetry, to provide real time monitoring on a continuous basis, as needed. The circuitry involved permits operation of the system without relying on relative values of signal amplitude while employing a novel feedback function that sets the pulse repetition frequency instantaneously to permit an optimum data collection rate as well as a separate measure of the status based on the system operating parameters. It has particular application to real time monitoring and alerting to the effect of scour events in waterways.
