1. A computer-implemented method for managing stormwater in a drainage system, the method 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.
