A Wave of Awareness: "Ola Azul" Mobilizes Hundreds to Clean Up Streams in La Paz this March 2026

Citizen participation has become the engine of environmental recovery in the state capital. This March 2026, the "Ola Azul" (Blue Wave) initiative carried out one of the most ambitious cleanup days in the stream beds of La Paz. With a volunteer force of families, youth, and activists, the operation focused on removing tons of waste that would otherwise pollute the La Paz Bay during the upcoming rainy season.

From channel hydraulics and risk management perspectives, solid waste in a dry bed drastically alters the Manning roughness coefficient. According to Manning's Equation, flow velocity decreases when obstacles (trash) increase friction, which can lead to lateral flooding in inhabited areas.

In 2026, "Ola Azul" has proven that civil organization can effectively complement government efforts. During the day, everything from single-use containers to furniture and tires was collected. The organization called on authorities to toughen fines for those caught dumping debris in these federal areas.

In conclusion, residents of neighborhoods adjacent to the streams are recommended to monitor and report any illegal garbage dumping. For the remainder of 2026, "Ola Azul" is expected to perform similar interventions in other critical points of the municipality.
