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.

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.

This book was released on 1979 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grace Mine Trailings Dam is an earth and rockfill embankment approximately 2,000 feet long with a maximum height of 145 feet. The dam was constructed to impound iron ore tailings slurry pumped from a nearby iron mine operated by the Bethlehem Mines Corporation. The reservoir area provides storage space for the trailings which settle out of the slurry to leave a clear water lake. A homogeneous, impervious earth embankment was originally constructed in 1956-1957 to Elevation 600. Two extension dikes were constructed to Elevation 620 in 1976-1977. These dikes are located several hundred feet to the south of the right abutment. The side slopes were 3 horizontal to 1 vertical (3H:1V) from the base of the dam to Elevation 540 and 2.5H:1V from Elevation 540 to the top of the dam.

This book was released on 1979 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kintz Creek Dam is a zoned earth embankment, approximately 1,180 feet in length with a maximum height of 36 feet. The top of the dam is 14 feet wide at Eelvation 1626.2. The earth embankment side slopes are 3 horizontal to 1 vertical (3H:1V) upstream and 2H:1V downstream. According to the as-built plans, the embankment has a central core with 1H:1V side slopes to Eelvation 1620 and a cutoff trench approximately 6 feet in depth with a 12 foot base width. The central core and cutoff trench are composed of Zone I material (silty material, classified as ML). The downstream shell to Elevation 1620 consists of Zone II material (sandy silt, classified as SP-SM). Zone III material (gravel, classified GM) forms the upstream shell and cap over the core material, and is also used as an 8-foot thick downstream filter between the Zone I and Zone II material to a minimum Elevation of 1608. A layer of Zone V material (spoil material and boulders in excess of 6inches) covers the downstream face to Elevation 1620. A 10-foot wide berm is provided along the upstream face from Elevation 1596.8 to 1597.8. According to the as-built plans, six relief wells are spaced at 50 feet along the downstream to. Flow from the wells enters a 4-foot wide drain trench that terminates at the Principal Spillway outlet (impact basin). The drain trench lies beneath a 15-foot wide berm with a slope of 10H:1V.

Dziubek and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Siegel Marsh Dam was originally constructed as a 9 foot high earth embankment with a single concrete spillway 136 feet long. At a later date, the embankment was raised 1.5 feet, the spillway was raised 3.5 feet, and an additional spillway with a length of 126 feet was added. The impoundment is situated in State Game Lands No. 218 and is used for wildlife propagation. The embankment currently consists of three sections separated by two spillway structures. The spillway currently consists of two trapezoidal shaped, broad-crested concrete weirs separated by an earth embankment. A minimum flow of at least 1.71 c.f.s. out of the reservoir is maintained by a set of stop logs on the left side of the right spillway. All of the stop logs can be removed to drain the reservoir. Hydraulic/hydrologic evaluations revealed that the spillway will pass the 1/2 Probable Maximum Flood (1/2 PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 1/2 PMF to Probable Maximum Flood (PMF) is required for Siegel Marsh Dam. The 1/2 PMF was chosen as the SDF because the dam is on the low side of the 'Intermediate' size category due to the low height of the embankment. The spillways are therefore considered 'adequate'. The inspection revealed certain items of remedial work which should be performed immediately by the owner.

This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angelica Lake Dam is an earth structure with a masonry retaining wall along the left side (looking downstream) of the downstream face. The embankment is approximately 140 feet in length with a maximum height of 30 feet and a 35-foot top width. A road is built in the crest of the dam at Elevation 228.0. The upstream face of the embankment is variable in slope, ranging from 2.5 horizontal to 1 vertical (2.5 H:1V) between Elevations 203.0 and 213.0 to 1.5H:1V between Elevations 213.0 and 223.0 to 10H:1V between Elevations 223.0 and 228.0. The downstream slope of the embankment is 2H:1V from the spillway to the right abutment. The masonry wall forms the downstream face from the spillway to the left abutment. A broad-crested concrete drop spillway with stone masonry training walls is located near the center of the embankment. The spillway crest is 39 feet wide and has a 25-foot long concrete approach apron. The crest and approach apron are at Elevatrion 213.0. The spillway drop is 15 foot to a downstream concrete apron at Elevation 198.0. The apron is 52 feet long and directs flow into the outlet channel at Elevation 196.0. The masonry training walls extend from the entrance to the approach apron to the discharge point of the outlet apron. A concrete foot bridge crosses above the spillway crest at Elevation 222.0. The outlet works consist of a 20-inch diameter wrought iron pipe through the base of the embankment to the left of the spillway. Control of the pipe is provided by a sluice gate approximately 20 feet upstream of the spillway crest.
