Federal, state and local agencies need flood-peak data for zoning, building permitting, and flood protection. Flood data needed are high-water elevations, flood discharges, and flood-frequency information. Stankowski in 1974 developed equations relating peak discharge to basin characteristics. Forty-six percent more station years of flood data are now available for analysis. Much of the additional data available are for small drainage areas where Stankowski equations were weak.
Project Start Date: 01-OCT-1981
Project Number: LJ00AAP
Statement of Problem
Real-time flood stage, tide level and rainfall data is needed to allow emergency managers to execute evacuations
Strategy and Approach
(1) Data through 2004 for unregulated gaging stations and crest-stage gages in New Jersey will be analyzed by the guidelines in Water Resources Council Bulletin 17B. (2) A network of crest-stage gages will continue in operation to provide annual peak discharges and stages. The network will be reviewed annually to eliminate stations with sufficient record and establish new stations that fulfill current needs or fill voids in the knowledge of the variability of floods. (3) A network of radio/and or GOES satellite-reporting stage, precipitation and other meteorological sensors will continue in operation and be expanded as funds become available. Data collected will be shared with the National Weather Services as well as local emergency management agencies via a dedicated radio-backbone system.
