Role of Instrumentation in a Dam Safety Program
This Workshop includes presentations, exercises, and instrumentation equipment displays/demonstrations which all are intended to provide workshop participants with improved insight, understanding, and comfort with respect to instrumentation.
The Workshop aims to cover a variety of topics related to dam instrumentation monitoring. Attendees will learn the fundamentals, what questions need to be answered by an instrumentation system, considerations to remember when evaluating the data, how does automation improve monitoring program, and be exposed to emerging technologies.
Workshop exercises will allow discussion of real-world scenarios. The scenarios will involve both embankment and concrete dams, planning of instrumentation system as well as data evaluation. A significant portion of the instrumentation workshop will be devoted to hands-on exercises design to walk participants through the entire scope of instrumentation from planning to design to evaluating data.
Instrumentation equipment suppliers will have displays that will be used to enhance the "foundational" presentations, and the workshop will offer time for one-on-one discussions with equipment suppliers regarding general or special questions, issues, challenges, etc.
Fundamentally, the Workshop will seek to maximize the opportunities for educational discussions among the participants, presenters, and instrumentation equipment suppliers about real-world situations, and how they might best be addressed.
The workshop will provide a general overview for the understanding of the factors that influence the accuracy and reliability of dam instrumentation data. Novice to seasoned professionals will all benefit from the workshop. Engineers, dam owners, geologists, technicians, and government agencies should all attend.
