South Island

Comments:

CauseIt was a complex build-up to the heavy rain event. At noon on the 19th, two depressions lay in Tasman Sea, while warm air from the subtropics collided with cold sub-antarctic air. By the 20th, the two lows had combined into one deeper one and a strong baroclinic zone lay over South Canterbury. The intensification of an anticyclone to the south of New Zealand, bringing cold air northwards, and halting any southeastward movement of the low, was an important factor in producing extreme rainfalls. Convection must have been a major contributor.

ImpactPractically all low-lying areas were inundated.

Peak DischargeBalclutha had an estimated peak discharge of 95,000 cusecs (2690 cumecs).

CommentThere was a major flood in the Clutha River and Balclutha area.

Physical CharacteristicThe Clutha River level was 72.5 ft (22.1m) at the Balclutha traffic bridge.

CommentThere were several breaks in the stopbank around Balclutha. The worst break occurred at Stirling.

ImpactAt a break in stopbank, by the main highway connecting Kaitangata to Balclutha, river overtopped the bank, falling onto cultivated land. It caused scour, cut back towards river and collapsed the bank, connecting back up with river. Floodwaters poured through the gap at a rate of 13,000 cusecs (368 cumecs), flooding Stirling, Benhar, Lovells Flat and Kaitangata areas (an area of 35,000 acres).

Damage CostDamage in the Balclutha area totalled £121,000 ($8,100,000 2006 dollars). This included £70,000 ($4,700,000 2006 dollars) to farmers and £51,000 ($3,400,000 2006 dollars) to public works but not including damage to railways, coalmines, freezing works or dairy factories.

ImpactSeveral farmsteads at Inchclutha had water in the houses to depth of a few inches.

ImpactThere was minimal inconvenience at Balclutha caused by the flooding except that at south end. The low-lying paddocks were under water due to the lock at the outlet of the drainage creek not being closed in time.

SevereFebruary 1945 South Island Flooding ( 1945-02-19 )

80 years

Heavy rain caused widespread flooding over the South Island. The worst hit region was Canterbury where there was heavy losses of crops and severe damage to roads and railways.

South Island

Heavy RainHeavy Rain at South Island
Comments:

CauseIt was a complex build-up to the heavy rain event. At noon on the 19th, two depressions lay in Tasman Sea, while warm air from the subtropics collided with cold sub-antarctic air. By the 20th, the two lows had combined into one deeper one and a strong baroclinic zone lay over South Canterbury. The intensification of an anticyclone to the south of New Zealand, bringing cold air northwards, and halting any southeastward movement of the low, was an important factor in producing extreme rainfalls. Convection must have been a major contributor.
