I roto i ngā mahi hangarau ā-pākihi, ā-tāone, me te taiao, me whai taputapu motuhake te ine i te rere o ngā wai kore-pēhanga—pērā i te wai para i roto i ngā whare rongoā, te wai ua i roto i ngā awaawa waikeri, te wai whakamakuku rānei i roto i ngā awaawa ahuwhenua. Kāore i rite ki ngā pūnaha paipa kati, e taea ai e ngā mita rere te whakamahi tika i te pēhanga, i te tere rānei, ko ngā awaawa tuwhera (e tautuhia ana ko ngā awaawa kua kī tonu i te wāhi e rere ai te wai e te kaha ā-papa) e hiahia ana ki ngā hangarau kua whakaritea kia rite ki ō rātou āhuatanga ahurei. Kua puta ake ngā mita rere awaawa tuwhera hei otinga, e whakakotahi ana i te tika, te urutau, me te pakari ki te aroturuki i te rere i roto i ēnei taiao wero.
Te Mahi a ngā Mita Rere o te Hongere Tuwhera: Te Tūranga o ngā Pā me ngā Āwhiowhio
Kei te ngako o te ine rere o te awa tuwhera te mātāpono o te hohonutanga nui—he wāhi e tutuki ai te tere me te hohonutanga o te wai ki tētahi hononga pumau, e taea ai te tatau i te tere rere mai i te hohonutanga anake. Ka whakawhirinaki ngā mita rere o te awa tuwhera ki ngā hanganga pēnei i ngā pā wai, i ngā awaawa rānei hei hanga i tēnei hohonutanga nui, kātahi ka whakamahia ngā pūoko hei ine i te taumata wai ka puta, ka hurihia hei tere rere mā roto i ngā tātai kua whakatūria.
He ārai te pā wai e whakatakotoria ana puta noa i te awaawa, e akiaki ana i te wai kia rere i runga i tētahi kōhao (hei tauira, he āhua-V, he tapawhā rite, he tapawhā rite rānei). Ko te teitei o te wai i runga ake i te pā wai (upoko) e pā tika ana ki te tere rere, e ai ki ngā paerewa hangarau (hei tauira, ISO 1438/1, ASTM D524 rānei). Hei tauira, he pai te pā wai V-kōhao mō ngā tono rere iti pērā i ngā awa iti, engari he pai ake te pā wai tapawhā rite mō ngā rere teitei ake i roto i ngā awaawa ā-tāone.
He paipa hanga motuhake te kōrere e whakawhāiti ana i te rere, e whakateretere ana i te tere, e hanga ana i te rerekētanga ine i te taumata wai i waenga i ngā wāhanga o te awaawa (kōkuhu) me te wāhanga o te korokoro. Ko ngā hoahoa noa ko ngā kōrere Parshall (e whakamahia whānuitia ana i roto i te wai para) me ngā kōrere Palmer-Bowlus (mō ngā paipa porowhita e rere ana me te kī tonu). He pai ake ngā kōrere i ngā pā wai i roto i ngā tono me ngā paru, nā te mea ka whakaitihia e tōna hoahoa ngāwari te aukati.
Hei ine i te taumata wai, ka whakamahia e ngā mita rere o ngā awa tuwhera hou ngā pūoko pēnei i ngā transducers ultrasonic (kore-pa, he pai mō te wai paru), ngā transducers pēhanga (kua rukuhia, he pai mō te wai ma), ngā pūoko radar rānei (ātete ki te pokanoa o te rangi). Ka tukuna e ēnei pūoko ngā raraunga ki tētahi tuku, e whakamahi ana i ngā whārite motuhake ki te pūaha/awa wai hei tatau i te tere rere i te wā tūturu.
Ngā Whakamahinga Matua: Ngā Wāhi e Whakamahia ai e Ngā Mita Rere o te Hongere Tuwhera ki te Excel
He mea nui ngā mita rere o te awa tuwhera puta noa i ngā rāngai e kaha ana te rere e pehia ana e te kaha ā-papa:
- Te Maimoatanga o ngā Wai Para o te Tāone: Ka aroturukihia e rātou te rere o ngā wai para (wai para mata) me ngā wai para (wai kua rongoatia), me te whakarite kia tutukihia ngā ture tukunga me te arotau i ngā tukanga maimoatanga. He mea tino noa ngā awa Parshall ki konei, nā te mea ka taea e rātou te whakahaere i te wai totoka me te kore e aukati pinepine.
- Te Whakahaere Wai Ua: Ka whakamahia e ngā tāone nui ēnei hei aroturuki i te rerenga wai i roto i ngā awa waikeri, hei ārai i te waipuke mā te whakatūpato i ngā kaiwhakahaere ki ngā pikinga ohorere o te rere. Ko ngā pūoko ultrasonic kore-pā te mea e pai ake ana ki konei, nā te mea he maha ngā wā ka haria e te wai ua ngā paru ka kino pea ngā taputapu kua rukuhia ki raro.
