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.

您有洪水風險嗎？

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.

我應該做什麼？

• 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.

中央氣象局預報、警報與觀測

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.

雨量觀測 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.

這 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

了解你的風險，做好準備，盡可能降低風險，與他人聯繫，保持警惕並安全行動。.

洪水之前

1. 認識你的風險

塔斯馬尼亞經常發生洪水，可能造成廣泛且嚴重的損害。在過去 200 年裡，塔斯馬尼亞有 78 人死於與洪水相關的事件。本指南旨在幫助您了解您所在地區的洪水風險。.

2. 準備您的家戶

制定包含風暴和洪水應變計畫

思考一下在風暴或洪水來襲時你會怎麼做，意味著你準備得更充分，每個人都會更安全。制定一個家庭中的每個人都理解的緊急計畫。有檢查表可以幫助你思考你的計畫——請參閱 為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。. 

定期檢查您的計劃，並讓家中的每個人都設想一次可能影響您家的洪水情況來進行測試。.

準備一個緊急救生包

準備好了

• 電池供電的收音機和手電筒，備用電池
• 重要資訊，例如您的緊急應變計畫
• 緊急電話號碼列表
• 食物和水
• 急救箱
• 橡膠手套或堅固的皮革手套

需要時打包

• 暖和的衣服、結實的鞋子或靴子
• 藥品、眼鏡或其他必需品
• 手機和充電器
• 寵物食品和他們需要的任何其他東西
• 照片和特別紀念品
• 錢
• 重要文件，例如
  • 保險文件
  • 護照與
  • 出生證明

定期測試收音機和手電筒的電池。.

3. 在可能的情況下，降低您遭受洪水侵襲的風險

• 在購買、維護或開發房地產時，請考慮風暴、洪水和其他災害。.
• 修剪或移除您家中、商家或您家附近有電力線的樹木和樹枝。.
• 保持您的排水溝和排水管暢通。.

4. 與他人建立聯繫

認識你的鄰居並參與你的社區。一個緊密的社區，在緊急情況下更安全、更有韌性，並有助於每個人在事後更好地恢復。檢查家人和鄰居是否安全，並了解正在發生的事情。.

期間

5. 保持更新

隨時留意周遭狀況。定期查看天氣預報、觀測數據和警報。. 

• 塔斯警報 
• 您當地的 ABC 電台 或
• 這 氣象局 網站.

6. 保持安全

• 監督兒童.
• 為可能的停電、停水或斷網做好準備。.
• 檢查您的緊急救助包是否已準備就緒。.
• 切勿靠近淹水區域，例如排水溝。. 永不 在洪水中有行走、玩耍、骑行或开车。你無法確定水下有什麼，或水有多深、流速有多快。20公分的湍急的洪水就很容易將人沖走並淹死。洪水可能很危險。.

您的房屋可能發生淹水時

• 將家居物品放在高處，以盡量減少潛在損壞。.
• 如果安全的話，請關閉水電和瓦斯。. 
• 一種防止污水倒灌回屋內的好方法是將沙包放入塑膠袋中，然後用它們來堵塞馬桶、蓋住排水孔和水槽。.
• 趁你還能安全脫困時趕快離開。.

如果你需要疏散

• 請遵循 SES / 塔斯馬尼亞警方的建議。.  
• 帶上你的緊急求生包。. 
• 前往朋友或家人較安全的地方，或前往疏散中心。. 
• 讓別人知道你去了哪裡。.

照顧好你的動物

在緊急情況下，您有責任照顧您的動物。如果您有寵物和其他動物，在洪水或其他緊急情況下，疏散的時間會更長。在洪水可能上漲之前，請及時將牲畜移離易受洪水影響的地區。更多資訊請參閱

• RSPCA 應對緊急情況動物的指南
• 胡昂谷議會關於準備緊急寵物計畫的建議
• 這 主要生產者農場洪水準備工具箱.

請避免在風暴期間和風暴之後旅行

• 不要去觀光。觀光客會延誤緊急服務並造成事故。.
• 注意危險，例如
  • 路面积水
  • 損壞的電力線
  • 山崩
  • 損壞的道路
  • 倒下的樹木或屋頂鐵片。.
• 切勿駕車通過淹水區域。洪水中的大多數死亡和救援事件都與駕車通過淹水區域有關。.
• 緩慢行駛，並在不受洪水影響的道路上打開頭燈。.

之後

• 請持續收聽 ABC 地方電台的最新消息、道路重新開放、社區會議等資訊。.
• 如果您離開家，請勿在聯邦緊急事務局 (SES) 或塔斯馬尼亞警方告知您安全之前回家。.
• 注意道路上的危險，例如路面上的泥沙或碎屑、道路/橋樑損壞以及正在進行清理和修復工作的工人。.

如果您的房屋已受損

• 在檢查損壞時，請待在地面。小心掉落的樹木、碎玻璃、鬆動的屋頂或其它危險物品。.
• 穿著堅固的靴子、手套和防護服。. 
• 請使用手電筒，切勿在受洪水影響的建築物內使用火柴或蠟燭。. 
• 將所有飲用水煮沸，直到被告知自來水再次安全為止。.
• 在經註冊電工或燃氣技師測試安全之前，請勿開啟電力或燃氣。.
• 如果您的房屋受損，需要暫時住在其他地方，請攜帶您的緊急應變包和寵物一同前往。

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.
