48. A dam safety review for a dam whose failure consequence category is equal to or greater than «moderate» must include; (1) checking the condition and behaviour of the dam by means of
(a) an inspection of every structural component;
(b) an analysis of the compiled results of every inspection carried out since the last safety review or, in the absence of such a review, during the period considered appropriate by the engineer in charge of the review;
(c) where applicable, a check of the instrumentation and an analysis of the readings since the last safety review or, in the absence of such a review, during the period considered appropriate by the engineer in charge of the review; and
(d) a check of the functionality and reliability of the discharge facilities;
(2) verifying the dam design by means of
(a) a reappraisal of the design criteria, namely, the data, assumptions and analysis methods considered at the time of dam design, in particular with reference to hydrology, hydraulics, structure, discharge capacity and flood routing; and
(b) a validation of the stability of the dam and foundation, including, if the engineer in charge considers it appropriate, geotechnical investigations and static stability calculations or, where required, pseudostatic or dynamic stability calculations, of the structure and foundation of the dam based on dam design criteria in use at the time of the safety review, establishing new safety factors. The validation includes, if the engineer considers it appropriate, a characterization of the dam materials.
(3) where applicable, checking the safety devices with which the dam is equipped, namely, emergency systems, emergency detector systems and back-up systems;
(3.1) analysing the topography of the reservoir rim;
(4) reviewing the dam’s classification; and
(5) reviewing the impounded water management plan, if such a plan is required under Subdivision 1 of Division III for the dam undergoing the safety review.
