Te Ārahi a te Whakahoutanga Ine Wai AS4747 o Ahitereiria i ngā Mita Rere Radar ki te Taiwhenua

Koinei te taiao ā-tinana e hiahiatia ana e te paerewa ine AS4747:2025 o Ahitereiria te ine rere tonu, ātete-whakarerekē, ā-whakawhitiwhiti i ia putanga wai mata kua whakaritea i roto i te Murray-Darling Basin. Kāore te paerewa e tohu ana i tētahi hangarau pūoko motuhake. E tohu ana i ngā putanga: te tika i roto i te ±2.5% i raro i ngā āhuatanga o te mara, te hoahoa ā-tinana kāore e taea te whakarerekē, te ātete-whakarerekē rānei, me te tuku raraunga i te auau iti rawa o ia rā ki tētahi tūāpapa whakawhitiwhiti kōrero kāwanatanga-ā-rohe.

I te rohe raki o te awa — te Barwon-Darling, te Gwydir, te Namoi, te Macquarie — mā te whakakotahitanga o te rere ā-wā, te uta o ngā paru, me ngā wāhi tūmatanui ka kore e whakaarohia te nuinga o ngā hangarau. Ka whakangaromia ngā mita ultrasonic kua rukuhia e ngā paru. Ka whakangaromia ngā mita rere ā-ringa e ngā paru, ā, ka kore hoki e tutuki te whakaritenga ārai-whakarerekē — ka taea te whakatuwhera i tētahi kēti huri noa i a rātou. Me whai paipa tinana, he pā rānei mō ngā taputapu rerekē-pēhanga, he utu nui.

50,000 ki te 200,000 hei hanga me te kohi paru i ngā wā maroke.

He aha te Hiranga o te Radar, me te Kore-Whakapā Mai i Konei

Ko te tikanga rere o Barwon-Darling te take. Ka kohia e te pūoko ruku wai e noho ana i roto i te awa maroke mō ngā marama 18 te puehu, te tukutuku pungawerewere, me te waikura ki tōna mata whakawhiti. Ina tae mai te rere, he hē ngā pānui tuatahi a te pūoko mō ngā haora 24 ki te 48 tuatahi - ko te wā tonu tēnei e tino hira ai te ine tika, nā te mea koinei te wā e hurihia ana te wai ki ngā putunga i runga i te pāmu. Kia tau te pūoko, kua hipa kē pea te 40% o te kaupapa rere.

Kei runga i tētahi anga maitai te radar Honde e tū ana, e 4 ki te 10 mita i runga ake i te moenga o te awa. I roto i te wā maroke 18-marama, kāore e mahi i tetahi mea. Kāore e heke. Ina tae mai te rere, ko tana pānui tuatahi he rite te tika ki tōna mano. Ka hopukina e te wāhanga Doppler 24GHz te tere o te mata mai i te wā e puta ai te iahiko ka kitea. Ka hopukina e te radar taumata 60GHz, 80GHz rānei te taumata wai me te tika ±2mm. Ka whakauruhia e te tukatuka onboard te tere, te taumata, me te āhua whakawhiti-wāhanga o te awa kua tirotirohia hei tatau i te tere rere inamata i roto i ngā megaliters ia rā - te waeine e whakamahia ana e te kaute wai o Ahitereiria.

Ehara te tāuru āhuahanga whakawhiti-wāhanga i te whakatau tata kotahi. Ka ruritia te kōtaha o te awa i ia putanga i te wā tāutanga, ā, ka whakaurua ki te whirihoranga o te pūoko. Mena ka neke te awa — pērā i ngā awa oneone i ngā mania oneone pango o te Awaawa o Gwydir, inā koa i muri i ngā waipuke nui — ka whakahoutia te ruritia, ā, ka tukuatuhia te kōtaha hou mā te atanga RS485 Modbus. Kāore te pūoko e whakaaro he āhuahanga pumau. Ka whakaaetia he āhuahanga hou i ngā wā katoa ka huri te awa tūturu.

Te Arorau Ārai-Whakararuraru

Ko te aro nui o te paerewa AS4747 ki te ārai i ngā whakarerekētanga he whakautu tika ki ngā whakapae tahae wai o te tau 2017–2019 i te rohe raki o te awa, i reira i whakapaehia ai ngā kaiwhakawai wai mō te papu i ngā wā aukati me te whakahaere i ngā taputapu ine. Kāore e taea te ārai tinana i tētahi pūoko radar kore-pa e whakanohoia ana ki runga i tētahi awaawa i runga i tētahi arawhata maitai, te ruku ki roto i tētahi peere wai marino, te karo rānei mā te whakamahi i tētahi paipa huna. Ka kitea te arawhata mai i te rangi, ā, ka taea te tirotiro mā te whakaahua amiorangi e whakawhitihia ana ki ngā raraunga telemetry.

