Quality assurance strategies seek to prevent, detect, and correct problems in the quality of services provided to individuals and populations. Quality improvement strategies attempt to improve quality through continuous study and modification of the services being provided. Although these approaches tend to have different quantitative techniques and philosophical perspectives, they are.

    tenance of monitoring wells is an important network management consideration. Well abandonment procedures should include consideration of the monitoring well construction, hydrogeology, and contamination at the site. The “Handbook” serves as a general reference for the numerous factors involved in monitoring well design. Monitoring plans should be specific in terms of the connections between dam operations and programmatic reporting, and the data being collected. Monitoring plans should explicitly address spatial and temporal sampling configurations, statistical analytical approaches, reporting measures, and time.

Safety of Existing Dams: Evaluation and Improvement. by National Research Council (Author), Division on Engineering and Physical Sciences (Author), Commission on Engineering and Technical Systems (Author), Water Science and Technology Board (Author), Committee on the Safety of Existing Dams (Author) & 2 more.

ISBN Cited by: Committee on the Safety of Existing Dams. Written by civil engineers, dam safety officials, dam owners, geologists, hydraulic engineers, and risk analysts, this handbook is the first cooperative attempt to provide practical solutions to dam problems within the financial constraints faced by dam owners.

It provides hands-on information for identifying and remedying common defects in concrete and masonry dams, embankment dams, reservoirs, and related structures.

Geotechnical Engineering of Dams, 2nd edition provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams and the review and assessment of existing dams. A proposal for instrumentation for monitoring potential deficiencies at existing dams must take into account the threat to life or property that the project presents.

The extent and nature of the instrumentation depends on the complexity of the dam, the size of the impoundment, and the potential for loss of life and property damage downstream. Vast quantities of dams constructed in the world are functioning properly and satisfying each anticipated purpose by appropriate management and monitoring.

However, in existing dams, the longevity is sometimes severe problem representing the aging or the sedimentation. In newly planned dams, mitigation of environmental impact or.

The guidelines are intended to ensure consistent levels of public protection when evaluating and modifying existing dams and appurtenant structures and when designing new dams and/or structures.

Therefore, it becomes very important to ensure that the existing dams continue to operate as.

Section 1 - Overview January 1, is too high in the dam it can cause a structural failure ("landslide" of the materials in the dam).

If the seepage comes to the ground surface on or below the dam and exits too fast, it can carry soil out of the dam or foundation, and cause an internal erosion or "piping" failure. Another way a dam can fail is by being overtopped and washed out.

dams, and, at the Department’s discretion, dams assigned a Condition Rating of Unsafe or Unsound, to perform an Engineering Assessment of their dam on a regular basis. This guidance represents the professional judgment of the Department’s Dam Safety Section’s engineers.

The guidance is applicable for the average dam in an average situation. Risk Management is needed at all phases of a dam project, but is also a key tool when considering adding the fully defined project scope, budget, and schedule to an owner’s capital improvement program.

The Project Risk Management process for dams generally consists of the following steps: • Risk Identification and Categorization. Chapter III - Evaluation of existing procedures 47 Chapter IV - Suggested administrative set up for the dam safety cell in the State, 59 its functions and prioritization for safety review.

Chapter V - Guidelines for determining hydro- logical safety of existing dams. 69 Chapter VI - Structural review the dam owner of any conditions identified by the instrumentation program that may be adverse to the safety of the dam.

Monitoring Planning Planning of instrumentation, whether for an existing dam, or during the design phase for a new dam, includes several.

technology, emergency preparedness plans, and review of existing dams. The agencies’ reviews and the assessment of the reviews by a Federal ad hoc interagency committee and by an Independent Review Panel showed that sound practices are generally being used, but concluded that improvement is needed in some management practices for dam safety.A focus on improving the operations of a dam does not mean that this analysis, or the search for solutions, is focused only at the dam site or river immediately downstream.

First, the objectives for reoperating a dam and restoring a river should be set within a broader framework of conservation planning prioritization.
