An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components without disrupting key elements of the flood warning system. In addition, the dual data path concept used in the fault tolerant design significantly improves overall data acquisition performance. More data and more reliable data acquisition will support improved flood assessment. The latest in available VHF and satellite communications technologies were combined with state-of-the-art computers and software in a system designed to reliably mitigate potential flood damages. When completed in late 1987, the Passaic River Basin Flood Warning System will be the most advanced local flood warning system in the world.
