Tasmanians need to prepare for flood events that may not happen often as well as the minor flooding they may have experienced.

If you live, work or often visit Sandy Bay or surrounding areas, it is important you understand what a flood can look like so you can prepare. There is likely to be a flood that causes significant damage in the area at least once in your lifetime.

When there is heavy intense rain the Sandy Bay Rivulet can flood low-lying roadways and properties around

• Lower Waterworks Road/ Lynton Avenue/ Davey Place
• Bottom of Pillinger Street/ Digney Street/ Fitzroy Place to Regent Street
• Sandy Bay Road near Dr Syntax / Jersey St area / Osborne St area
• Quayle Street / Balmoral Street area
• Marieville Esplanade and waterside areas.

Other minor waterways or overland flow can impact

• Lower Duke Street/ Sandy Bay Road / Margaret Street area
• Proctors Road/ UTAS Sandy Bay Campus
• Lambert Rivulet surrounds,
• Sandy Bay Road between Derwent Water Avenue and Ethelmont Road
• Lower Sandy Bay / Sandown Park/ Nutgrove area
• Sandy Bay Road to the north of Cartright Reserve
• Parts of Hobart are prone to flash flooding, depending on how rain falls across kunanyi/ Mount Wellington. This means there can be little warning before waterways flood.
• There can also be stormwater run-off in other places if there is heavy rain. This can be difficult to predict.
• Areas near the waterfront are also affected by tides and coastal inundation, especially around Marieville Esplanade.

Flooding can isolate properties for a short time, depending on where the rain falls and how heavy it is. Even if your home is not flooded you should prepare for

• isolation
• potential power and telecommunications outages.

Waterways in the area are short, so flooding is likely to be for hours rather than days after rain stops. If you are safe at home or elsewhere, it is usually best to stay where you are until the flooding subsides. If you need to evacuate, pick up children from school or travel for some other reason, you should do so early, before flood waters rise.

The maps in this guide show the level of flooding that has a 1% chance of happening any year (Annual Exceedance Probability (AEP)) due to riverine flooding from Sandy Bay Rivulet and nearby minor waterways.

Check TasALERT.com or listen to ABC local radio Hobart 90.5FM or 936 AM for warnings and advice.

Example past flooding events around Hobart include:

• May 2018 – The Southern Tasmanian Extreme Weather Event caused flooding around Hobart. There was 236mm of rain on Kunanyi/ Mount Wellington in 24 hours. 
• April 1960 – About 200mm of rain over 3 days and caused damage across Hobart.
• June 1947 – Two separate flooding events impacted the Hobart area.

Apa yang patut saya buat?

• 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 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 Bersedia untuk Kecemasan – 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.

Mengetahui apa yang perlu dilakukan boleh menyelamatkan nyawa anda dan membantu melindungi harta benda anda. Mempunyai Pelan Kecemasan Rumah adalah salah satu cara terbaik untuk bersiap sedia. Tentukan pemicu cuaca dan hujan untuk masa bertindak.

Bureau of Meteorology (BoM) Forecasts, Warnings, and Observations

Whenever heavy rain is expected in an area, the Bureau issues

• a Flood Watch
• Severe Weather Warning and/or
• Thunderstorm Warning for heavy rainfall that may lead to flash flooding.

The time between the warning and heavy rain falling can vary from an hour to 24 hours or more. It is best to act on the warnings from the Bureau of Meteorology rather than wait for local flooding alerts.

Tracking Rainfall on Kunanyi/ Mount Wellington can help predict flooding around Hobart. Go to www.bom.gov.au/tas/ .

The Mt Koonya Radar is useful to see when and where heavy rainfall is falling.

Flood levels

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
• how wet the ground is beforehand, and
• where the rain falls.

In minor flood events

• Riverine flood water and storm water run-off may reach some building floor levels and impact low-lying paths, parks and backyards.

Banjir sederhana

• May mean water starts to enter some homes and other buildings
• There may be water across some key routes, such as Sandy Bay Road and Churchill Avenue/ Regent Street.
• Traffic is likely to become gridlocked in these conditions.

