INSTRUMENTATION OF EMBANKMENT DAMS AND LEVEES

Whether analyzing data to determine the competency of a sensor, planning a new system for a rehabilitation project, or selecting a sensor for retrofitting a system with automation, responsible personnel must take the initiative to observe the conditions that require attention, asssess what action is appropriate, and implement proper solutions. This manual details all aspects of instrumentation of embankment dams and levees, including the traditional geotechnical concepts that must be understood and the growing concerns of rehabilitation, replacement, and maintenance. New initiatives such as automation are covered, as well as features that influence the performance of embankment dams and levees. Information presented can be applied to abutments, foundations, and the reservoir rim. Topics include behavior of embankments and abutments; instrumentation concepts, objectives, and system design considerations; summary of measurement methods; automation considerations; installation; data management, analysis, and reporting; instrumentation maintenance; and continual reassessment for long-term monitoring.
