Claim Text:
1. A method of detecting a sediment condition in a conduit, the method comprising: a sediment-detection processor recording a baseline flow-depth signature during a first time period, wherein recording the baseline flow-depth signature comprises receiving and recording a first plurality of flow-depth measurements taken at different respective times during the first time period; the sediment-detection processor recording a second flow-depth signature during a second time period subsequent to the first, wherein recording the second flow-depth signature comprises receiving and recording a second plurality of flow-depth measurements taken at different respective times during the second time period; the sediment-detection processor making a sediment-condition determination if at least one of a minimum flow depth signature over a measurement period forms a monotonic, rising pattern and a calculated delta between the second flow-depth signature and the baseline flow-depth signature exceeds a delta threshold; and responsively outputting a sediment-condition alert via a user interface.
