Four sensors, thirty-eight nodes

Run the analysis to reconstruct the network state from four deployable readings and rank the conduits most likely to be restricted.

Command centre

Where a blockage most likely is, and how confident the model is that it is there.

Network at rest. Four proposed sensor locations are online.

What four sensors recover

Peak depth at every modelled node, upstream on the left and the outfall on the right. Square-root vertical scale to 3.50 m, because peak depth is heavily skewed and a linear axis would crush both thresholds into the floor.
