Dam inspection and condition assessment
Dam inspection and condition assessment is the periodic examination of existing embankment and concrete dams to detect deterioration, judge seepage and cracking, and re-evaluate safety.
Dam monitoring and instrumentation
Dam monitoring and instrumentation is the practice of measuring pore pressures, seepage, movements, and stresses to check that a dam in service is behaving as designed.
Dam removal

Dam Safety Guidelines (Canadian Dam Association)
The Dam Safety Guidelines of the Canadian Dam Association are the association's principal reference for good practice in managing dams safely in Canada, currently the 2013 edition.
Dam safety monitoring
Dam safety monitoring is the continuous or periodic observation of a dam's behavior through visual inspection and instruments measuring seepage, pressure, and movement, so defects are caught before failures.
Dam safety regulation
Dam safety regulation is the body of laws, agencies, and enforcement practices that assign responsibility for safe dam design, operation, maintenance, and inspection to prevent catastrophic failures.
Dam safety risk assessment
Dam safety risk assessment is the structured process of identifying potential dam failure modes, estimating their probability and consequences, and comparing the risks against tolerable-risk thresholds to prioritize action.
