Answer 1

Explanation:

Heavy rainfall can lead to numerous hazards, for example: flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure.More heavy rain is one of the hallmark signs of climate change. As the atmosphere warms, more water evaporates from soils, plants, lakes, and oceans. For every additional 1°F of warming, the atmosphere is capable of holding an additional 4 percent of water vapor. So when this additional water vapor condenses into precipitation, it leads to heavier rain — or when cold enough, heavier snow. Transport networks underpin economic cities competiveness and society functioning.

•

During flooding transport infrastructure can be directly or indirectly damaged.Existing approaches to assessing the impact of flooding on transport disruption do not capture the complexity of interactions between the flood hazard and transport system. Typically, assumptions can includebdiversion routes, and changes (or not) to driver behaviour as a result of the flood, are often assumed without any clear rationale

Answer 2

In New Zealand, heavy rainfall is relatively common. Often, a significant amount of precipitation occurs in only a few hours, leading to severe flooding and landslide risk.

Causes of heavy rainfall

Heavy rainfall occurs over New Zealand mainly because of the following common weather systems:

ex-tropical cyclones

North Tasman Sea lows moving to NZ region

depression/lows from the south

cold fronts.

New Zealand's mountains tend to modify and amplify precipitation, and this often causes the frequent heavy rainfall we experience. Heavy rainfall tends be most common over the western coastal region of the South Island and the middle and upper North Island, and least common on the east side of the South Island (due to the prevailing westerlies).

Potential consequences of heavy rainfall

Heavy rainfall can lead to numerous hazards, for example:

flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock

landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure.

Where heavy rainfall occurs with high winds, risk to forestry crops is high.
