Surveys were completed across and along the tops of the barrier beach as well as spot elevations of flood water and debris lines using RTK (Real Time Kinematic) GPS technology. Pre-hurricane surveys were available from all of the sites measured and efforts are now focussed on monitoring the recovery of the same shores at one-, six- and twelve- month intervals after the event. Information will be updated as subsequent surveys are completed. All elevations are relative to geodetic datum unless otherwise stated.

Une bonne part de la zone commerciale actuelle et la majeure partie de la zone résidentielle situées dans les plaines d'inondation seraient submergées, tout comme le serait l'ensemble des digues. Les documents historiques sur la tempête de Saxby font état que les eaux de crue sont demeurées piégées derrière les digues pendant plusieurs jours après la tempête.

During the Saxby Gale of 5 October 1869 a 2 metre storm surge coincided with the perigean spring tide. In this image, the blue colour shows the approximate area that would flood if these conditions re-occur. Much of the present commercial area and most of the residential area built on the flood plains would be submerged. All dykes would be overtopped. Historical documents on the Saxby Gale, report that flood water remained trapped behind the dykes for several days after the storm.

Une évaluation effectuée en 1996 chiffrait à 131 millions de dollars le coût des dommages que subirait Calgary lors d'une crue centenaire (crue qui a une chance sur 100 de se produire au cours d'une année donnée).

The risk of flood damage has been reduced by the construction of dams on the Bow River upstream from Calgary and of dikes around the floodplain areas of the city. However, the dams are too far upstream and the storage capacity of the reservoirs is too small to prevent the largest spring or summer floods. A 1996 estimate of the damage to Calgary resulting from a '100-year flood' (a flood that has 1 chance in 100 of occurring in any given year) is $131 million.

La crue est un processus naturel. Des inondations en résultent lorsque les cours d'eau débordent dans les basses terres environnantes. Les propriétés, les routes, les ponts et les voies ferrées situés dans ces terres inondables sont susceptibles d'être endommagés ou détruits par des niveaux d'eau trop élevés, ainsi que par de la glace en mouvement.

Flooding is a natural process. It happens when a river overtops its banks and inundates nearby low-lying areas. In communities built on these floodplains, properties, roads, bridges, and railways can be damaged or destroyed by high water levels and sometimes by moving ice. Floods can be caused by rapid melting of large amounts of snow, or rain on snow, or prolonged or torrential rainfall. Ice jams and landslide debris can also temporarily block a river, causing upstream flooding.

Le port de Halifax a enregistré un niveau d'eau record de 290 cm (zéro des cartes), ce qui a entraîné une inondation dévastatrice des propriétés du secteur riverain. À l'est de Halifax, à l'entrée de la baie Chezzetcook, les eaux de crue ont atteint une hauteur de 3,31 m (zéro des cartes) dans une maison.

Storm surge values ranged from around 1.0 metre (as far west as Mahone Bay) to 1.5 metres in Halifax Harbour (measured by a Canadian Hydrographic Service tide gauge) and possibly higher at the head of the estuaries east of Halifax. A record high water level of 2.90 m (chart datum) was recorded in Halifax Harbour which resulted in extensive flooding of the Halifax waterfront properties. East of Halifax, at the head of Chezzetcook Inlet, flood waters in a house reached an elevation of 3.31 m (chart datum).

En revanche, ils sont souvent le théâtre d'inondations et de coulées de débris. L'agglomération minière de Britannia, par exemple, a été dévastée par une crue soudaine le 28 octobre 1921. Celle-ci a été causée par un torrent catastrophique qui a détruit un remblai de voie ferrée retenant temporairement les eaux du ruisseau Britannia, après qu'un ponceau ait été bouché.

Debris fans are favoured sites for development because they are less steep than adjacent mountainsides. However, the fans are prone to floods and debris flows. The mining community of Britannia, for example, was devastated by a sudden flood on October 28, 1921. This flood occurred when a blocked culvert caused a railway embankment to temporarily dam Britannia Creek and then fail, releasing a catastrophic flood. A series of debris flows in the 1980s swept across debris fans north of Horseshoe Bay, destroying bridges and homes and claiming 11 lives. Zoning regulations now restrict development on hazardous fans. Where existing development is threatened, it can be protected by dams or deflection barriers, and by deepening and lining stream channels. Over $15 million was spent on protective works along Highway 99 following the disasters of the 1980s.

Bien que leurs réservoirs soient trop petits pour régulariser le débit de crue, les nombreux barrages hydro-électriques sur la rivière des Outaouais peuvent servir à informer les agglomérations en aval sur les dangers d'inondation.

Flood damages can be reduced substantially by avoiding development on flood-prone lands. Parks (such as Brewer Park along the Rideau River and Leamy Park in Gatineau) playing fields, and natural areas are appropriate land use for these flood-prone areas. Dikes, elevated embankments that provide a physical barrier between low-lying land and the river, can protect developments on the floodplain. A dike along the Gatineau River protects part of Gatineau. Although the reservoirs are too small to control flood discharge, the many power dams along the Ottawa River can alert downstream communities of potential flood conditions.
