Emu River

If there is heavy sustained rain, Emu River may flood its surrounds in Wivenhoe, particularly when tides are high.

• Businesses located south of the TasRail line are most likely to be inundated.
• Fern Glade parklands may flood.
• River Road may become impassable and isolate some businesses until river levels drop.
• Debris may build up around water crossings, including the rail bridge and fuel/gas pipeline. If this happens, these water crossings may be closed for safety reasons.

Flash flooding can affect across Wivenhoe and along the Emu River. Flash flooding means there can be little specific warning beyond forecasts for heavy rain or severe weather.

The maps in this guide show the level of flooding that has a 1% chance of happening any year (1% Annual Exceedance Probability (AEP)). You are likely to experience flooding such as that shown in the maps in your lifetime. Tasmanians need to prepare for flood events that may not happen often as well as the minor flooding they may have experienced.

Even if your business or home is not inundated, you should be prepared for isolation plus potential power and telecommunications outages.

Travel in the area is likely to be difficult or impossible until roads are clear.  If you are safe at home, your work or elsewhere, it is usually best you stay where you are until the flooding subsides, unless there is an emergency. If you need to evacuate, you should leave early, before flood waters rise.

If the Wivenhoe area is at risk of flooding, there is likely to also be flooding in surrounding areas. This may impact your employees, and their ability to work for you during the flooding event. 

If you own or manage a business, you should have an emergency plan that covers floods.  This can help you to reduce your losses from flooding and other emergencies. It can also help you to continue operating during and after a major flood. Business Tasmania has resources and support to help – see: www.business.tas.gov.au/managing/risk_management.

您有洪水风险吗？

Past flooding events around Wivenhoe include:

• 1929 – Bass Highway & Fern Glade Road bridges were washed away. There was significant debris at Railway Bridge.
• 2011 – Fern Glade Road bridge was severely damaged. Low-lying properties in River Road were flooded. There was again a lot of debris at Railway Bridge
• 2016 – Widespread inundation of River Road industrial area, caused significant economic loss. Debris such as trees and branches at railway bridge impacted nearby assets.
• 2022 – Significant inundation of low-lying properties in River Road. There was again woody debris pushed against Railway Bridge.

As an example, the 2016 widespread flooding of the River Road industrial area caused

• significant economic loss to local businesses, and
• the wider effects of disruption to business activity.

我应该怎么做？

• Check the map to see whether your business could flood.
• Assess your business premises and prepare it to minimise possible flood damage.
• Determine if your employees can safely access the workplace during a flood event.
• Prepare a Business Emergency Plan and Business Continuity Plan to ensure operational resilience.
• If your business relies on supply chains or customer access, consider early closure and evacuation, with alternative solutions to minimise disruptions.

Floods like the one shown in the maps, or worse, will occur again. No two floods are the same. If your business is in a low-lying area or near a watercourse, it may be at risk of flooding. Even if your premises are not directly impacted, road closures and infrastructure damage may impact your operations. Never drive into or enter flood waters. Roads and bridges may be washed out or unsafe. Avoid travel during floods.

Understanding your flood risk and preparing in advance can help protect your business assets and employees. Having a Business Emergency Plan is one of the best ways to prepare. Decide on weather and rainfall triggers for when to act.

澳大利亚气象局天气预报、警告和观测

The Emu River catchment has no formal flood warnings or flood classification levels. The river catchment is too short to give timely warnings based on river rises.

Whenever 大雨 is expected in an area that may lead to flooding, the Bureau issues

• Severe Weather Warning, and/or
• Thunderstorm Warning for heavy rainfall that may lead to flash flooding.

The time between the warning and heavy rain falling can vary from an hour to 24 hours or more.

降水观测 at Burnie (Park Grove) and Yolla and other nearby rain gauges can indicate possible flood risks. Given the very short warning times, it is best to act on the BoM warnings rather than wait for specific flood alerts during rainfall.

这 N.W. Tasmania (West Takone) radar is useful to be aware in real-time where heavy rainfall is falling.  Radar Rainfall estimates can also fill in gaps in areas where there are no rainfall stations.

洪水水位

While no two floods are the same, the following describes what is likely to happen if there is flooding around the area. Even if your property is not flooded, you need to think about access.

The rainfall amounts that might cause such an event are examples. Other levels of rainfall can cause flooding depending on

• where the rain falls
• how heavy the rain is
• how long the rain lasts, and
• how wet the ground is beforehand.
• Melting snow can also contribute to flooding.

Minor flooding (5%-10% chance annually)

• Some low-lying businesses and parkland along River Road may experience flooding.
• Parts of River Road may have minor water accumulation but remain passable.
• Heavy rain may lead to localised stormwater runoff affecting business premises.

Moderate Flooding (2%-5% chance annually)

• River Road may become impassable.
• More low-lying businesses along River Road may experience significant flooding.

Major Flooding (1% chance annually – comparable to 2022 floods):

• River Road will be inundated, isolating surrounding commercial properties.
• Businesses in reclaimed or low-lying areas may experience above-floor flooding.
• Flooding may extend to Fern Glade Reserve and Fern Glade Road.

