With HydroCrowd, Citizen Scientists can make a real impact by monitoring rainfall and other hydro-climatic data in Ecuador, Honduras, and Tanzania. No need to be a weather expert—just grab the app and get ready to dive into the world of water!

From Rainfall to Rivers: Citizen Science for Sustainable Water Management

Using the app, you can record and update rainfall measurements from designated weather stations or even your own backyard. Watch rivers rise and fall, and capture photo notes to document the weather in your area.

HydroCrowd is a project that brings together enthusiastic volunteers like you to pioneer new ways of monitoring and protecting our precious water resources. We're turning the tide on climate change impacts using Citizen Science data to improve forecasts and make evidence-based decisions.
Be part of a global movement, helping to bridge the data gap in places with limited information. Your efforts will guide future monitoring initiatives and inspire others worldwide to replicate this empowering technique, creating a better future for our planet and ensuring sustainable water management for generations to come.
