您有洪水風險嗎？

Railton is at risk of flooding from high flows in Redwater Creek or from intense rainfall in the catchment, with the potential for greater impacts when the two occur together. Due to the rapid catchment response, flooding can develop quickly during rain events, causing serious impacts in the town.

What You Need to Know

• Flooding can cut off parts of Railton. It may be hard to leave or get help for some time.
• Floodwaters might divide the town. It may be difficult to reach evacuation centres or essential services.
• It may not be easy to move emergency supplies and sandbags once flooding starts and roads become cut.
• If flooding is likely, residents should take action early, such as sandbagging and moving to safety.
• There may be no warnings issued for flash flooding

When Could Flooding Happen?

• Flash flooding can happen with little warning, especially after heavy or ongoing rain.
• Flash flooding may begin 2 to 6 hours after significant rain.  

Who Is Most at Risk?

• People living in low-lying areas or near Redwater Creek.
• Residents who have moved to Railton more recently and may not be familiar with local flood risks.
• Older residents or those who need help with daily activities.

When to Act

You should act if the following rainfall is recorded at the Sheffield School Farm weather station:

• 20mm in 30 minutes
• 38mm in 1 hour
• 50mm in 3 hours

我應該做什麼？

Check the map to see whether your home or business is at risk of being flooded. If it is, you should have a plan for leaving during a flood event.

• Check if you can safely get to or from your home, work, or school during a flood. If you need to leave during a flood, make sure your route is safe or leave early before floodwaters rise. If you need to evacuate during a flood, make sure your route is safe and think about:
  • where you would go
  • how you could get there
  • what you need to take.
• Prepare your home or business to reduce possible flood damage.
• Prepare a Home Emergency Plan. See 為緊急情況做好準備 – A guide for individuals and households to prepare for emergencies . 
• If you have a business in the area, you should have a plan that covers flooding.  Business Tasmania can help– see www.business.tas.gov.au/managing/risk_management .  
• During a flood event, go to TasALERT.com or listen to ABC local radio to find out about evacuation centres or other places to shelter. 
• TasALERT’s risk ready tool also lets you check your property’s exposure to a range of hazards. See alert.tas.gov.au/get-ready/risk-ready/

Floods like the one shown on the map, or worse, will occur again. No two floods are the same.

If you live in a low-lying area or near a watercourse, your house may flood. Even if your home is safe, you may need to detour around flooded areas or your road access may be cut.

Never drive into or enter flood waters. Roads and bridges may be washed out or unsafe. Avoid travel during floods.

知道該怎麼做可以拯救你的生命並保護你的財產。制定家庭緊急計畫是最好的準備方法之一。決定天氣和降雨的觸發條件，以便採取行動。.

Railton’s past history of flooding

Railton has a history of significant flooding, including in 1876, 1894, 1929, 1970, 1973, 2011 and 2016.

The 2011 flood was similar in magnitude to an event with an Annual Exceedance Probability (AEP) of approximately 1%, meaning it has about a 1 in 100 chance of occurring in any given year. This event inundated 60 houses and 14 businesses, and caused widespread disruption to roads and streets throughout the town.

In past floods, people from Railton have been trapped by flood waters in their cars and on their house roofs. Flooding of Redwater Creek in Railton often occurs at the same time as flooding of other water courses in the area, including the Mersey River and the Dasher River. This means that the roads between Railton and other towns such as Sheffield and Latrobe can be flooded and damaged. Emergency Services from other towns may not be able to access Railton in a flood.

Flood levels at Railton

Severe Weather Warnings and Flood Watches can forecast the amount of rain likely in an area. See detailed rain forecasts for Railton on the MetEye page on the BoM website www.bom.gov.au/tas/forecasts/railton.shtml .

24 hour rainfall totals at Railton can help you estimate how much flooding could occur. Flooding can also occur if a large amount of rain falls quickly in a short time, or it rains for days in a row.

While no two floods are the same, the following describes what you can expect at different flood levels around Railton. Even if your property is not flooded, you need to think about access routes.

10% AEP (10% chance of occurring in any year)

Potential rainfall trigger: About 54 mm of rain in 6 hours @ Sheffield School Farm

What might happen:

• Around 80 homes and businesses could flood. This includes parts of Crockers Sr, Esplanade, Foster St, Giblin St, Kimberley Rd, Latrobe Rd and Morrison St.

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

Flooding often happens in Tasmania and can cause widespread and significant damage. In the past 200 years there have been 78 flood related deaths in Tasmania. This guide is to help you understand flood risk in your area. Familiarise yourself with evacuation routes or higher places that will be safer from flooding, noting a flood event in Railton is unlikely to last more than 12 hours.

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。.

Prepare and emergency kit

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. Keep up to date

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. Act Safe

• 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
• Huon Valley Council’s advice on preparing an emergency pet plan
• 這 主要生產者農場洪水準備工具箱

Avoid travelling during and after storms

• 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。.
• Do not turn on electricity or gas until it is tested by a licensed electrician or gas fitter for safety.
• 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。
• 如安全，請拍攝任何損壞的照片，並聯繫您的保險公司。.
• 監督兒童.
• 檢查鄰居是否安好。.

免責聲明

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.
