Walsh and published by . This book was released on 1981 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beatties Millpond Dam is an earthfill embankment approximately 13.9 feet high and 365 feet long with a 32 foot wide broad-crested concrete weir spillway located at the left abutment. The dam, located about 2.3 miles northeast of Old Cold Harbor, Virginia, is used for recreation. Beatties Millpond Dam is a small size - significant hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in good overall condition at the time of inspection. Maintenance of the dam is considered to be inadequate. A stability check of the dam is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 100-year flood was selected as the spillway design flood (SDF). The spillway is capable of passing up to 40 percent of the SDF or 8 percent of the PMF without overtopping the dam. A dam failure from overtopping would not significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure. However, overtopping flows from the SDF are considered detrimental to the earth embankment. Therefore, the spillway is adjudged as inadequate but not seriously inadequate.

Book Synopsis National Dam Safety Program. Scotts Millpond Dam (Inventory Number VA 05706) Rappahannock River Basin. Essex County, Commonwealth of Virginia. Phase I Inspection Report by : James A. Walsh
Download or read book National Dam Safety Program. Scotts Millpond Dam (Inventory Number VA 05706) Rappahannock River Basin. Essex County, Commonwealth of Virginia. Phase I Inspection Report written by James A. Walsh and published by . This book was released on 1981 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scotts Millpond Dam consists of two earthfill embankments located on the left and right sides of a natural knoll. Scotts Millpond Dam is a 'small' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. Visual inspection of the dam revealed several major deficiencies requiring further attention. The depth, duration, and rate of overtopping flows are considered detrimental to the right embankment and there is a high probability the embankment would fail if the SDF would occur. The spillway is adjudged as inadequate. The spillway is not adjudged as seriously inadequate since dam failure from overtopping would not significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure.

Phase I Inspection Report written by James a Walsh and published by . This book was released on 1981 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gaines Mill Dam is an earthfill embankment 14.2 feet high and approximately 305 feet long. The dam, located in Hanover County, Virginia, is used to impound water for recreational purposes. Gaines Mill Dam is a small size - high hazard dam as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in good condition at the time of the inspection. Signs of instability were not observed and a stability check of the dam is not required. The spillway is a concrete broad-crested weir, 25.8 feet long, with the elevation of the crest 2.2 feet below the minimum top of dam and located adjacent to the right abutment. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 1/2 Probable Maximum Flood (1/2 PMF) was selected as the spillway design flood (SDF). The spillway is capable of passing up to 14 percent of the SDF or 7 percent of the PMF without overtopping the dam. Overtopping flows are considered to be detrimental to the embankment. Therefore, the spillway is adjudged as seriously inadequate since dam failure from overtopping would significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure.

Download or read book National Dam Safety Program. Lake Burnt Mills Dam (Inventory Number VA-12303), Lower James River Basin, City of Suffolk, Virginia. Phase I Inspection Report written by Paul Seiler and published by . This book was released on 1979 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to Public Law 92-367, Phase I Inspection Reports are prepared under guidance contained in the recommended guidelines for safety inspection of dams, published by the Office of Chief of Engineers, Washington, D.C. 20314. The purpose of a Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general conditions of the dam is based upon available data and visual inspections. Detailed investigation and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. Based upon the field conditions at the time of the field inspection and all available engineering data, the Phase I report addresses the hydraulic, hydrologic, geologic, geotechnic, and structural aspects of the dam. The engineering techniques employed give a reasonably accurate assessment of the conditions of the dam. It should be realized that certain engineering aspects cannot be fully analyzed during a Phase I inspection. Assessment and remedial measures in the report include the requirements of additional indepth study when necessary.

Taran and published by . This book was released on 1981 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Williams Dam is an earthfill dam about 250 feet long and 28.6 feet high. Based on criteria established by the Department of the Army, Office of the Chief of Engineers (OCE), the Spillway Design Flood (SDF) is the 1/2 PMF. The emergency spillway will pass 11 percent of the PMF or 22 percent of the SDF without overtopping the crest of the dam. The SDF will overtop the dam by a maximum of 2.15 feet, reach an average critical velocity of 5.6 feet per second and flow over the dam for 3.75 hours. Flows overtopping the dam during the SDF are not considered detrimental to the embankment. The spillway is adjudged inadequate but not seriously inadequate. The visual inspection revealed no apparent problems or remedial measures in need of immediate attention. A stability check of the dam is not required. It is recommended that a formal maintenance program and warning system be established.

Phase I Inspection Report written by Michael Baker (III.) and published by . This book was released on 1981 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horners Dam is an earthfill embankment 16.7 feet high and approximately 600 feet long. The dam, is located approximately 8.8 miles southeast of Oak Grove, Virginia is used for recreation. Horners Dam is a small size - significant hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were found to be in fair overall condition at the time of inspection. Past maintenance of the dam has been inadequate. The principal spillway, located at the left abutment, is a rectangular-shaped, broad-crested reinforced concrete weir 19.4 feet wide. A 10 foot wide vegetated earth emergency spillway is cut into the right abutment. There are no facilities for dewatering the reservoir. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 100-year flood was selected as the spillway design flood (SDF). The spillway is capable of passing up to 6 percent of the Probable Maximum Flood (PMF) or 32 percent of the SDF without overtopping. Based on the present unoccupied status of the house located within the downstream channel about 200 feet downstream of the spillway, a dam failure from overtopping would not significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure. However, overtopping flows are considered detrimental to the embankment. Therefore, the spillway has been adjudged as inadequate, but not seriously inadequate.
