Flood magnitude and frequency of Chandlers Run at two sites, at Pennsauken Township, New Jersey

Six methods were used to estimate the magnitude and frequency of floods at Chandlers Run at the culvert on New Jersey Route 612, and at a second site about 2,100 feet upstream, at New Jersey Route 70 at Pennsauken Township, New Jersey. Flood magnitude and frequency calculated by the six methods, as well as drainage-basin characteristics, are included in this report. The 100-year-flood estimates for the culvert site on Route 612 range from 268 cubic feet per second to 2,050 cubic feet per second. The 100-year-flood estimates for the upstream site at Route 70 range from 246 cubic feet per second to 2,320 cubic feet per second. Flood magnitude and frequency estimates obtained by using the New Jersey Department of Environmental Protection Special Report 38 method and other pre- viously published estimates fall within the range of values estimated by using the U.S. Geological Survey transfer method with data collected from three nearby crest-stage gages.
