Coastal Inundation, riverine and direct rainfall flooding information for the suburbs of Geilston Bay, Lindisfarne, Rose Bay, Rosny, Montagu Bay, Rosny Park, Warrane, Mornington, Bellerive, Howrah and Tranmere

DRAFT version 0.1 September 2025 for community input – email ses@ses.tas.gov.au

Understand your flood risk and get ready

Hobart’s eastern shore has few natural waterways, but does have a large network of stormwater drains and culverts, and extensive urban development that will affect flooding.

In Rosny Park and Warrane, a major flood in the Kangaroo Bay Rivulet could flood properties and roadways and the Eastlands Shopping Centre. In Geilston Bay, Flooding in Faggs Gully Creek could cut

Geilston Bay Road, and
Geilston Creek Rd.

The maps in this guide show the level of flooding that has a 1% chance of happening any year from waterways and direct rainfall flooding. Intense rainfall can cause flash flooding.

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 home is not inundated, you should prepare for isolation plus potential power and telecommunications outages. The Tasman Highway may be cut at Warrane and Mornington. Depending on where the rain falls and how heavy it is,

South Arm Highway
Rokeby Road, and
South Arm Road

may also be impassable, as well as minor roads and streets. Travel in the area is likely to be difficult or impossible until roads are clear. 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.

Listen to ABC local radio 936AM for warnings and advice.

您有洪水风险吗？

There have been flooding events in this area. In 2011 very heavy rain brought widespread flash flooding. Areas behind beach dunes, such as Bellerive Beach and Howrah Beach have often flooded, such as reported in The Mercury in 1953. There are not many recorded incidents of riverine flooding in this area.

我应该怎么做？

查看地图，了解您的住宅或商家是否可能发生洪水。.
评估您的住宅或企业，并做好准备以最大程度地减少潜在的洪水损害。.
洪水期间，检查您是否能够安全地到达家、工作地点或学校。.
Prepare a Home Emergency Plan. See 做好应急准备 – A guide for individuals and households to prepare for emergencies – see ses.tas.gov.au.
如果您可能被隔离并且必须获得服务，您可能需要提早撤离。.

澳大利亚气象局天气预报、警告和观测

该局发布 特大暴雨预警，恶劣天气预警和/或雷暴预警，可能导致山洪暴发 每当大雨警告和暴雨发生之间的时间可从一小时到 24 小时或更长时间不等。.

There are no river gauges or formal flood warnings for the waterways in this area.

降水观测 at Hobart Airport, Hobart (Ellerslie Rd) and other nearby rain gauges can indicate possible flood risks. Given the very short warning times, it is best to act on the predictive BoM warnings rather than wait for any flood alerts during rainfall.

这 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.

理解警告和关键信息

留意周围发生的事情。定期查看预报、观测和警报。.

更多信息请参见 www.ses.tas.gov.au/warnings/ .

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

如果您住在低洼地区或靠近水道，您的房屋可能会被淹没。即使您的家是安全的，您也可能需要绕过洪水地区，或者您的道路通行可能会受到阻碍。切勿驾车进入或进入洪水区域。道路和桥梁可能被冲毁或不安全。请避免在洪水期间出行。.

了解该怎么做可以拯救你的生命并帮助保护你的财产。制定家庭应急计划是准备工作的最佳方法之一。决定天气和降雨触发条件，以便知道何时采取行动。.

洪水水位

虽然没有两次洪水是完全相同的，但以下描述了您在该地区不同洪水等级下可能遇到的情况。即使您的房产没有被淹没，也需要考虑通行问题。不同强度的降雨、降雨持续时间、地面预先的湿润程度以及降雨落点都会导致不同程度的洪水。.

轻度洪水

A minor flood can inundate low lying parkland, gardens, orchards and paddocks. Stock and equipment should be moved. There may be some flooding across low-lying minor roads. Stormwater systems may block and cause isolated areas of flooding.

中度洪水

There is more extensive flooding of streets and parks and some buildings may be impacted to above floor height. Some properties may be isolated for a few hours as minor roads become flooded. The carpark of the Eastlands Shopping Centre may begin to flood, and properties and sports fields along Kangaroo Bay Rivulet may flood.

Near Bellerive Beach and Howrah Beach, flash flooding may occur, especially at high tide.

特大洪灾

When major flooding occurs, extensive urban and rural areas are inundated. Many buildings – houses, businesses and facilities – may be affected above floor level, major traffic routes will be closed and areas will be isolated.

Major flooding in this area could include:

In Warrane and Rosny Park, the Kangaroo Bay Rivulet would flood nearby properties, the Eastlands Shopping Centre and the sports facilities south of Rosny Hill Road
In Bellerive, and to a lesser extent Howrah, properties close to the beach would be flooded if the rain falls directly on these areas
Geilston Bay Rd, Rosny Hill Rd and parts of the Tasman Highway would flood and impassable
Other locations may flood depending on where the rain falls and how heavy it is.

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
- 保险单据
- 护照和
- 出生证明

定期测试收音机和手电筒里的电池。.

3. 尽可能降低洪水风险

在购买、维护或开发房产时，请考虑风暴、洪水和其他危险。.
修剪或移除您家中、商铺上方或您物业附近电线上方的树木和树枝。.
保持雨水槽和排水沟畅通。.

4. 与他人联系

认识你的邻居并参与社区活动。一个联系紧密的社区在紧急情况下更安全、更有韧性，并且有助于每个人在事后更好地恢复。检查家人和邻居是否安全，是否了解正在发生的情况。.

于

5. Keep up to date

留意周围发生的事情。定期查看预报、观测和警报。.

6. Act Safe

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

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。.
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。.

Please Note

The maps in this plan show data from the Tasmanian Strategic Flood Mapping (TSFM) project. You can explore this data with the Flood Hazard Data layers on www.thelist.tas.gov.au.

Clarence City Council has detailed flood studies for these areas, see https://www.ccc.tas.gov.au/living/your neighbourhood/flooding/. CCC data includes climate change projections, shows flooding at more shallow depths and therefore the flood extents are considerably different and generally larger, than the TSFM extents shown in the maps below. This data is based on rainfall averages from the past.

免责声明

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.
