This book was released on 1980 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hilltown Dam is owned by the Neshaminy Water Resources Authority and maintained by Bucks County. The dam and reservoir are used as a flood control structure for the downstream town of Chalfont, Pennsylvania. The impoundment was designed by the United States Department of Agriculture, Soil Conservation Service, in 1977, and the structure was officially completed in 1980. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as an 'Intermediate' size structure with a 'High' hazard classification, consistent with its potential in the event of failure for extensive property damage and loss of life downstream of the dam and in Chalfont, Pennsylvania.

This book was released on 1980 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: SCS PA 477 is a 52-foot-high, 1,550-foot-long dam. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. About 1,270 feet of the embankment is roughly parallel to U.S. Route 22/Interstate 78. The remaining 280 feet of the embankment forms an angle of about 60 degrees with the highway. The shorter leg contains the maximum section and the principal spillway. The principal spillway consists of a concrete drop inlet riser, a 222 foot long, 30 inch reinforced concrete pipe with eight anti-seep collars, and an impact basin. The emergency spillway was excavated through rock at the right abutment. The grass-lined trapezoidal channel is approximately 150 feet wide and 30 feet wide. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.

Beck and published by . This book was released on 1980 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection indicates that the dam and spillway structures of Broomalls Dam are in poor conditon. In 1970, the original spillway capacity was supplemented by the installation of three 27 inch by 43 inch corrugated metal pipe arches, with an entrance invert about five inches above the spillway and discharging at the downstream toe. The November inspection disclosed that surface erosion above the pipes had occurred, probably as a result of surface runoff over the downstream parapet wall. Some erosion below the culvert outlets was evident. Subsequent inspection in February 1980, disclosed considerable erosion and apparent piping at the downstream end of the culverts. One culvert was filled with ice at its outlet and had a column of ice reaching from the outlet to the ground surface. Ice was also visible at the junction of the culverts and embankment. There appears to be a small, constant, undetermined source of water for ice formation. At the requests of local Department of Environmental Resources officials, the Reservoir has been lowered about 2.5 feet through the upper drain. As a result of the rapid deterioration in the condition of the dam since November, the dam is considered to be in an 'Unsafe, nonemergency' condition.
