2006 – Some Dam Monitoring Observations and Experiences from New Zealand

M Gillon, T Logan, N Logan

The paper has been prepared to support the key questions selected for the ANCOLD Dam Instrumentation and Survey Seminar to be held in Sydney in November 2006 and to provide a New Zealand perspective. The paper is not a ‘state of dam monitoring practice in New Zealand’ dissertation but is rather a targeted summary of the authors’ experiences and observations from practicing in this area.

These experiences and observations on dam monitoring are grouped under the following headings, reflecting the key questions:

• Dam monitoring in New Zealand
• Monitoring in the dam life cycle
• How much monitoring is enough
• Instrumentation and survey issues
• Using and managing monitoring data
• Some early warning examples
• Monitoring as part of remediation
