Riverine flooding information for New Town Rivulet and its tributaries.

Parts of New Town and Lenah Valley are subject to flooding from New Town Rivulet or its tributaries such as Pottery Creek, Brushy Creek or Maypole Creek. You are likely to experience flooding such as that shown in the map at least once in your lifetime. See Hobart City Council’s flood mapping 或 Glenorchy City Council’s flood mapping for more detail.

Like most of Hobart, New Town and Lenah Valley are prone to flash flooding so there is often very little warning. As well as riverine flooding, there is also likely to be additional minor flooding caused by stormwater run-off. This can be difficult to predict.

Even if your home is not inundated, you should be prepared for isolation plus potential power and telecommunications outages. Flooding may isolate parts of Lenah Valley for up to 6 hours, depending on the rainfall across Kunanyi/ Mount Wellington.

Travel in the area is likely to be difficult or impossible until roads are clear and safe. In a major flooding event, roads in and around Hobart are likely to be cut as other areas of Hobart are inundated. Traffic is likely to be congested. If you are safe at home 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.

Go to tasalert.com.au or listen to ABC local radio 936AM for warnings and advice.

您有洪水風險嗎？

Example past flooding events around New Town / Lenah Valley include:

May 2018 – The Southern Tasmanian Extreme Weather Event caused flooding around Hobart. There was 236mm of rain on Kunanyi/ Mount Wellington.
April 1960 – About 200mm of rain over 3 days and caused damage across Hobart.
June 1947 – Two separate flooding events impacted the Hobart area.

What should I do to be prepared?

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. During a flood event, go to 塔斯警報 or listen to ABC local radio to find out about evacuation centres or other places to shelter.
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 safe and think about:
- where you would go
- how you could get there
- what you need to take.
Prepare your home or business to minimise possible flood damage.
Prepare a Home Emergency Plan. See 為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。.
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/manage_a_business/ .

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

如果您居住在低窪地區或靠近水道，您的房屋可能會被淹沒。即使您的住所安全，您也可能需要繞過淹水地區，或者您的道路通行可能會被阻斷。切勿駕車進入或身處洪水之中。道路和橋樑可能會被沖毀或不安全。洪水期間請避免出行。.

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。.

中央氣象局預報、警報與觀測

本局發佈 洪水警报、恶劣天气警报和/或雷暴警报，可能因强降雨引发山洪暴发 每當大雨 is expected in an area. The time between the warning and heavy rain occurring can vary from an hour to 24 hours or more.

雨量觀測 on Kunanyi/ Mount Wellington can help predict potential flooding in New Town and Lenah Valley, however, the warning times are very short. Hobart’s waterways are prone to flash flooding. Given the very short warning times, you are encouraged to act on the predictive BoM warnings rather than wait for any alerts during rainfall.

這 Mt Koonya 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.

Flood Warnings are expressed as Minor, Moderate, or Major.

Flood levels in New Town and Lenah Valley

While no two floods are the same, the following table shows what you can expect at different flood levels around South Hobart. Even if your property is not flooded, you need to think about access. The example rainfall to cause such an event is an example: other levels of rainfall can cause flooding depending on its intensity, duration and how wet the ground is beforehand and where the rain falls.

A Minor Flood (less than 20% chance of happening in a year (Annual Exceedance Probability – AEP)

For example up to about 50mm over 6 hours on Kunanyi/ Mount Wellington

As reclaimed land, parts of Lower Risdon Road/ the lower end of Albert Rd and the playing fields around Cornelian Bay, Queens Walk Oval and surrounds may be inundated. Use alternate routes.

Walking tracks along rivulets may become inundated.

A Moderate Flood (from a 20% and below a 1% chance of happening in a year)

For example about 50-80 mm in 6 hours on Kunanyi/ Mount Wellington

Low lying areas become inundated along waterways. Water may be above floor heights for some properties in areas such as

Augusta Rd
Forster St intersection with New Town Rd and near Valentine St
Bellevue Parade
Further areas of Risdon Rd
Lower Lenah Valley Rd
Kiewa Rise
Valentine St
Pedder St and Cross St
Mercer St cul de sac

Hobart City High School New Town Campus and New Town Primary School grounds likely to be inundated

There is likely to be water on many routes – see maps for details.

A Major Flood (a 1% chance or less of happening in a year in the current climate)

For example more than 80 mm in 6 hours or more on Kunanyi/ Mount Wellington

Those areas inundated in moderate flooding events will have higher water levels, above floor level in many cases. Further areas are likely to experience flooding and properties in these areas with low floor levels are likely to be impacted. Please refer to the maps for details on specific areas.

Some areas may become isolated for some hours, including Lenah Valley Road and surrounds.

Unless there is an emergency or you are not safe where you are, you should shelter where you are during a flooding event. Floods around Hobart rarely last more than a few hours. Traffic is likely to be very congested. Listen to ABC local radio or go to 塔斯警報 for advice.

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

重要文件，例如
– insurance papers
– passports and
– birth certificates

定期測試收音機和手電筒的電池。.

3. Reduce your risk from flooding where you can

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. Connect with others

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。.

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

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。.
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。
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.
