Decoupling tidal effects from water depth measurements in stormwater drainage systems

A system comprising:

• one or more hardware processors;
• and
• one or more computer-readable media having executable instructions embodied thereon, which, when executed by the one or more processors, cause the one or more hardware processors to execute actions method for managing stormwater in a drainage system, the actions comprising:
• receiving first drainage sensor data that encodes an indication of a first time-series of a depth of a fluid detected at a set on monitoring points within the drainage system, wherein the fluid associated with the first drainage sensor data includes at least tidal-backflow water from a body of water that is subject to a tidal effect;
• receiving first tidal sensor data that encodes an indication of a first time-series of the tidal effect of the body of water;
• generating a depth model based on the first drainage sensor data and the first tidal sensor data, wherein the depth model models one or more statistical-correlations between the first time-series of the depth of fluid and the first tidal effect of the body of water;
• and
• receiving second drainage sensor data that encodes an indication of a second time-series of the depth of the fluid detected at the set on monitoring points within the drainage system, wherein the fluid associated with the second drainage sensor data includes at least stormwater and the tidal-backflow water from the body of water;
• receiving second tidal sensor data that encodes an indication of a second time-series of the tidal effect of the body of water;
• and
• determining a first component of the second time-series of the depth of the fluid based on the depth model, the second drainage sensor data and the second tidal sensor data, wherein the first component of the second time-series of the depth of the fluid indicates a depth associated with the stormwater.

One or more computer storage media storing computer-usable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform actions for managing stormwater in a drainage system, the actions comprising:

• receiving first drainage sensor data that encodes an indication of a first time-series of a depth of a fluid detected at a set on monitoring points within the drainage system, wherein the fluid associated with the first drainage sensor data includes at least tidal-backflow water from a body of water that is subject to a tidal effect;
• receiving first tidal sensor data that encodes an indication of a first time-series of the tidal effect of the body of water;
• generating a depth model based on the first drainage sensor data and the first tidal sensor data, wherein the depth model models one or more statistical-correlations between the first time-series of the depth of fluid and the first tidal effect of the body of water;
• and
• receiving second drainage sensor data that encodes an indication of a second time-series of the depth of the fluid detected at the set on monitoring points within the drainage system, wherein the fluid associated with the second drainage sensor data includes at least stormwater and the tidal-backflow water from the body of water;
• receiving second tidal sensor data that encodes an indication of a second time-series of the tidal effect of the body of water;
• and
• determining a first component of the second time-series of the depth of the fluid based on the depth model, the second drainage sensor data, and the second tidal sensor data, wherein the first component of the second time-series of the depth of the fluid indicates a depth associated with the stormwater.
