Scylla Drainage Control Robot
The cylla drainage control robot provides the capability to alleviate river or channel flooding.
When it did arrive at an incipient emergency, however, the robot came to life in a big way. Large gravitic focusing arrays would sprout like quills along its back from their refuge in various internal compartments to create a tractor beam array that could create 1G acceleration towards the unit for 1260 tons of water. Though that seems niggling given the immensity of even a small pluvial excess, the robot usually works in teams with its fellows to combine their beams, and they would rely more upon physics than brute force.
In cases of river or channel flooding, the Scylla would either enter the flood path directly to create a faster springflow, cycling water down the deepest part of the channel to prevent backup, or it would travel upstream and create hydrolevees by backing up the current along the banks. Coastal flooding required more ingenuity. To prevent massive tidal bulges and tsunamis, as well as cancel the storm surges from larger storms, the unit would "pluck" the sea surface at timed intervals to create wave patterns. These patterns would slosh, adding or subtracting their their energy to create destructive that would negate destructive natural waves.
