Leaky Rivers

Global Nominee

Leaky Rivers received a Global Nomination.


Develop a web tool, mobile device app or add-on for existing apps or websites that leverages NASA imagery and climate data to illustrate the impacts of our changing Earth in areas of interest to you. Some ideas to explore include:

  • Use NASA Earth observations data, social media, smart phones, and Short Message Service (SMS) text phones to collect Earth observations and connect public in local, regional, and national networks to communicate about our changing planet.
  • Examine current natural events curated by NASA’s EONET (Earth Observatory Natural Event Tracker) by browsing global historical and near real-time imagery from space.
  • Upload images or other data points demonstrating visible observations and how they compare to satellite data. For example, generating early-warning alerts or validating precipitation rates reported from NASA’s Global Precipitation Measurement Mission.
  • Integrate NASA imagery with a mobile assistant to allow for dynamic image generation based on a basic request structure.

Recently there has been major flooding in Houston, TX, USA. People >> friends << lost their homes because they were not equipped with a sufficent warning system. The daily news has not been able to provide necessary real time and high resolution data on the rising water level around their homes. They have lost everything!

FLOODS happen anywhere on Earth.

Our unique approach is to combine Internet of Things (IoT) sensor data on water levels and satellite imagery from NASA's MODIS program with real time and geolocated messages on Twitter. Tweets are filtered on #flood. A tone analysis is performed and it rates people's sentiment. And people in risk areas are warned.

This flowchart gives an overview of the current Leaky Rivers implementation. For rapid prototyping purposes we are using IBM Bluemix as cloud based developer platform. Different Services are deployed there:

  • Twitter Tone Analyzer
  • Weather Forecast Service
  • IoT Integration Platform (for RasPi and other devices)
  • Database System

As external resources and tools we integrated:

  • Open Layers as Map service
  • NASA MODIS EO data on floods

The product is a responsive web page that immediately gives an accurate overview of the flood threat level based on your geolocation. Please visit our web application here.

We - the LeakyRivers team created a solution to the #EarthLive challenge. Because of its modular concept it can be adapted to warn people about other catastrophes as well.
