Programme overview
Introduction:
Dam safety and dam engineering, covering inspection, monitoring and emergency action plans, is a five-day course for dam owners, water authority engineers, operators and consultants, ending with a Dam Safety Inspection Report and Emergency Action Plan outline for a case embankment dam. Many dams run for years on unread instrument readings, untested spillway gates and emergency plans never exercised, so seepage, erosion and overtopping warnings go unnoticed. Nominees already operate, inspect or oversee dams and work through an inspection walkthrough of dam records, photographs and monitoring data. CoreConcept Training Center delivers this course on dam safety.
Course Objectives:
- Classify embankment, concrete gravity and arch dams by structural behaviour, failure modes and downstream hazard potential
- Check spillway discharge capacity and energy dissipation against the inflow design flood and judge seepage and filter performance in embankments
- Plan and conduct dam safety inspections and rate the condition of the crest, slopes, spillway, gates and outlet works
- Interpret piezometer, settlement, deformation and seepage weir data against alarm thresholds to detect developing problems
- Lead periodic dam safety reviews and prioritise remedial works, gate maintenance and flood operation rules using risk-informed methods
- Prepare a Dam Safety Inspection Report and Emergency Action Plan outline with breach inundation, alert levels and a notification flowchart
Target Audience:
- Dam owner engineering teams accountable for the safety of dams and reservoirs in their portfolio
- Water authority engineering teams that oversee dam operation, maintenance and flood release decisions
- Dam operation and maintenance teams responsible for gates, outlets, surveillance rounds and instrument readings
- Dam safety consultant teams that carry out inspections, safety reviews and risk assessments for owners
- Emergency planning liaison teams that prepare downstream warning and evacuation arrangements for dams

Skills You Will Gain:
- Dam Failure Mode Identification
- Spillway Capacity Assessment
- Seepage and Internal Erosion Evaluation
- Dam Condition Rating
- Instrumentation Data Interpretation
- Dam Risk Prioritisation
- Gate and Outlet Maintenance Planning
- Dam Emergency Preparedness
Why Attend This Course:
- Deliver a Dam Safety Inspection Report and Emergency Action Plan outline to the dam owner's safety manager and the emergency planning committee
- Decide when an instrument trend, wet spot or gate defect calls for intensified monitoring, reservoir drawdown or an emergency alert
- Avoid overtopping, uncontrolled seepage and delayed downstream warning caused by untested gates and unread monitoring data
- Share inspection checklists, condition rating scales and alarm threshold sheets with operators who carry out routine surveillance
Conclusion:
Back at work, the participant gives the dam owner's safety manager and the emergency planning committee a Dam Safety Inspection Report and Emergency Action Plan outline for a dam in the portfolio. Managers use the report to fund remedial works, set monitoring frequencies and confirm gate testing, while the emergency plan guides alert decisions and downstream notification. After the first flood event or exercise, the unit should review whether alarm thresholds triggered correctly, whether contact lists worked and whether register deficiencies were closed on time.
Frequently Asked Questions (FAQ):
What should participants know before a dam safety and dam engineering course?
Participants should already work on the operation, inspection or oversight of dams or reservoirs and read basic engineering drawings. Bringing recent inspection notes, instrument readings or an existing emergency plan helps them apply the case work to their own dams.
How does dam safety and dam engineering differ from a geotechnical investigation or concrete repair course?
It concentrates on whole-dam safety management: failure modes, spillway capacity, surveillance, instrumentation, safety reviews and emergency planning. Geotechnical investigation courses cover soil testing for new works, and concrete repair courses cover fixing concrete members, which this course touches only briefly.
Why is internal erosion a major concern in dam safety and dam engineering?
Internal erosion can progress inside an embankment or its foundation with little visible sign until a breach develops. Rising seepage, turbid flow, sand boils and sinkholes are the usual warnings, which is why filters, drains, seepage weirs and frequent surveillance matter.
What do participants take back from the dam safety and dam engineering course?
Participants take back a Dam Safety Inspection Report and Emergency Action Plan outline built on a case embankment dam, with inspection checklists, a condition rating scale, instrument alarm threshold sheets and a notification flowchart to adapt for their own dams.
