After the Mondego River level dropped in Coimbra, sand accumulation was visible on the riverbed.

The phenomenon is natural and is related to the formation of sandbanks, which develop when the river current decreases, and the sediment transported by the water is deposited.

The formation of sandbanks is a natural process that occurs when the river current decreases and consequently the water level. In this process, all the sediment carried by the river water is deposited.

In February, Coimbra experienced worrying moments amid the rains that plagued the region. The rain led to flooding in the district, the rupture of a dike, and the collapse of the A1, one of the main highways in the country.
