Flood Warning System
MRRI, Soon Ae Chun, CSI/CUNY
The Meadowlands District (District) experiences frequent tidal and fluvial flooding. 5,100 homes and 2,100 commercial and industrial buildings have been declared within FEMA’s Special Flood Hazard Area. The average elevation of the District is only two feet above normal high tide and more than 3000 acres of landfills are impacted by any significant surge event. MRRI continuously monitors water elevation at critical tide gates in the estuary. There is a need to develop and maintain a reliable District wide water elevation warning system that informs emergency managers and citizens of current water elevations and potential flood areas in and around the lower Hackensack River.
Our primary objective is to provide emergency managers and the public with real time information on water elevation in the lower Hackensack Estuary. Our secondary goal is to provide a centralized location on the web where emergency managers and the public may post and read emergency field reports from tweets and emails.
The warning system is powered independent of the local electrical grid. Measuring stations at the tide gates and in the rivers are solar and battery powered. The electronic equipment that integrates the information from the field and generates the warning exists in a removed geographic location not to be affected by local power outages. The system’s architecture is designed as an integration of modules and automated processes which include:
