Flooding in New Jersey
The USGS reports document New Jersey floods from 1896 to the present. Early spring and winter flooding in New Jersey tends to occur as a result of widespread, steady rain of moderate intensity that falls on frozen ground. Snow and ice melt may increase the chance of winter flooding. Summer flooding resulting from thunderstorms typically occurs in small streams and is of local extent. Late summer and fall flooding associated with frontal storms, tropical storms and hurricanes can be widespread, resulting from heavy intense rains across the entire state. New Jersey's major floods are those that are the most severe in terms of magnitude, areal extent, loss of life, and property damage.
USGS Flood Inundation Mapper
The FIM Mapper allows users to explore the full set of inundation maps that shows where flooding would occur given a selected stream condition.
NJ Coastal Plain Flood Inundation Map
The flood-inundation maps show areas of potential coastal flooding from wind driven storm surge for two different simulated coastal storms.
Flood Decision Support Toolbox
Flood-inundation maps for 10 New Jersey counties show areas of potential coastal flooding from wind driven storm surge, which can be used to display a range of tidal elevations to better understand areas of potential flooding.
Flooding can be a serious problem in many parts of New Jersey. Information on floods and analyses of flood data are needed to aid in the design of bridges, culverts, dams, highways, and buildings, and for the prudent management of flood-prone areas. Documentation of floods and a more thorough understanding of flood hydrology and hydraulics will result in more effective management of flood plains and design of structures.
The New Jersey Water Science Center (NJWSC) provides information on the magnitude and frequency of floods to agencies and individuals involved in flood-protection, planning, and design. The NJWSC also develops regional flood-frequency relations for streams in New Jersey to allow flood-frequency determinations at locations without stream gages and conducts local site studies using hydrologic and hydraulic analyses.

Floods: Recurrence intervals and 100-year floods
How do we know or measure if a flood that could happen tomorrow is worse than one that happened 2, 10 or 50 years ago? If heavy rain is being forecasted does that mean that rivers are going to rise and spill over their banks and flood your neighborhood? These are some of the questions that we think about when flooding or heavy rain is forecast by public media or the National Weather Service (NWS).