A major flood event

• May be for example due to heavy rainfall in the river catchment of about
  • 17mm or more in half an hour
  • 36mm or more in 3 hours
  • 51mm or more in 6 hours (5% AEP @ Hobart)
• Is likely to cause flooding over major thoroughfares in places, cutting access in some places. Traffic conditions are likely to be difficult.
• May isolate many properties for short periods. Flooding should quickly dissipate once rain stops.
• May inundate many low-lying areas. Flooding is likely to be more hazardous around:
  • Lower Waterworks Road/ Lynton Avenue/ Davey Place
  • Bottom of Pillinger Street/ Digney Street/ Fitzroy Place to Regent Street
  • Sandy Bay Road near Dr Syntax / Jersey St area / Osborne St area
  • Quayle Street / Balmoral Street area
  • Marieville Esplanade and waterside areas.
  • Lower Duke Street/ Sandy Bay Road / Margaret Street area
  • Proctors Road/ UTAS Sandy Bay Campus
  • Sandy Bay Road between Derwent Water Avenue and Ethelmont Road
  • Lower Sandy Bay / Sandown Park/ Nutgrove area

• Sandy Bay Road to the north of Cartright Reserve
• May include storm water run-off impacting other areas.
• Increase landslip and coastal erosion risks.

Weather systems causing such rainfall can also often cause coastal storm surge, particularly at high tide.

Know your risk, prepare, reduce risk where you can, connect with others, keep up to date and act safe.

Sebelum banjir

Ketahui risiko anda

Banjir sering berlaku di Tasmania dan boleh menyebabkan kerosakan yang meluas dan ketara. Dalam tempoh 200 tahun kebelakangan ini, terdapat 78 kematian berkaitan banjir di Tasmania. Panduan ini adalah untuk membantu anda memahami risiko banjir di kawasan anda.

TasALERT’s risk ready tool lets you check your property’s exposure to a range of hazards. See alert.tas.gov.au/get-ready/risk-ready/

2. Sediakan rumah anda

Miliki pelan kecemasan yang meliputi taufan dan banjir

Berfikir tentang apa yang akan anda lakukan semasa ribut atau banjir bermakna anda lebih bersedia dan semua orang lebih selamat. Miliki pelan kecemasan yang difahami oleh semua orang dalam isi rumah anda. Terdapat senarai semak untuk membantu anda memikirkan pelan anda – lihat Bersedia untuk Kecemasan – Panduan untuk individu dan isi rumah bersiap sedia menghadapi kecemasan. 
Periksa pelan anda dengan kerap dan uji ia dengan setiap ahli isi rumah memikirkan senario banjir yang mungkin menjejaskan isi rumah anda.

Sediakan Kit Kecemasan

Uji bateri dalam radio dan lampu suluh secara berkala.

3. Reduce your risk from flooding where you can

• Pertimbangkan tentang ribut, banjir dan bahaya lain semasa membeli, menyelenggara atau membangunkan hartanah.
• Potong atau alih pokok dan dahan yang menjulur ke atas rumah, perniagaan anda atau berdekatan talian elektrik di kawasan anda.
• Pastikan saluran air dan perparitan anda bersih.

4. Connect with others

Kenali jiran anda dan libatkan diri dalam komuniti anda. Komuniti yang saling berhubung adalah komuniti yang lebih selamat dan lebih berdaya tahan semasa kecemasan dan dapat membantu semua orang pulih dengan lebih baik selepas itu. Periksa sama ada keluarga dan jiran selamat dan sedar tentang apa yang berlaku.

Semasa

5. Sentiasa terkini

Sentiasa peka dengan apa yang berlaku di sekeliling anda. Periksa ramalan, pemerhatian dan amaran dengan kerap. 

• TasALERT 
• stesen radio ABC tempatan anda atau
• yang Biro Meteorologi laman web.

6. Bertindak Selamat

• Mengawasi kanak-kanak.
• Bersiap sedia untuk kemungkinan gangguan bekalan elektrik, air atau internet.
• Pastikan peti kecemasan anda bersedia untuk digunakan.
• Jauhi kawasan yang dinaiki air seperti longkang. JANGAN SESEKALI berjalan, bermain, menunggang atau memandu dalam air banjir. Anda tidak selalu dapat melihat apa yang ada di bawah air atau betapa dalamnya atau derasnya air itu. Sangat mudah untuk dihanyutkan dan lemas dalam air yang bergerak pantas sedalam 20sm. Air banjir boleh berbahaya.

