Right tributaries Waiau River (Hawke's Bay)

The Wairoa River is a river in the Wairoa District on the North Island of New Zealand , whose catchment area with all its tributaries and tributaries includes almost the entire Wairoa District.

The name wairoa should literally mean "long river", but cannot be found in the Māori Dictionary.

geography

Following the official name of the river, the Wairoa River only begins at the confluence of the Ruakituri River with the Hangaroa River in the valley of the Te Reinga settlement , about 27 km northeast of the district capital Wairoa . From there, the Wairoa River flows in a south-westerly direction to Frasertown , and then flows further south with the inflow of the Waiau River towards Wairoa and then flows into Hawke Bay in an eastward arc . Before the Waiau River flows into the Wairoa River, it has taken in the tributaries of the Waikaretaheke River , which originate from Lake Waikaremoana . The entire catchment area of ​​the Wairoa River thus amounts to around 3,780 km².

Floods

Wairoa River, well filled, after rains in the mountains. View from the Wairoa Bridge in west direction.

The plain in the estuary of the Wairoa River is quite narrow compared to its catchment area, and in addition, the river estuary is constantly changing over a coastline of a good 2 km in length and can temporarily lead to poor drainage into the Pacific Ocean . In the months of November to April, the east coast is hit by more or less strong cyclones , some of which bring heavy rainfall with them, which can swell the rivers in a very short time and lead to significant flooding.

The city of Wairoa, which was built on the alluvial land of the Wairoa River, is in constant danger of flooding. In May 1948 heavy rainfalls brought 11,440 m³ / sec. the highest flow rate ever measured in New Zealand. The only bridge that connects the two districts of Wairoa with each other disappeared almost 1 m deep in the river. In 1988, however, the bridge was torn away by the effects of Cyclone Bora and the city flooded.
