READING THE RESULTS
The issued engineering report compares a uniform 107 mm / 3 h storm in a 600 × 600 m local model. The intervention run shown stops at 3 h 15 min. The baseline snapshot is at 3 h 14 min.
The model boundary has no outflow or infiltration. Street capture is represented, but the individual street pumps and rising mains are sized by engineering calculation, not separately hydraulically simulated. The regional aquifer is an assumption, not a site bore log.
Three-dimensional views show proposed engineering geometry. The interactive mesh is a visual exploration, not a live simulation. No fresh model is launched by any control on this page.
Recharge trenches are an analytic proposal and are not credited in the displayed simulation benefits. Ground-use percentages are concept-design classifications.
