Ko ngā awa, hei puna ora mō ngā pūnaha rauropi whenua me ngā hapori tangata, me aroturuki tonu, me te tika hoki hei whakatika i ngā wero pēnei i te waipuke, te korenga o te wai, me te parahanga. He maha ngā wā ka kore e taea te aroturuki i ngā pūnaha aroturuki rere pumau tuku iho i ngā taiao awa tawhiti, hihiri rānei, nā te nui o ngā utu tāutanga me te iti o te nekenekehanga. I roto i tēnei horopaki, kua puta ake ngā mita rere awa tuwhera kawe hei taputapu whakarerekē i te kēmu, e tuku ana i te ngāwari, te māramatanga wā-tūturu, me te whai huatanga utu mō te aroturuki awa puta noa i ngā āhuatanga rerekē. Nā tō rātou kaha ki te urutau ki ngā āhuatanga rerekē o te awa—mai i ngā awa maunga whaiti ki ngā awa whānui o te whenua pāpaku—he mea nui ēnei mō ngā tohunga wai, ngā kaiwhakahaere taiao, me ngā rōpū rauemi wai puta noa i te ao.
Kei te pūtake o ngā mita rere o te awa tuwhera kawe ko te hangarau i hangaia mō te ine i te wāhi, kāore e pokanoa. E rua ngā hangarau matua e whakakaha ana i te nuinga o ngā taputapu: te rongonga ultrasonic me te whakaawe hikohiko. Ka mahi ngā tauira ultrasonic mā te tuku ngaru oro puta noa i te awaawa; ko te wā e pau ana mō ngā ngaru ki te peke atu i te mata o te wai, i te awaawa rānei, ka whakamahia hei tatau i te hohonu o te wai, ko te tere ka ahu mai i te nekehanga Doppler o ngā ngaru e whakaatahia ana e ngā matūriki wai e neke ana. He pai tēnei tikanga mō ngā awa pāpaku ki te hohonu āhua, nā te mea ka karohia te pa tika ki te wai, ā, ka whakaitihia te whakararuraru i ngā mea ora o te wai. Ko ngā mita rere hikohiko, he rerekē, ka whakawhirinaki ki te Ture a Faraday mō te whakaawe hikohiko: ina rere te wai (he reo kawe) i roto i te papa aukume i hangaia e te taputapu, ka puta he ngaohiko iti. Ko te rahi o tēnei ngaohiko he rite ki te tere o te wai, e taea ai te ine tika ahakoa i roto i ngā awa paru, kua ki tonu i te paru - he mea noa i roto i ngā rohe he rerenga ahuwhenua, he horo rānei. Ka whakauruhia ngā hangarau e rua ki roto i ngā waeine pākahiko kiato, e taea ai e ngā tīma mara te whakarite me te whakahaere i roto i ngā meneti, me te kore e hiahiatia he taputapu taumaha, he hanganga pumau rānei.
He rerekē, he whai pānga hoki ngā painga o ngā mita rere kawe i roto i ngā tono awa, mai i te nekehanga me te ngāwari kāore e taea te whakataurite. Kāore i rite ki ngā pūnaha pumau, e herea ana ki ngā wāhi kua tāutahia i mua, ka taea te kawe i ngā taputapu kawe ki tētahi wāhanga awa - ahakoa he awa tawhiti i roto i te ngahere, he awa taone nui rānei e tere ana te waipuke. Hei tauira, i te wā o te rangahau i muri i te tupuhi, ka taea e ngā tohunga wai te whakatakoto tere i ngā mita kawe maha i te roanga o te awa hei mahere i ngā rerekētanga rere, te tautuhi i ngā wāhi e kohia ana te paru, e horo ana rānei ngā awa e ngaro pea i ngā pūoko pumau. He mea nui hoki tēnei ngāwari mō te aroturuki i ngā awa rangitahi (e maroke ana i ia wā), ki te wāhi e maumauria ai, e kore hoki e whai hua ngā tāutanga pumau.
Ko te kohikohi raraunga wā-tūturu tētahi atu painga matua, e aro ana ki te tere o ngā mahi whakahaere awa maha. Ka whakaatuhia tonutia e ngā mita rere wai kawe te tere rere, te hohonutanga o te wai, me te tere i runga i ngā mata kua hangaia, mā roto rānei i ngā taupānga pūkoro e hono ana ki te Nihokikorangi. He mea nui tēnei tere mō te urupare waipuke: ina raru te hapori i te ua nui, ka taea e ngā tīma mara te whakamahi i ngā mita kawe hei ine i ngā taumata awa e piki haere ana i te wā-tūturu, ka whakaratohia ki ngā mana whakahaere ā-rohe ngā raraunga hei tuku i ngā whakatūpato whakawātea i te wā tika. Waihoki, i ngā wā tauraki, ka āwhina ngā raraunga rere wā-tūturu i ngā kaiwhakahaere wai ki te whakarerekē i ngā rohe tango wai mō te ahuwhenua, mō te whakamahinga ā-tāone rānei, kia mau tonu ai te tohatoha me te kore e kino ki ngā rauropi awa.