- Ahuwhenua: I roto i ngā pūnaha whakamakuku, ka inehia e ngā mita rere o ngā awaawa tuwhera te tohatoha wai ki ngā mara, hei āwhina i ngā kaimahi pāmu ki te whakapai ake i te whakamahinga me te whakatutuki i ngā ture mō te tika wai. He maha ngā wā ka whakamahia ngā pā wai ki ngā awaawa iti, engari he pai ngā awaawa mō ngā awaawa nui ake.
- Aroturuki Taiao: Ka aruhia e rātou te rere o ngā awa, ngā manga iti, me ngā repo hei ako i ngā rauemi wai, i te hauora o te rauropi, i te pānga rānei o ngā tukunga wai ā-umanga. Mā ngā tauira ultrasonic kawe ka taea te tāutanga rangitahi mō te rangahau mara.
Ngā Painga me ngā Here: Te Kōwhiri i te Hangarau Tika
He painga motuhake ngā mita rere o te awa tuwhera mō ngā pūnaha kore pēhanga:
- Ngāwari ki te Urutau: Ka mahi ēnei me ngā āhua me ngā rahi o ngā awaawa rerekē (tapawhā rite, porowhita, trapezoidal) mai i ngā paipa iti ki ngā awaawa nunui.
- Te Whai Hua o te Utu: Kāore he wāhanga neke o ngā pā wai me ngā awaawa, ā, ka whakaitihia ngā utu tiaki ki te whakaritea ki ngā mita miihini. Ka āraihia e ngā pūoko kore-pa (ultrasonic, radar) te pakaru mai i ngā wai whakakoi.
- Te Whakatutukitanga: E tutuki ana i ēnei paerewa o te ao mō te tika, ā, e pono ai mō ngā pūrongo ture (hei tauira, ngā whakaaetanga wai para a te EPA).
Heoi anō, he herenga anō kei a rātou hei whakaaroaro:
- Ngā Whakaritenga Tāutanga: Me tika te whakarite i ngā pā me ngā awaawa me ngā whakarerekētanga o ngā awaawa kia tika ai te hanganga o te hohonutanga nui. Ka taea e ngā hanganga kāore i te pai te tāuta te arahi ki ngā hapa ine.
- Te Pāwera ki ngā Para: Ka noho pūngāwerewere ngā pā wai i ngā rau, i ngā paru, i ngā para rānei, ka whakararuraru i te rere o te wai, ka whakapōturi hoki i ngā inenga. Me horoi auau i ngā taiao paru.
- Ngā Here o te Awhe Rere: Ka pai te mahi a ia hoahoa pā wai, ia hoahoa awa rānei i roto i tētahi awhe rere motuhake. Tērā pea kāore e tika ngā hanganga nunui i ngā rerenga iti, engari ka taea e ngā hanganga iti te waipuke.
Ngā Auahatanga i roto i te Ine Rere o te Hongere Tuwhera
Nā ngā whanaketanga hou kua pai ake te mahi i roto i ngā āhuatanga uaua:
- Ngā Pūoko Atamai: Kei roto i ngā pūoko ultrasonic me ngā pūoko radar hou ngā āhuatanga horoi-ā-unoa (hei tauira, te horoi hau) hei ārai i te poke i roto i ngā tono wai para. Ka honoa hoki ki ngā tūāpapa IoT mō te aroturuki mamao me te tātari raraunga.
- Ngā Mita Maha-Tauwhā: Ko ētahi tauira e whakakotahi ana i te ine rere me ngā pūoko kounga wai (hei tauira, te pH, te paru), e whakarato ana i ngā raraunga whānui mō ngā tukanga taiao, ngā tukanga maimoatanga rānei.
- Ngā Pūnaha Kawe: Mā ngā mita mama, pākahiko me te hononga ahokore ka taea te whakatū rangitahi ki ngā wāhi tūmatanui, he mea tino pai mō te aroturukitanga ohorere, mō ngā rangahau poto rānei.
Whakamutunga
He mea nui te mahi a ngā mita rere wai tuwhera ki te whakahaere i ngā pūnaha wai kore-pēhanga, e tuku ana i te ine pono i ngā wāhi kāore e pai ana ngā hangarau paipa kati. Mā te whakamahi i ngā pā wai, ngā awaawa, me ngā pūoko matatau, ka whakatauritehia e rātou te tika, te roa, me te whai huatanga utu puta noa i ngā tono mai i te maimoatanga wai para ki te rangahau taiao. I te pakeke haere o ngā hanganga me te korenga o te wai, ka tipu haere tonu tā rātou mahi ki te arotau i te whakamahinga rauemi me te whakarite kia tutuki ngā ture—ka waiho hei tūāpapa mō te whakahaere wai hou.
