Riverine flooding information for the South Esk River, Macquarie River and Back Creek

To see the maps in more detail, lihat Peta Banjir Strategik Tasmania.

Longford can have riverine flooding from the South Esk River, Macquarie River and Back Creek. The levee system was constructed to protect Longford and mitigate against rare flooding events of the South Esk River.

The map shows the expected Major Flood levels in the Longford region. This level of event has about a 1% chance of happening any year (1% Annual Exceedance Probability (AEP). You are likely to experience a flood of this size in your lifetime.

A 1% AEP event is the limit of flood mitigation provided by the Longford levee system. Above this level there will start to be flooding within the levee protected area.
In the event of levee gate closure at Tannery Road access to the north is closed, and some streets off Wellington Street to the east. This will include the installation of some temporary levee structures. An alternative flood access plan will become activated during a major flooding event.

During a Major flooding event there are three alternative routes that can be used according to the height of the floodwaters, and closure status of the levees:

• Route 1 (Green) – Before closure of Illawarra Road vehicles can travel out of Longford via Wilmores Lane (Opposite Austral Bricks), turn right onto Bishopsbourne Road and turn right onto Illawarra road towards Perth, or left to the Bass Highway. This route may be closed considerably earlier than the flooding risk by Tasmania Police.
• Route 2 (Purple) – When Illawarra Road to the east of the Longford town entrance becomes closed, vehicles can travel out via Wilmores Lane, turn right onto Bishopsbourne Road and turn left onto Illawarra Road and travel north to the Bass Highway.
• Route 3 (Orange) – When Illawarra Road is closed to the east and west of the town entrance, vehicles can travel out via Wilmores Lane, turn right onto Bishopsbourne Road and continue along the road to Carrick (Meander Valley Road), and then onto to the Bass Highway.

Even if your home is not inundated, you may be isolated for several days. You should have supplies for up to three days and be prepared for power and telecommunications outages. Note if you are isolated, you may not be able to access medical or other help if needed.

Apa yang patut saya buat?

• Check the map to see whether your home or business is likely to be at risk during a flood.
• Check if you might not be able to safely get to your home, work, or school during a flood.
• Prepare a Home Emergency Plan. Consider if you need to evacuate before a flood. See Bersedia untuk Kecemasan – Panduan untuk individu dan isi rumah bersiap sedia menghadapi kecemasan. 
• Nilai rumah atau perniagaan anda dan bersiap sedia untuk meminimumkan kemungkinan kerosakan banjir.

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

BoM issues a Flood Watch when predicted weather might cause floods in one or two days. A Flood Watch may

• be for a specific area such as Longford.
• be for the South Esk River, or Macquarie River.
• be generalised such as for the Central North forecast area.

BoM issues a Severe Weather Warning for very heavy rain that may lead to flash floodingwhenever this weather is occurring or is expected in an area. The amount of time between the warning and the arrival of the heavy rain can vary from an hour to 24 hours or sometimes more.

BoM issues Flood Warnings with specific flood heightsfor the South Esk River at Longford gauging site with warnings of flood heights. Flood warnings can be issued for Minor (3.5m), Moderate (5.0m) dan Major (7.0m) flood levels.

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

If you live in a low-lying area you may be at risk of flooding. Even if your home is safe, you may need to detour around flooded areas. Never drive through or enter flood waters.

Knowing what to do can save your life and help protect your property. Preparing a Home Emergency Plan is one of the best ways to prepare.

Include weather and rainfall triggers for action in your Home Emergency Plan.

Ketahui risiko anda, bersiap sedia, kurangkan risiko di mana boleh, berhubung dengan orang lain, sentiasa berwaspada dan bertindak selamat.

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.

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.

Maklumat dalam panduan ini adalah terkini pada tarikh penerbitannya. Walaupun segala usaha telah dibuat untuk memastikan kesahihan dan ketepatan data yang dibentangkan, Perkhidmatan Kecemasan Negeri tidak bertanggungjawab ke atas kesilapan atau ketinggalan data.
