Our vision is for all communities to effectively use hydrologic information and warnings to protect lives, property, and the environment.

Our mission is to provide education, training, and standards for the generation, delivery, and use of timely reliable hydrologic information."

ALERT2 Technical Working Group

David Haynes, Chair

The ALERT2 Protocol Technical Working Group (TWG) designs and maintains the standards for the latest generation of wireless communication protocols for use in real-time hydrologic data collection systems. The ALERT2 protocol provides full error detection and error correction in most cases. It has been tested in several venues and has now been adopted by many other communities and organizations for meeting their real-time data collection and flood threat detection needs.
 
The current ALERT2 Protocol Specification documents are available for review and comment (see link). Please submit all comments about any of the ALERT2 documents to ALERT2@hydrologicwarning.org


NEWS 

  • ALERT2 Intelligent Network Device Application Program Interface Specification V 1.1 is now available. Click here to download.
  • NHWC ALERT2 Source Address Management System (SAMS) Appeal made on January 30, 2013. Click here for details. Then, click the following link to contribute to the ALERT2 Source Address Funding. The payee is contributing funds that will be used to develop the ALERT2 SAMS. Benefits include:
    •  Reduction in the loss of valuable data that occurs now during storm events due to radio traffic contention.
    • Capacity for 65,000 complete sites compared to 8,000 individual sensors for ALERT.
    • Provides a low-cost, minimal oversight solution.
    • A simple web-based application will allow system owners to easily request addresses for specific sites.
    • This automated process would insure that assigned addresses are not duplicated. No fees would be charged for registering or for using the SAMS. As directed by the NHWC, the TWG would be initially responsible for developing and managing the SAMS.
    • By sharing these start-up costs, participating agencies will avoid costly efforts required to resolve the problems created by inadvertent address assignment conflicts.
  • Press Release - September 15, 2010 was posted on 280 news and informational websites. Reports available through BusinessWire indicate 22,292 individuals viewed the ALERT2 news release headline and more than 1,100 viewed the full news release.
