Stetson and published by . This book was released on 1981 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. The Phase I inspection of the Tomhannock Spillway Dam did not indicate conditions which would constitute an immediate hazard to human life or property. However the dam has some deficiencies which require remedial work. The hydrologic/hydraulic analysis indicates that the dam will be overtopped by 1.1 feet by the Probable Maximum Flood (PMF). However, the spillway can pass the 1/2 PMF with 3.7 feet of freeboard. Therefore, the spillway is assessed as inadequate according to the Corps of Engineer's screening critieria. The visual inspection did not reveal conditions which would indicate evidence of structural displacement or instability. The conclusion derived from evaluating the factors involved in the spillway design and forces which could act on the spillway structure is that the stability will be retained under the PMF conditions providing the composite spillway facility remains in good condition and structurally integrated. Investigate the seepage at the toe of the earthfill embankment near the left abutment. The area should be monitored and records should be maintained to detect changing conditions which might affect the safety of the facility. (Author).

Stetson and published by . This book was released on 1980 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and visual inspection of the dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas which should be investigated, evaluated, and remedied. The following remedial measures should be undertaken within one year: (1) Eliminate leakage into the interior core of the dam and repair deteriorated concrete on the north abutment and at the pier separating the two sections of the dam; (2) A formalized inspection program should be initiated to develop data on conditions and maintenance operations at the facility; and (3) A flood warning and emergency evacuation plan should be developed and implemented to alert the public in the event conditions occur which could result in failure of the dam.

This book was released on 1981 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of this dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further engineering investigations. Structural stability analyses performed for this report indicate that the factors of safety are below recommended values for all conditions studied. Safety factors fall to critical levels when the dam is subjected to severe loading conditions (such as flood flows or ice loading). Immediately upon receipt of this notification, a system for providing around-the-clock surveillance of the dam during periods of unusually heavy precipitation should be developed. An emergency action plan for the notification of downstream residents should also be developed.

This book was released on 1981 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of this dam and engineering analyses which have been performed revealed that several serious deficiencies exist with this structure. Structural stability analyses, based on available information, indicate that this dam is marginally stable under normal loading conditions and is unstable when subjected to severe loading conditions (such as flood flows or ice loading). Seepage noted under and through the structure, creating wet, soft areas along the downstream toe along both ends of the dam, adversely affect the stability of the structure. Immediately upon receipt of this notification, a system for providing around-the-clock surveillance of the dam during periods of unusually heavy precipitation should be developed and implemented. An emergency action plan for the notification of downstream residents should also be developed. It is recommended that within 3 months of the data of notification of the owner, investigations into the deficiencies on this structure should be commenced. Studies of the structural stability and seepage problems, including subsurface and structural explorations are necessary. Information obtained should be incorporated into a detailed stability evaluation.

Stetson and published by . This book was released on 1979 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, additional studies should be undertaken to further evaluate conditions affecting the dam. Additional hydrologic investigations are required to more accurately determine the site specific characteristics of the watershed. Computations establish the spillway capacity at 160,000 cfs. This capacity is 28% of the Probable Maximum Flood and 56% of the 1/2 Probable Maximum Flood. The spillway is inadequate to pass the 1/2 PMF without overtopping the dam. The westerly section, Dam B, is unstable under all of the loading conditions prescribed by the Corps of Engineers' screening criteria. Therefore, the spillway structure is determined to be seriously inadequate according to the Corps of Engineers' screening criteria. The dam break flood wave is adjudged to have a significant impact on the residential structures 1/2 mile downstream. The spillway is, therefore, seriously inadequate and the dam is assessed as unsafe, non-emergency. Additional structural investigations involving borings should be undertaken to determine the affect of uplift pressure on the base of the dam and provide further analysis of the structural stability of the dam.

This book was released on 1981 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. It has been determined that the dam would be overtopped for all storms exceeding approximately 28 percent of the Probable Maximum Flood (PMF). The spillway is, therefore, adjudged as 'seriously inadequate' and the dam is assessed as unsafe, non-emergency. It is recommended that, within 3 months of notification of the owner, detailed hydrologic and hydraulic investigations of the structure should be undertaken to more accurately determine the site-specific characteristics of the watershed and their effects upon the overtopping potential of the dam. The results of these investigations and analyses will determine the appropriate remedial measures which will be required. In the interim, a detailed emergency action plan must be developed and implemented during periods of unusually heavy precipitation. Also, around-the-clock surveillance must be provided during these periods. Current inspection and maintenance procedures by the owner are inadequate. Monitoring of the reservoir levels should be expanded to include readings during peak flow periods.
