Hamilton flood map Tasmania

Riverine flooding is a risk

  • in the townships of Bothwell, Hamilton, and
  • in the surrounding areas and roadways.

This area responds rapidly to rainfall.  Flash flooding often occurs in the steep upper sections and narrow valleys of the Clyde River. Flooding can last for hours or days, depending on rainfall.

The main areas at risk of inundation during a moderate to major flooding event in Bothwell are around

  • Arthur Crescent,
  • Nant Lane,
  • High Street and
  • William Street.

Properties in the east of the town may flood between

  • Patrick Street and High Street, and
  • High Street and Franklin St.

Clyde River flooding may cut the Highland Lakes Road.

In Hamilton, the showgrounds are likely to flood.  The Lyell Hwy may flood towards Ouse, including the bridge over the Clyde River. Sections of Hollow Tree Road between Hamilton and Bothwell may flood. Depending on where the rain falls and how heavy it is, Dennistoun Rd and other minor roads may flood and so be impassable for a short time.

The maps in this guide show flooding that has a 2%, 1% and 0.5% chance of happening any year (known as the Annual Exceedance Probability or 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 or heard about.

Even if your home is not inundated, you should prepare 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 or elsewhere, it is usually best you stay where you are until the flooding subsides, unless you are in danger. If you need to evacuate, you should leave early, before flood waters rise. Never drive through floodwater.

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

您有洪水风险吗？

The Clyde River has a long history of flooding, including in January 2011 when prolonged heavy rainfall caused major flooding, with widespread damage to roads, bridges and homes, and disruptions to essential services including power and water.

The Bureau of Meteorology has records of flooding in the Clyde River in 2009, 2001, 1960, 1931, 1929, 1923, 1922, 1910 (when half the bridge washed away in Hamilton),1905, 1903 and 1880, in all months of the year.

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。.
  • 准备家庭应急计划。考虑是否需要在洪水来临前撤离。参见 做好应急准备 – 个人和家庭应急准备指南。.
  • 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。.

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。.

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 is expected in an area. The time between the warning and heavy rain occurring can vary from an hour to 24 hours or more.

Whenever rain that may lead to flooding along the Clyde River is expected, the Bureau will issue:

  • A Flood Watch – a “heads up” early advice of forecast weather that may lead to flooding
  • A Flood Warning – giving a prediction of when flooding is likely to develop at gauge locations and possibly forecasting the likely peak river level.  Warnings are updated regularly.
  • SES and the Bureau will issue warnings when the Clyde River reaches the following levels.

A Flood Watch – a “heads up” early advice of forecast weather that may lead to flooding

A Flood Warning – giving a prediction of when flooding is likely to develop at gauge locations and possibly forecasting the likely peak river level.  Warnings are updated regularly.

SES and the Bureau will issue warnings when the Ouse and Derwent Rivers reach the following levels.

River gauges Alert Minor Moderate Major
Clyde River at Bothwell 0.9m 2.0m 3.0m 4.0m
Clyde River at Hamilton 2.4m 2.4m 3.5m 4.5m

There are no formal warning levels for other waterways in the area as the river systems are too short.

降水观测 at Bothwell, Ouse, Interlaken and Liaweenee 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 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。.

观察并行动（橙色）： 威胁级别有所提高。情况正在变化，您需要立即开始采取行动来保护您和您的家人
紧急警报（红色）： 紧急警报是最高级别的警报。您可能面临危险，需要立即采取行动。任何耽搁都可能危及您的生命。. 
社区更新（蓝色）： 关于特定事件或事件，受影响社区的具体信息和最新动态。.
事件（白色）： 事件是指在成为紧急警报之前的初次发生。一旦报告了事件，TasALERT 就会发布基本信息，包括事件的类型和地点。.

洪水水位

While no two floods are the same, the following describes what you can expect at different flood levels around the area. Even if your property is not flooded, you need to think about access. Different levels of rainfall can cause flooding depending on its intensity, duration and how wet the ground is beforehand and where the rain falls.

Clyde River Flooding

轻度洪水

A minor flood can inundate low lying paddocks.  Stock should be moved for their safety. Think about equipment such as pumps in these areas.  There may also be some flooding across minor roads, low bridges and parkland areas. Riverside areas like the Hamilton Campground may also flood.

中度洪水

In addition to the above, moderate flooding will be more extensive. Agricultural land and some buildings may flood to above-floor-height. Some properties may be isolated for a few hours as some roads become flooded.

特大洪灾

When the Clyde and its tributaries are in major flood, multiple properties and roads in Bothwell and Hamilton and surrounding areas are likely to be inundated and isolated. Some areas may need to evacuate. Extensive rural areas will flood, and major traffic routes may be closed. Services like electricity, water and sewerage may be cut for some time.

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。.

See for example the Huon Valley Good Neighbour project.

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。.
  • 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。.

免责声明

地图显示了集水区面临持续降雨的潜在洪水风险，例如%年一遇（AEP）的降雨。在洪水事件中，降雨在集水区内可能更不均匀，因此这些洪水地图仅供参考。已标绘的洪水风险区域表明被淹没的可能性较高。其他地区洪水风险较低，但在罕见且严重的洪水事件（%年一遇AEP的降雨概率更低）中，其他低洼地区也可能面临被淹没的风险。.
