Rainfall adds runoff faster than low-lying ground can absorb it, especially on paved city surfaces.
River level reflects upstream conditions — heavy rain far away can flood a city with clear local skies.
Sea level rise raises the baseline that river and storm water drain into, backing up drainage systems.
Drainage efficiency models pumps, storm drains and permeable ground — higher values remove water faster.
This is a simplified reservoir (bucket) model, not a full fluid-dynamics solver — it approximates realistic trends, not exact hydraulics.
