This book was released on 1979 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brush Valley Dam is an earth embankment with a maximum height of about 21 feet and an approximate length of 920 feet. The top of the dam (Elev. 1128.0) is 16 feet wide. The upstream slope is 2.5 horizontal to 1 vertical(2.5H:1V), and is protected with riprap. The downstream slope is 2 horizontal to 1 vertical (2H:1V) and is surfaced with grass. An ungated overflow spillway is located about 200 feet from the right abutment. The crest of the spillway (Elev. 1123.0) is about 52 feet long. The control section is concrete, while the downstream slope is surfaced with riprap set in motar. A timber decked steel beam bridge supported by 3 intermediate piers, provides access across the spillway. A 16-inch diameter cast iron pipe is located at the base of spillway section. The upstream end of the pipe is joined to a submerged intake structure. This structure is fitted with screens to prevent debris from entering the pipe. Pipe discharge is controlled by a valve located at the downstream end of the pipe in the center of the spillway channel. The valve is operated manually and diverts flow either to a pumphouse or to the downstream channel. Based on a review of the available drawings, no upstream control valve is positioned on the pipe. The pumphouse is located at the toe of the embankment about 400 feet from the left abutment. Water is pumped from Brush Valley reservoir to a distributing reservoir about 8,000 feet to southeast. The distributing reservoir is about 600 feet above the level of Brush Valley reservoir. (Author).

Mihalcin and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possibly loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store approximately 92 percent of the PMF prior to embankment overtopping. Based on screening criteria contained in the recommended guidelines, the spillway is considered to be inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included a seepage condition along a portion of the downstream embankment toe approximately 160 feet to the right of the left abutment hillside and a minor vertical crack in the concrete spillway overflow wall.

This book was released on 1979 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Struble Dam is a zoned earth embankment, approximately 1,500 feet in length with a maximum height of 31 feet. The dam, a multiple purpose structure, was constructed as a portion of the Brandywine Creek Watershed Project. The reservoir has a normal pool storage capacity of 1,025 acre-feet for sediment accumulation and fish and wildlife. The normal pool surface area is 146 acres. An additional storage capacity of 596 acre-feet is utilized for flood water control. The top of dam elevation is 625.5, the crest width is 14 feet, and the side slopes are 3 horizontal to 1 vertical (3H:1V) upstream and 2.5H:1V downstream. A 12-foot wide berm is provided on the upstream face at Elevation 612.8 and the slope is lined with 18-inch thick riprap from the berm to Elevation 618.8. According to the 'As-Built' plans, the upstream and central portions of the embankment are composed of Zone I material, which is classified as a clayey silt. The central portion includes a cutoff trench with a 12-foot bottom width. The downstream shell (to Elevation 615.8) of Zone II material is classified as silty sand. The two zones are separated by a four-foot wide chimney drain which terminates in a drain trench at the downstream toe of the Zone I material.

Williams and published by . This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Township Line Dam is an earth embankment approximately 530 feet long with a height of 34 feet and crest width of 10 feet. The dam, originally constructed to impound and supply water for the Borough of West Chester, is presently being used for recreation, flood abatement and maintenance of a minimum discharge into the East Branch of Chester Creek. The concrete Ogee spillway has a crest width of 50 feet and is located at the south dam abutment. The spillway, for this 'Intermediate' size, 'High' hazard dam, is capable of discharging 48 percent of the PMF without overtopping of the earth embankment. A review of the hydrologic analysis indicates that the embankment would be overtopped by 0.15 feet for about 2 hours during a flood equal to 50 percent of the PMF. It is considered unlikely that the dam would fail during this event; therefore, the spillway is classified as 'Inadequate', but not 'Seriously Inadequate'. Based upon visual observations, review of the information obtained from the Pennsylvania Department of Environmental Resources, Division of Dam Safety, and conversations with the Owner's representative, Township Line Dam is considered to be in fair condition. However, the detection of potentially unstable conditions at this site was severely restricted due to thick vegetation covering the entire embankment. Certain conditions require further investigations, maintenance, or monitoring.

Dziubek and published by . This book was released on 1980 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parker Dam is classified as a 'Significant' hazard - 'Small' size dam. The dam and reservoir, owned by the Commonwealth of Pennsylvania, Department of Environmental Resources, are used for recreational purposes. The dam and appurtenant structures were found to be in good overall condition at the time of the inspection. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Parker Dam. Since the dam is in the middle of the 'Small' size category according to storage capacity, the 1/2 PMF was selected as the SDF. Hydrologic/hydraulic evaluations, performed in accordance with procedures established by the Baltimore District of the U.S. Army Corps of Engineers, revealed that the available spillway capacity is much greater than the maximum flow expected during the SDF. Therefore, the dam will not be overtopped during the SDF and the spillways are considered to be 'adequate'.

Dziubek and published by . This book was released on 1980 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: PA 485 is a zoned earthfill embankment with a total length of 630 feet, including the emergency spillway on the left abutment. The height and crest width of the embankment are 78 feet and 14 feet, respectively. The embankment was constructed using three zones of fill material. The principal spillway is a drop-inlet structure consisting of a two stage reinforced concrete riser connected to a 30 inch diameter reinforced concrete outlet pipe. The emergency spillway for the dam is located at the left abutment. It consists of a vegetated trapezoidal channel with a bottom width of 50 feet and 2H:1V side slopes. Hydrologic/hydraulic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. A spillway design flood (SDF) equal to the PMF is required for PA 485. The spillway is therefore considered to be 'adequate'. The visual inspection revealed several minor deficiencies which require remedial action by the owners of the dam.

Y. Chen and published by . This book was released on 1979 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The H.B. Norton Dam consists of an earthfill embankment approximately 37 feet high and 675 feet long. A 75-foot wide, concrete ogee spillway is located at the right abutment, and a 150-foot wide emergency spillway is located at the left abutment. Seepage control is provided by a steel core wall comprised of 72-inch by 96-inch by 1/4-inch steel sheets, which are riveted and welded in place. The downstream embankment rises at a slope of 2 horizontal to 1 vertical (2H:1V) to the crest at elevation 1422.4 feet. The upstream slopes rise at 2.5H:1V to elevation 1412 feet and then 2H:1V to the 12-foot wide crest. The upstream face is lined with well-placed sandstone riprap, typically 1- to 2-foot square. The ogee type spillway has a crest elevation of 1415 feet, or 7 feet lower than the top of dam. Approximately 225 feet to the left of the ogee spillway is a concrete screen chamber built into the embankment. The intake consists of two pipes, a 16-inch cast-iron pipe with an invert elevation of 1400 feet and a 36-inch cast-iron pipe with an invert at elevation 1386.0 feet.