Kāore e taea te whakarerekē i te awa raraunga. Ka tāia te wā ki ia inenga 15-meneti, ka tāpirihia he tohu whenua, ā, ka tukuna tika atu ki te tūāpapa waea a te kāwanatanga ā-rohe — te tomokanga WaterInsights o NSW, te IWMS rānei o Kuīnirani — mā te MQTT Json. Kāore he mana whakakore ā-rohe. Kāore he atanga whakatika ā-ringa. Ka taea e te kaiwhakahaere tango raraunga te tiro i ngā raraunga. Kāore e taea e rātou te whakarerekē.

He mea nui tēnei nā te mea ko te Mahere o te Takotoranga o Murray-Darling, te whakaaetanga ā-kāwanatanga $13 piriona e whakahaere ana i te tiritiri wai i waenga i a New South Wales, Victoria, South Australia, me Queensland, e whakawhirinaki ana ki te kaute ka taea te arotake. Mena ka inehia te wai i tangohia mai i te tango wai i te Awa o Gwydir me te tika ±2.5% ka tukuna ki te tūāpapa kāwanatanga i roto i ngā haora 24, ka taea te tatau me te māia i te tohatoha rere taiao ki raro ki ngā Marsh o Macquarie. Mena he ±20% te inenga, ā, ka tae mai ngā raraunga ki runga pepa i muri i ngā marama e toru, ka pakaru te anga kaute katoa. Ka kati te radar kore-pa i taua āputa.

Hononga: Te Tikanga o te "Mamao" i te Taiwhenua o Ahitereiria

Ehara i te mea he whenua noa iho te Rohe o te Raki. He tūāpapa tawhiti, kāore e kitea e ngā whatunga pūoko o Ūropi. Kei te 120 kiromita te tawhiti o tētahi pāmu miro i te awa o Barwon-Darling e tata ana ki Brewarrina mai i te tāone tata rawa atu, neke atu i te 5,000 te taupori. Kei te taha o te Huarahi Matua o Kamilaroi te ratonga waea pūkoro. Kāore i te 40 kiromita te tawhiti atu i te huarahi matua i runga i te ara paru e anga atu ana ki tētahi papu awa.

Ko ngā waeine radar Honde e 45 i roto i te whakatinanatanga o te AS4747 e hono ana ki ngā papaaho telemetry mā roto i ngā waeine whakawhitiwhiti kōrero kua tohua mō ia pae. Ko ngā take i roto i te 15 kiromita o te tāone — Moree, Narrabri, Walgett, Bourke — e whakamahi ana i ngā waeine 4G. Ko ngā take i roto i ngā rohe mate pūtau e whakamahi ana i ngā waeine LoRaWAN e tuku raraunga ana ki ngā kuwaha i runga i ngā silo witi tata, i ngā pourewa Telstra rānei, me te whānuitanga 15 ki te 25 kiromita puta noa i te whenua papatahi. E toru ngā take i roto i ngā wāhanga tino tawhiti o te pūnaha Awa Paroo e whakamahi ana i te whakahoki amiorangi kua whakauruhia ki te kuwaha LoRaWAN.

I te taumata tango wai, kāore te kaiwhakawai e taunekeneke ki te kapua. Ka whakaatuhia e te Pūrakau Raraunga me te mata e whakanohoia ana ki roto i te rūma whakahaere o te whare papu te tere rere o nāianei i roto i ngā megaliters ia rā, te nui o te tango wai ia rā, me te ia o ngā rā 30. Ka tirohia e te kaiwhakawai te pūrakau hei wāhanga o tā rātou mahi o ia rā - pērā i tā rātou tirotiro i te pēhanga papu me ngā taumata wahie.

I te wā o te arotakenga ā-tau mō ngā whakaritenga, ka manatokohia ia pūoko e tētahi tohunga hangarau o WaterNSW ki tētahi mita ringaringa kawe, ā, ki te whakaaetia e ngā āhuatanga, ka tukuna iho he mita iahiko miihini mai i tētahi poti, piriti rānei. Ka tukuatuhia te rekoata whakatikatika ki te awa MQTT kotahi, ā, ka noho hei wāhanga o te ara arotake tuturu.

