A NEW ICE JAM DATABASE

Ice jam data are often difficult to locate, and doing so requires a se arch of many different data sources. The US Army Cold Regions Research and Engineering Laboratory (CRREL)has compiled an Ice Jam Database th at provides information on nearly 9300 ice events in the United States . The information may be quantitative (e.g., event stage or discharge) , qualitative (e.g., a narrative description), or a combination of bot h. References are provided to serve as a basis for further investigati on. Although some selection bias may exist in the database because of its reliance on certain data sources, the database can be an asset in water resources planning and engineering. This paper is an overview of the CRREL Ice Jam Database and presents two applications of it.