Emu River flooding

Depending on where the rain falls and the tide level, major flooding is likely to inundate

• River Road roadway, isolating surrounding properties
• Commercial properties above floor level, particularly those in the low-lying and reclaimed areas along River Road
• Fern Glade Reserve and Fern Glade Road

Flooding from other waterways

If there is heavy local rainfall, there can be flash flooding around.

• Old Park River and Pet River (Emu River tributaries)
• Other low lying areas of Wivenhoe

了解风险，做好准备，尽可能降低风险，与他人联系，保持警惕，并安全行事。.

洪水之前

了解您的风险

塔斯马尼亚州经常发生洪水，可能造成广泛而重大的损失。在过去的 200 年里，塔斯马尼亚州有 78 人死于与洪水有关的事故。本指南旨在帮助您了解您所在地区的洪水风险。.

2. 准备您的家庭

制定涵盖风暴和洪水的应急计划

考虑一下在风暴或洪水来临时你会怎么做，这意味着你会有更好的准备，每个人都会更安全。制定一个你的家庭成员都明白的应急计划。有一些清单可以帮助你完善你的计划——请看 做好应急准备 – 个人和家庭应急准备指南。. 

定期检查您的计划，并让家中的每一位成员都模拟可能影响您家庭的洪水场景进行演练。.

准备一个应急包

准备好了

• 电池供电的收音机和手电筒，备用电池
• 重要信息，例如您的应急计划
• 紧急电话号码列表
• 食物和水
• 急救箱
• 橡胶或结实的皮革手套

视情况打包

• 保暖衣物、结实的鞋子或靴子
• 药品、眼镜或其他必需品
• 手机和充电器
• 宠物食品以及它们所需的其他任何物品
• 照片和特别的纪念品
• 钱
• 重要文件，例如

5. 保持更新

留意周围发生的事情。定期查看预报、观测和警报。. 

• 塔斯警报 
• 您当地的ABC广播电台 或
• 这 气象局 网站.

6. 确保安全

• 看管好孩子。.
• 为应对可能的电力、供水或网络中断做好准备。.
• 检查您的应急包是否已准备好。.
• 避开积水区域，如排水沟。. 永不 在洪水期间徒步、玩耍、骑车或驾车。您无法分辨水下有什么，也无法判断水深或水流速度。在仅 20 厘米的快速流动的水中，很容易被冲走并溺水。洪水可能很危险。.

当地面发生洪水时

• 将家用物品放在高处以最大程度地减少可能的损坏。.
• 如果安全的话，请关闭水电煤气。. 
• 一种防止污水倒灌回家的好方法是将沙袋放入塑料袋中，然后用它们堵住马桶、覆盖排水管和水槽。.
• 趁还能安全离开就走。.

如果您需要撤离

• 遵循 SES / 塔斯马尼亚警方 的建议。.  
• 带上你的应急包。. 
• 去安全地点或避难中心与亲友会合。. 
• 让别人知道你去了哪里。.

照顾好您的动物

在紧急情况下，您有责任照顾好您的动物。如果您有宠物和其他动物，在洪水或其他紧急情况下疏散需要更长的时间。在洪水可能上涨之前，将牲畜转移到易受洪水影响的地区。欲了解更多信息，请参阅

• RSPCA 应急动物准备指南
• 休恩谷委员会关于准备紧急宠物计划的建议
• 这 初级生产者农场防洪准备工具包.

避免在风暴期间和风暴过后出行

• 不要去观光。游客会延误紧急服务并造成事故。.
• 注意诸如
  • 路面积水
  • 受损的电力线
  • 山体滑坡
  • 损坏的道路
  • 倒下的树木或屋面板。.
• 切勿冒险涉水。洪水中的大多数死亡和救援事件都与驾车涉水有关。.
• 在未受洪水影响的路段，请慢行并打开车头灯。.

之后

• 请继续收听 ABC 本地广播电台的最新消息、道路重新开放信息、社区会议等。.
• 如果您离开了家，在紧急事务管理署（SES）或塔斯马尼亚警方告知您可以安全返回之前，请勿回家。.
• 注意道路危险，例如路面上的泥土或碎屑、损坏的道路/桥梁以及正在进行清理和维修的工作人员。.

如果您的房屋遭到损坏

• 在检查损坏时，请留在地面。注意倒下的树木、碎玻璃、松动的屋顶或其他危险。.
• 穿结实的靴子、手套和防护服。. 
• 在受洪水影响的建筑物内部，请使用手电筒，切勿使用火柴或蜡烛。. 
• 饮用水必须煮沸，直到被告知自来水安全为止。.
• 在经过持证电工或燃气技师安全检测前，请勿开启电源或燃气。.
• 如果您的房屋受损，需要住到别处，请带上您的应急包和宠物。
• 如果安全，请拍摄任何损坏的照片并联系您的保险公司。.
• 看管好孩子。.
• 检查邻居是否安好。.

The maps show potential flooding risks from consistent levels of rainfall across catchments, such as a 1% Annual Exceedance Probability (AEP).  In flooding events, rainfall is likely to be more inconsistent across a catchment, so these flood maps should be considered indicative only.  The mapped areas of flood risk show higher probability of inundation. Other areas have lower probability of flooding, but in severe and rare events (rarer than 1%AEP), other lower areas may be also at risk of inundation.