Mā te whai huatanga o te utu ka whakaū ake i te uara o ngā mita rere kawe. Ka taea e ngā teihana aroturuki awa pumau te utu tekau mano tāra hei tāuta me te tiaki, tae atu ki ngā whakapaunga mō ngā turanga raima, ngā puna hiko, me ngā tirotiro auau i te papaanga. He rerekē, ko ngā tauira kawe, he iti ake ngā utu o mua (he iti noa iho i ngā pūnaha pumau) me te iti o ngā hiahia tiaki—ko te nuinga he whakakapi pākahiko me te whakatikatika pūoko i ētahi wā. Mō ngā whakahaere taiao iti, mō ngā kāwanatanga ā-rohe rānei he iti ā rātou tahua, nā tēnei utu ka taea te aroturuki awa tonu mō te wā tuatahi.
I roto i te mahi, e tautoko ana ngā mita rere wai tuwhera kawe i ngā mahi nui e toru e pā ana ki te awa: te rangahau wai, te whakahaere rauemi wai, me te aroturuki taiao. I roto i te rangahau wai, ka whakamahia e ngā kaipūtaiao ēnei hei ako i ngā tauira rere o te wā—hei tauira, te whai i te pānga o te hukarere i roto i ngā awa maunga ki te rere o te wai i raro i te awa. Ka āwhina ēnei raraunga ki te whakapai ake i ngā tauira matapae waipuke me te whakapai ake i te māramatanga ki ngā pānga o te huringa āhuarangi ki ngā pūnaha awa. I roto i te whakahaere rauemi wai, ka whakarite ngā mita kawe i te tohatoha wai tika: i ngā rohe e whakawhirinaki ana ngā kaimahi pāmu maha ki te awa kotahi mō te whakamakuku, ka manatoko ngā mita kāore he kaiwhakamahi e neke atu i ngā rohe wai kua tohaina, ka ārai i ngā pakanga me te whakaiti i te para. Mō te aroturuki taiao, he mahi nui tā rātou i roto i te urupare parahanga: ki te puta he turuturu matū, ka ine ngā mita rere i te tere rere o te awa, ka taea e ngā mana whakahaere te tatau i te tapeke o te wai poke me te hoahoa rautaki horoi kua whakaritea. Ka aroturukihia hoki e rātou te hauora taiao mā te whai i ngā tere rere e tino nui ana mō ngā momo wai—hei tauira, te whakarite i te iti rawa o ngā rere i roto i ngā awa hei tiaki i ngā whenua whakaputa uri ika.
Ahakoa ō rātou painga, ka raru ngā mita rere kawe i roto i ngā āhuatanga awa kino. Ka taea e ngā rere pōrearea (he mea noa i roto i ngā awa maunga tere) te whakararuraru i ngā pānui a ngā pūoko, ko ngā kukū paru nui ka ārai i ngā pūoko hikohiko i roto i te wā. Hei whakatika i ēnei take, kua whakawhanakehia e ngā kaihanga ngā otinga motuhake: kei roto i ngā mita ultrasonic ngā rauropi whakatikatika pōrearea hei tātari i ngā raraunga pōturi, ā, kei ngā pūoko hikohiko he paninga ātete-kakahu hei peia i te paru. Hei tāpiri, he maha ngā taputapu kua whakatauria mō te mahi ātete-wai me te puehu (he maha ngā wā IP67, teitei ake rānei), e whakarite ana i te roa o te wā i roto i te ua nui, i ngā taiao paru rānei.
Hei whakamutunga, kua hurihia e ngā mita rere awa tuwhera kawe te aroturukitanga awa mā te whakakotahi i te nekenekehanga, te tere, me te utu whaitake. Ka whakakīia e rātou ngā āputa i mahue i ngā pūnaha pumau, ka taea ai te kohikohi raraunga i roto i ngā taiao awa tawhiti, hihiri rānei, ā, ka whakamana i ngā kaipupuri whakaaro ki te whakatau whai whakaaro mō te mōrearea waipuke, te tohatoha wai, me te tiaki taiao. I te whanaketanga o te hangarau—me ngā tauira o muri mai e whakauru ana i te hononga IoT mō te tiritiri raraunga wā-tūturu puta noa i ngā tīma—ka tipu haere tonu tā rātou mahi i roto i te whakahaere awa pumau. Mō te hunga katoa e whai kawenga ana ki te tiaki i ngā awa, ehara ēnei taputapu kawe i te mea papai engari he mea nui, e whakarite ana kia aroturukitia, kia tiakina, kia whakahaerehia hoki ngā pūnaha wai māori nui o tō tātou ao mō ngā whakatipuranga e haere ake nei.
