介绍

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 the Invermay and the Inveresk areas and provide you information on what you can do to prepare for, respond and recover from a major flood.

The maps at the start of this document are there to provide an understanding of the impact of a major flood in the Invermay and Inveresk area should the flood levee’s fail or overtop.

Overview

Invermay and Inveresk are one of the most flood prone areas in Tasmania, being on a floodplain at the junction of 3 major rivers:

• the South Esk River
• the North Esk River and
• the kanamaluka / Tamar River estuary.

Major flooding of the South Esk River is the greatest risk to Invermay, with a combined South Esk and North Esk Rivers flood event increasing the risk to the area.

Levees help protect properties around Invermay. However, there is no guarantee they can withstand a major flood.

Experiences in other countries show that levee failures can be gradual or sudden. Low lying parts of Invermay may flood quickly. Flood waters may isolate other areas of the suburb.

If the levees failed, people’s lives could be at risk in Invermay as evacuation would be difficult. Roads in and around the suburb will be closed due to the levee. Some other routes around Launceston may also be flooded. There will be long traffic delays. Isolated areas would probably not have services such as power, water and sewerage.  These may take some time to restore after a major flood.

The State Emergency Service, Tasmania Police and the City of Launceston have worked to identify Critical Decision Points (‘Trigger Points’) for actions that will keep people safe in a major flood event. These are outlined further in this document.

If the South Esk River is predicted to reach a certain flood height, a Voluntary Evacuation may be declared, it is recommended that you go somewhere safer until the water goes back down. If the river reaches a higher level, a directed Mandatory Evacuation will commence.

If a Mandatory Evacuation is called, services such as electricity, water and gas will be cut off to reduce hazards and protect assets so services can be restored as soon as possible when flood waters go down. If you decide to stay you will not have any of these services in your house – it is much better if you leave and leave early. If you stay, you could put yourselves and others at risk.

如果你有宠物，如果可能的话，你应该带上你的宠物。.

如果可以，最好在房屋面临洪水风险时，去亲戚或朋友家更安全的地方暂住。如果您无处可去，很可能 evacuation centre opened at the Silverdome – 55 Oakden Road, Prospect Vale. Keep checking Tas ALERT or listen to ABC local radio during a flood event for important information.

SES, City of Launceston and Tasmania Police can also provide information on where to go and how you can get there.

In such flooding events, some areas outside of Invermay may also be isolated due to flooding of the low lying areas, roads may have flood waters across them. It is dangerous to drive through flooded roads, particularly in isolated areas. It is recommended to find an alternative route.

Traffic is likely to be heavy throughout the city as roads and levee gate closures restrict traffic movements, so the best option is to leave early and allow plenty of time to get to a safe place.

如果堤坝决口或被漫过，那些未在接到指示时及早撤离的人

• 将他们的生命和其他人的生命置于危险之中，因为一些建筑物和道路可能迅速被淹没，疏散路线被淹没，以及其他地区与援助隔绝
• 无法保证能够获得紧急服务，例如救护车、警察、消防或应急服务。
• 不能期望获得诸如电力、燃气、供水、排污或电信等服务
• 可能会接触到废水，因为污水系统将被水淹没而无法正常运行。.

Map 3: Evacuation routes to the Silverdome Evacuation Centre from the Inveresk/ Invermay area.

• Green route – via Wellington Street noting that this route closes early with levee gate closures at Charles Street bridge.
• 黄色路线 – 经惠灵顿街、韦斯特伯里路至奥克登路
• 红色路线 – 经惠灵顿街、米德兰高速公路（南出口）、巴斯高速公路并通往奥克登路。.

您有洪水风险吗？

% 年超值概率 (AEP) 洪水事件，在任何给定年份都有% 的发生几率。您一生中至少会遇到一次这种频率的洪水。.

自欧洲人定居以来，朗塞斯顿（Launceston）长期遭受洪水侵袭：

• 1852年、1863年和1893年是记录在朗塞斯顿的严重洪水事件。.
• 1929 was the most severe flooding recorded in modern history. Over a thousand homes and buildings were damaged, with some swept from their foundations. The two suspension bridges over the Gorge area were damaged. Four thousand people were evacuated from Invermay, Inveresk and Margaret Street areas. The 1929 floods provided incentive to build the levees. It was not until 1940 that Launceston recovered from the flood.
• 2016年——朗塞斯顿为应对重大洪水事件做好了准备，并关闭了部分堤坝。.$2.16亿英镑——如果之前的旧堤坝失效，那么此前对堤坝系统的升级工程将避免损失约.
• 2022年 – 朗塞斯顿险些遭遇重大洪水事件。.

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。.

• • 如果你是初级生产者， 农场防洪应急包 为洪水提供准备建议，以帮助保护您的企业和库存。.

• • If you run a business or other organisation, check out the Tasmanian Government’s Emergency Ready Business tool online

• • 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。.

• • 如果您在易发洪灾的地区露营，请务必随时了解情况，如果可能发生洪水，请及早转移到高地。.

像地图上显示的洪水，或者更糟糕的情况，将会再次发生。没有两次洪水是相同的。.

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。.

气象局（BoM）预报、警告和观测

英联邦发出 洪水观察 when predicted weather might cause floods for the North Esk River. A Flood Watch may:

• 特定区域，例如 南埃斯克河 集水区，或
• 概括为，例如，适用于 中部北方河流流域

物料清单问题 洪水警告 with specific flood heights for the South Esk River and North Esk River. Flood gauges along the rivers provide warnings of flood heights and the possible impacts in Launceston. Tides can also add to the flooding risk around Invermay.

关键决策点

The North Esk and South Esk rivers have pre-determined triggers for an evacuation to be declared. Tasmania Police and SES will issue the evacuation notice.

Evacuation triggers – Flood height and water volume flowing from the South Esk River at Trevallyn Pond

• Voluntary Evacuation – BoM Moderate Flood Warning – 130.16 mAHD or 1600 cumecs (m³/s)
• Mandatory Evacuation – BoM Major Flood Warning – 130.95 mAHD or 2250 cumecs (m³/s)

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.
