Phase I Inspection Report written by James A. Walsh and published by . This book was released on 1979 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 condition 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. In reviewing this report, it should be realized that the reported condition of the dam is based on observations of field conditions at the time of inspection along with data available to the inspection team. In cases where the reservoir was lowered or drained prior to inspection, such action, while improving the stability and safety of the dam, removes the normal load on the structure and may obscure certain conditions which might otherwise be detectable if inspected under the normal operating environment of the structure. It is important to note that the condition of a dam depends on numerous and constantly changing internal and external conditions, and is evolutionary in nature.

Phase I Inspection Report written by James A. Walsh and published by . This book was released on 1979 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Buffalo River No. 3 is a zoned, earthfill dam approximately 500 feet long and 60 feet high. The dam, located on Stonehouse Creek approximately 7 miles northwest of Amherst, Virgina, is used for flood control. Visual inspection and office analysis indicate no deficiencies requiring emergency attention. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the Probable Maximum Flood (PMF) was selected as the spillway design flood (SDF). The Soil Conservation Service (SCS) freeboard hydrograph (which establishes top of dam) is essentially equal to the PMF hydrograph. The spillways will essentially pass the PMF without overtopping the dam, and are therefore considered adequate. The dam and appurtenant structures were found to be in generally good condition. No conditions indicating embankment instability were detected during the field inspection and office analyses.

Walsh and published by . This book was released on 1979 with total page 51 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 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Elon Water Works Dam is a zoned earth fill dam approximately 52.1 feet high and 490 feet long. The dam is classified as an intermediate size dam with a significant hazard classification. The emergency spillway is an earthen channel with a trapezoidal cross section at the left abutment. The principal spillway is a concrete drop-inlet with a fixed crest elevation of 663 feet. The reservoir is used for water supply. 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 32 percent of the PMF or 64 percent of the SDF without overtopping the dam. The SDF will overtop the dam by a maximum of 1.2 feet, reach an average critical velocity of 5.1 feet per second and flow over the dam for 2.4 hours. The emergency spillway is adjudged inadequate, but not seriously inadequate.

Walsh and published by . This book was released on 1979 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Johns Creek No. 2 Dam is a zoned, earthfill dam approximately 650 feet long and 51 feet high. The dam, located approximately 18 miles southwest of New Castle, Virginia is used for flood control. Johns Creek No. 2 Dam is an 'intermediate' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. 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 SDF was routed through the reservoir and found to overtop the dam by a maximum depth of 2.1 feet with an average critical velocity of 3.8 f.p.s. Total duration of dam overtopping would be approximately 3.2 hours. The dam and appurtenant structures were found to be in generally good overall condition. No conditions indicating embankment instability were detected during the field inspection and office analyses. Seepage at the toe of the dam is not considered serious; however, it is recommended that the rate be checked for increase at higher reservoir levels. The safety factors determined during design are greater than those required for minimum accepted stability.

Taran and published by . This book was released on 1981 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dam is an earthfill structure about 738 feet long and 40.5 feet high. The dam is classified as 'intermediate' on the basis of size, and given a hazard classification of 'significant' on the basis of downstream area development. The principal spillway consists of an octagonally shaped concrete riser with eight rectangular openings serving as drop inlets. The emergency spillway is an open concrete channel cut at the right abutment. The spillway will pass 41 percent of the PMF or 82 percent of the SDF without overtopping the crest of the dam. The spillway is adjudged inadequate but not seriously inadequate. The visual inspection revealed no apparent problems and there are no immediate needs for remedial measures.

Phase I Inspection Report written by James A. Walsh and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little Creek Reservoir Dam is an earthfill embankment 67.0 feet high and approximately 1,900 feet long. The dam has a drop-inlet spillway consisting of a 13 foot by 18 foot concrete riser with a 6 foot diameter concrete outlet pipe. The dam, located near Toano, Virginia, is used for water supply by the City of Newport News, Virginia. The dam is owned by the City of Newport News, Virginia. Little Creek Reservoir Dam is an 'intermediate' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspections of Dams. The dam and appurtenant structures were found to be generally in good overall condition. Visual inspection and office analyses indicate deficiencies requiring remedial treatment. A stability check is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the Probable Maximum Flood (PMF) was selected as the spillway design flood (SDF) for Little Creek Reservoir Dam. The spillway is capable of passing up to 88 percent of the PMF without overtopping the dam. Despite the inability of the spillway to pass the SDF, the depth, duration, and rate of overtopping flows are not considered detrimental to the embankment.
