Bologna sits in or near the Po Valley in northern Italy, a flat river basin with a humid subtropical climate where persistent autumn rain and occasional intense summer thunderstorms both contribute to significant flood risk.
At the edge of the Po Valley, the city’s Reno and Savena rivers are monitored closely during the region’s wetter autumn months. The Po River and its many tributaries drain this densely populated plain, and because the terrain is so flat, sustained rain can raise river levels for days even after a storm has passed, making radar an important complement to river-gauge monitoring.
