Abstract: During February 1981 a castastrophic breakup ice jam occurred along a reach of the Delaware River near Port Jervis, NY, causing 14. 5 million in damages. In February 1982 another breakup ice jam occurred at the same location, causing much concern but minimal flooding and damages. These events prompted the Philadelphia District, U. S. Army Corps of Engineers, to conduct an investigation of the Upper Delaware River to determine if some form of ice control structure could be implemented in order to reduce ice jam-induced flooding. This paper focuses on the field investigations and analyses performed by the U. S. Army Cold Regions Research and Engineering Laboratory for the Philadelphia District during the period 1983-1985. The study included both on site and remote monitoring of ice conditions and hydraulic analysis of several ice control structure alternatives.
