Flood Frequency Analyses
This section of the MARFC website is devoted to flood frequency analysis information for the MARFC forecasting area. It contains information on how many times floods have happened in a specific month, percentages of flood occurrence for each month, probability, and average height above flood stage.
The main function of this project is to give the user historical flood statistics for all of The Middle Atlantic River Forecast Center (MARFC) forecast points. MARFC has received numerous requests from our customers in regards to historical flood information. This project answers these requests for the much needed information.
Flood information is available in an Access database. Please email us if you are interested in receiving a copy.
What's New - 12/1/2013
We are adding flood event weather summaries written by students from The Pennsylvania State University meteorology course.
The low water tables have been updated as of 12/1/2013. The last bout of precipitation has seen water levels rise so we don't expect to update the tables for the next several days.
Boonton, NJ above reservoir and Boonton, NJ at Main Street has been split into "old" and "new" sites due to the gauge moving and a new flood stage.
The USGS has updated some of the 2012 water year crest and flow information in their peak streamflow section. We have updated this information and uploaded it to the home page.
We have added some rainfall amounts from late 2009 - 2013 in the "flood event" tables under "Event Summaries" under the "Summary Data" header. The first addition of the rainfall amounts are a little disorganized but will eventually be restructured.
Fredericksburg, VA has been split into "old" and "new" sites due to the gauge moving with a new flood stage.
We are working on adding additional information to our flood events. We are going to link NOAA daily weather maps 1871-2013, The Pennsylvania State University Reanalysis (NARR) weather maps 1976 - 2013, National Weather Service State College weather maps and some case studies. This will probably take a few months to complete.
