Dam safety and integrity reports

Detects dam safety and integrity engineering reports: dam safety review, surveillance or inspection report wording with instrumentation readings (piezometers, seepage weirs, survey marks, reservoir levels) and located condition findings (seepage, cracking, erosion at the toe, spillway or abutment). Distinct from the referable-dam emergency action plan classifier, which covers EAP notification and inundation content. Topic wording alone is discovery-only.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: the topic phrase alone is discovery-only; enforcement needs populated structure (an instrumentation reading with units (piezometer, V-notch/seepage weir, inclinometer, settlement point, survey mark, reservoir level/FSL) or a located condition finding (seepage, cracking, erosion, slumping, settlement, spalling, scour, sinkhole, boil or piping at a chainage, toe, face, spillway, abutment, crest, gallery or outlet)), and 85 needs two distinct structures plus independent engineering-assessment (remedial works, risk rating, consequence category, dam safety engineer, recommendations) evidence, so policies, blank forms and training text stay below 75.
Detection quality: Topic false positive

Annual dam safety inspection report - Harbour Creek Dam Seepage observed at the downstream toe near chainage 420 m. — Medium-tier probe (75) - located condition finding
Dam surveillance report - Harbour Creek Dam, Q3 2026 Piezometer P4: 112.4 mAHD (up 0.8 m since June) V-notch weir: 3.2 L/s Reservoir level: 98 % Finding 3: increased seepage and a wet area on the downstream toe at chainage 420 m; longitudinal cracking on the crest near the left abutment. Recommendation: urgent geotechnical investigation and remedial works; dam safety engineer to confirm risk rating. — High-tier probe (85) - several instrument readings, located findings and engineering-assessment context

Known false positives

ANCOLD guidelines and dam engineering courses describe seepage and piezometers. Mitigation: Guidance/training framing is excluded; 85 needs two readings, a located finding and engineering-assessment context.
Referable-dam emergency action plans. Mitigation: Covered by au-qld-referable-dam-emergency-action-plan; this pattern needs engineering condition content.
