Project NOAH (Nationwide Operational Assessment of Hazards) is a responsive program, launched by the Department of Science and Technology (DOST), for disaster prevention and mitigation for the Philippines' warning agencies to provide a 6 hour lead-time warning to vulnerable communities against impending floods. Advanced technology will be used to enchance current geo-hazard vulnerability maps.

The project takes a multi-disciplinary approach to develop systems, tools, and other technologies which could be operationalized by the government to help prevent and mitigate disasters.

By using science and technology, in partnership with the academe and other stakeholders, the project aims to undertake disaster science research and development, advance the use of cutting edge technologies, and recommend innovative information services in government's disaster prevention and mitigation efforts.

It's immediate task is to integrate current disaster science research and development projects and initiate new efforts within the DOST.

There are eight component projects under the NOAH Program. These include:

  • Hydromet Sensors Development- Installation of 600 automated rain gauges (ARG) and 400 water level monitoring stations (WLMS) along the country's 18 major river basins (RBs) by December 2013 to provide a better picture of the country's surface water in relation to flooding
  • Disaster Risk Exposure Assessment for Mitigation- Light Detection and Ranging (DREAM-LIDAR) 3-D Mapping Project- Creation of more accurate flood inundation and hazard maps in 3D for the country's flood-prone and major river systems and watersheds
  • Flood Information Network (Flood NET-Flood Modeling Project)- A flood center for a timely and accurate information for flood early warning systems. The project will come up with computer models for critical RBs, automate the process of data gathering, modeling and information output, and release flood forecasts.
  • Weather Hazard Information Project (WHIP)- The utilization of platforms such as television (DOSTv) and web portal ( to display real-time satellite and Doppler radar, ARG, and WLMS data to empower LGUs and communities to prepare against extreme natural hazards. The said project is to be complemented by activities like:
  1. Conduction of Information, Education, and Communication (IEC) activities
  2. Processing and packaging of relevant and up-to-date information for public use

The program team is composed of the scientist-leaders of the said projects. The warning agencies of the country, Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAG-ASA) and Philippine Institute of Volcanology and Seismology (PHIVOLCS) are represented.

In two years, the project shall provide high-resolution flood hazard maps and install 600 automated rain gauges and 400 water level measuring stations for 18 major river basins in the country. These are:

The project will also work on other river basins of the country after the work on the said major river basins is completed.

Hazard maps are tools used for localized emergency response, identification of evacuation and access routes, road closures during disaster events, siting of key rescue facilities and comprehensive land use planning. These are produced with computer simulations which reflect flood-prone areas which are discernible at a local scale or community level.

Project NOAH's initial output was focused on the Marikina Watershed. In March 2012, the following were already accessible online:

  • Streaming data from the automated rain gauges and water level sensors
  • Flood hazard maps overlain on Google Maps
  • Graphical satellite radar and Doppler data forecasts
  • Translated rain intensity and volume measurements in terms of warning and evacuation level alarms, hours or days ahead of the flood event

The said output was used to replicate the entire country. The generated information was transmitted by other media and communication channels.
