Instrumentation and Performance Monitoring of Dams - Four Part Series


This webinar will include presentations which all are intended to provide viewers with improved insight, understanding, and comfort with respect to instrumentation. 

This webinar series will consist of four sessions.

  • Planning an Instrumentation Program
  • Installation of Dam Monitoring Instrumentation
  • Threshold Values and Action Levels
  • Evaluation of Data

The presentations will discuss both embankment and concrete dams with a focus on PFMA in defining monitoring programs, thresholds and action levels, and evaluation of data.

The panelists consist of representatives from owners, regulators, vendors, and consultants who will provide their perspective with regard to dam safety and the four topics above. The workshop sessions will be organized to allow for both panelist presentations and ample discussion and questions between attendees and the panelists.

This webinar series seeks to provide participants greater understanding about real-world situations, and how they might best be addressed.


Understand the purpose of a dam instrument monitoring program:     

  • Types of instruments and data collection alternatives
  • Use of data as input for Potential Failure Modes Analysis (PFMA) and risk analysis

Purpose of instrumentation with regard to construction monitoring, design verification, and general health monitoring

  • Understand key considerations for installation of instrumentation, including best practices and common sources of error.
  • Understand the role of thresholds and action levels and considerations to establish them.
  • Understand key considerations in data evaluations and project performance.

Encourage open discussions between panelists from across industry (i.e., owners, regulators, vendors, and consultants) and participants.

Target Audience

Novice to seasoned professionals will all benefit from the workshop. Engineers, dam owners, geologists, and technicians involved in dam safety should consider this webinar.