Bila rumah anda mungkin dinaiki air

• Letakkan barangan isi rumah di tempat yang tinggi untuk meminimumkan kerosakan yang mungkin berlaku.
• Padamkan bekalan elektrik dan gas jika selamat untuk berbuat demikian. 
• Cara yang baik untuk menghentikan aliran kumbahan masuk semula ke rumah anda ialah dengan meletakkan beg pasir di dalam beg plastik dan menggunakannya untuk menyumbat tandas serta menutup longkang dan singki.
• Pergi selagi anda boleh keluar dengan selamat.

Jika anda perlu berpindah

• Ikuti nasihat dari SES / Polis Tasmania.  
• Ambil kit kecemasan anda. 
• Pergi ke tempat rakan atau keluarga yang lebih selamat atau pusat pemindahan. 
• Beritahu orang lain ke mana anda telah pergi.

Jaga haiwan peliharaan anda

Anda bertanggungjawab terhadap haiwan anda semasa kecemasan. Sekiranya anda mempunyai haiwan peliharaan dan haiwan lain, anda akan mengambil masa lebih lama untuk berpindah sekiranya berlaku banjir atau kecemasan lain. Pindahkan ternakan dari kawasan yang terdedah kepada banjir **jauh sebelum** paras air banjir mungkin naik. Untuk maklumat lanjut, sila lihat

• Panduan RSPCA untuk persediaan haiwan dalam kecemasan
• Nasihat Majlis Lembah Huon tentang penyediaan rancangan kecemasan haiwan peliharaan
• yang Primary producer farm flood readiness toolkit.

Avoid travelling during storms and after storms

• Jangan melancong. Pelancong melambatkan perkhidmatan kecemasan dan menyebabkan kemalangan.
• Berhati-hatilah terhadap bahaya seperti
  • air di atas jalan
  • talian elektrik rosak
  • tanah runtuh
  • jalan rosak
  • pokok tumbang atau bumbung besi.
• Jangan memandu melalui air banjir. Kebanyakan kematian dan penyelamatan dalam banjir disebabkan oleh orang yang memandu melalui air banjir.
• Pandu perlahan dan pasang lampu hadapan anda di jalan yang tidak dinaiki banjir.

Selepas

• Terus ikuti perkembangan terkini dari ABC Local Radio, pembukaan semula jalan, mesyuarat komuniti, dll.
• Jika anda meninggalkan rumah anda, jangan pulang ke rumah sehingga SES atau Polis Tasmania memberitahu anda selamat untuk berbuat demikian.
• Berhati-hatilah terhadap bahaya jalan raya, seperti lumpur atau serpihan di jalan, jalan/jambatan yang rosak dan kru yang sedang bekerja membersihkan dan membaiki.

Jika rumah anda rosak

• Tinggal di aras tanah semasa memeriksa kerosakan. Berhati-hatilah dengan pokok tumbang, kaca pecah, bumbung yang longgar atau bahaya lain.
• Pakai but kuat, sarung tangan dan pakaian pelindung. 
• Gunakan lampu suluh, jangan gunakan mancis atau lilin di dalam bangunan yang dinaiki banjir. 
• Rebus semua air minuman sehingga anda diberitahu air paip selamat semula.
• Jangan hidupkan bekalan elektrik atau gas sehingga ia diuji oleh juruelektrik atau pemasang gas bertauliah bagi memastikan keselamatan.
• Jika rumah anda rosak dan anda perlu menginap di tempat lain, bawa bersama kit kecemasan dan haiwan peliharaan anda
• Ambil gambar kerosakan jika selamat untuk anda berbuat demikian dan hubungi syarikat insurans anda.
• Mengawasi kanak-kanak.
• Periksa jiran dalam keadaan baik.

Penafian

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.

The information in this guide is current at the date of publication. While every effort has been taken to ensure the validity and accuracy of the data presented, the State Emergency Service does not take responsibility for data error or omission.