Te Arorau Whakaoho: Ina hipa te Tango i te Tohatoha

Kei te whakahaerehia te Pūnaha Whakawātea Wai o Murray-Darling i runga i tētahi pūnaha tohatoha wai. Kei ia mīhini whakamakuku he mana ā-tau, ā, i ia tau ka pānuitia e te kāwanatanga ā-rohe he ōrau tohatoha wai i runga i ngā taumata rokiroki. I te tau ua, ka eke pea ngā tohatoha wai ki te 100%. I te tau maroke, ka kore pea mō ngā kaiwhakamahi haumarutanga whānui.

Mā te ine rōrahi tonu o te pūoko radar 3-i roto-i te-1 ka taea te mahi i tētahi mahi kāore i taea e te ine ā-ringa: te whakatinana i te tohatoha wā-tūturu. Ka aroturukihia e te tūmau Kapua me te pūmanawa te tangohanga tāpiri mō ia tangohanga ki tōna rōrahi kua tohaina. Ina tae te tangohanga tāpiri ki te 95% o te tohatoha, ka tukuna e te pūnaha tuku Whakaoho he whakamōhiotanga aunoa ki te kaiwhakainu - he whakatūpato kei te tata te tangohanga ki te rohe ture. I te 100% o te tohatoha, ka taea e te tuku te whakaoho i te kati papu ā-tinana mena kua whirihorahia te pūnaha whakahaere o te tangohanga mō te tutuki aunoa.

I te tau wai 2025–2026, i kitea ai ngā rerenga wai i raro iho i te toharite puta noa i te rohe raki o te awa, ehara tēnei aroturuki tohatoha aunoa i te āhuatanga whai hua. Koinei te tikanga whakamana e whakakapi ana i te pūnaha o mua o ngā pānui mita whaiaro me ngā arotakenga tutukitanga matapōkere. Kāore ngā raraunga i te pūrongo whaiaro. Ka aunoatia, ka tāia te wā, ka tukuna tika atu ki te kaiwhakahaere ā-rohe.

Ngā Hua o te Marae: Northern Basin, NSW, Hanuere–Hōngongoi 2026

I whakatūria he whakatakotoranga tuatahi o ngā mita rere radar 3-i roto-i-te-1 kua whakamanahia e te CE, e 45, i waenganui i te marama o Hānuere me te marama o Poutū-te-rangi 2026 puta noa i ngā awaawa kua whakaritea i roto i ngā awaawa o Gwydir, Namoi, me Barwon-Darling.

Ngā hua o te mahi i muri i ngā marama e ono:

• Kāore he rahunga o te pūoko i te wā whakamakuku raumati 2025–2026, tae atu ki te werawera o Hānuere i eke ki te 47°C te pāmahana taiao i ngā awaawa o Brewarrina, me te rerenga o Poutū-te-rangi i whakawhiti i te Barwon-Darling mai i te maroke ki te 2,800 megaliters ia rā i roto i te iti iho i te 72 hāora. I ora te radar kore-pā i te whakawhiti me te kore he taumahatanga tinana.
• Nā te manatoko tika ki ngā inenga mita iahiko miihini i te 8 o ngā pae 45 i whakahokia mai he toharite rerekētanga o te ±3.1% — i roto i te whāinga ±2.5% i te 6 o ngā pae 8, me ngā pae e rua e toe ana me arotake anō te kōtaha o te awa i muri i te waipuke o Poutū-te-rangi i huri i te wāhanga whakawhiti o te awa.
• E toru ngā whakawetonga o te papu tohatoha-pau i te wā whakamakuku nā te pūnaha tuku whakaoho. I ia o ngā wāhi e toru, kāore te mīhini whakamakuku i aro turuki motuhake i te tangohanga katoa, ā, kua hipa ake pea i te tohatoha mā te 8–15% i raro i te pūnaha pūrongo-whaiaro o mua.
• I tutuki i te awa telemetry MQTT Json te 97.3% o te whakaotinga raraunga puta noa i ngā pae 45 katoa — neke atu i te 95% iti rawa i tohua i raro i te AS4747:2025. Ko te āputa raraunga 2.7% i whakawhāitihia i roto i te wā 6-rā i te marama o Pēpuere i te wā i pāngia ai te hononga 4G i te 7 pae e te motumotu o Telstra ā-rohe. Kāore i pāngia ngā pae LoRaWAN.
• I runga i te mahi a te whakatinanatanga, kua whakaaetia e te Tari Huringa Āhuarangi, Pūngao, Taiao me te Wai o NSW te whakawhānui ake ki te 120 atu wāhi tangohanga i te rohe raki o te rohe, ā, e matapaetia ana ka tīmata te hoko i te hauwhā tuatoru o te tau 2026.
