This is how happy and chocolate-colored the river Llobregat flowed down today, as it passed through Sant Boi, after the tremendous storms of the previous day. Water is life, even if it is brown, as can be seen in the Photos of the Readers of La Vanguardia.
With the last rains, the river comes down, stirred up with earth sediments. Sediment is a solid material accumulated on the earth’s surface derived from the actions of phenomena and processes that act in the atmosphere, in this case, rain.
The upper basin of the Llobregat river supplies water to the Barcelona metropolitan area and helps produce hydroelectric power.
The Llobregat rises in the municipality of Castellar de n’Hug, in the Berguedà, at 1259 meters of altitude in the Sierra del Cadí, and flows into the Mediterranean Sea, forming a swampy delta.
The day after the rains, images of the very swollen Llobregat river can be seen in its first sections in Berguedà, with charged and renewed waterfalls, while in the lower part, close to the delta, it falls loaded with sediments. Hence that color.
