I roto i ngā mahi ahumahi, ā-tāone, me te taiao—i te wā e rere ana ngā wai mā roto i ngā awaawa kore here (pērā i ngā awaawa, ngā awaawa wai, ngā awaawa whakamakuku rānei)—he mea nui te ine tika i te rere mō te whakahaere rauemi, te tutuki i ngā ture, me te whai huatanga o te mahi. Kāore i rite ki ngā mita paipa kati (hei tauira, ngā tauira ultrasonic, electromagnetic rānei) e whakawhirinaki ana ki ngā pūnaha wai kua kati, kua hangaia ngā mita rere awaawa tuwhera hei ine i te rere i roto i ngā awaawa tuwhera, e peia ana e te kaha ā-papa, e aro ana ki ngā wero ahurei o te rere kore here—pērā i ngā taumata wai rerekē, te hanga paru, me ngā huringa taiao. Mai i te aroturuki i te tukunga wai para i ngā tipu maimoatanga ki te arotau i te whakamakuku i ngā mara ahuwhenua, kua noho ēnei mita hei taputapu tino nui mō ngā ahumahi e whakawhirinaki ana ki ngā raraunga pono hei whakahaere i ngā rauemi wai. Mā te whakakotahi i te hangarau urutau me te hoahoa pakari, kāore ngā mita rere awaawa tuwhera e whakaoti noa i ngā uauatanga o te ine rere kore here engari e akiaki ana hoki i te pumau, te penapena utu, me te tutuki—e whakakaha ana i tā rātou mahi i roto i te whakahaere wai hou.
Ko te whai huatanga o ngā mita rere o te awa tuwhera e ahu mai ana i ō rātou mātāpono mahi kua whakaritea, e whakamārama ana i te āhua hihiri o te rere tuwhera. Kāore i rite ki ngā pūnaha paipa kati (e hono ana te tere rere ki te pēhanga me te diameter o te paipa), ka whakatauhia te rere o te awa tuwhera e ngā āhuatanga matua e rua: te horahanga whakawhiti o te awa me te tere o te wai. Hei ine i tēnei, ko ngā mita awa tuwhera e whakamahi ana i tētahi o ngā hangarau matua e rua: ngā pā wai, ngā awa rānei, e honoa ana ki tētahi pūoko taumata (hei tauira, te ultrasonic, te radar, te pēhanga rānei). Ko ngā pā wai he kōhao (hei tauira, he āhua-V, he tapawhā rite) kua tāutahia ki te awa; i te mea e rere ana te wai i runga i te pā wai, ko te teitei o te wai i runga ake i te kōhao (e mōhiotia ana ko te "upoko") e pā ana ki te tere rere, ka tatauhia e te pūoko taumata mā te whakamahi i ngā tātai kua whakaritea i mua. Ko ngā awa wai, he rerekē, he wāhanga kuiti o te awa e whakateretere ana i te rere; ka ine te pūoko taumata i te teitei o te wai i tētahi wāhi motuhake i roto i te awa wai, ā, ka ahu mai te tere rere i te whanaungatanga i waenga i te teitei me te tere. Ka arohia e tēnei hoahoa te wero nui rawa atu o te rere tuwhera—te rerekētanga: ahakoa he iti te wai para e rere ana i roto i te awaawa, he nui rānei te wai ua, ka hangaia e ngā pā me ngā awaawa he tauira rere ōrite, he ine, kia tika ai ahakoa te piki me te heke o ngā taumata wai. Mō tētahi tipu maimoatanga wai para ā-tāone, ko te tikanga o tēnei he aroturuki pono i te tukunga para kia tutuki ai ngā ture taiao; mō tētahi kaiahuwhenua, ka whakarite kia tika te horopeta whakamakuku kia kore ai e nui rawa te whakamakuku i ngā hua.
Haunga te tika, ka tukuna e ngā mita rere awa tuwhera te manawanui mahi i roto i ngā taiao uaua, kāore hoki i te matapaetia. Kāore i rite ki ngā mita paipa kati ngawari ka pakaru pea i te paru, i te para rānei, ka hangaia ngā tauira awa tuwhera mō te whakamahinga pakari: he maha ngā wā ka hangaia ngā pā me ngā awaawa ki ngā rauemi ātete-waikura (hei tauira, te maitai kore waikura, te muka karāhe, te raima rānei) hei ātete ki te pānga ki ngā matū, ki te hihi UV, ki ngā para rānei (hei tauira, te onepu i roto i te rerenga ahuwhenua). He mea hanga hoki ngā pūoko taumata mō te roa: hei tauira, ka whakanohoia ngā pūoko ultrasonic ki runga ake i te wai (kāore he pa tika) hei karo i te poke o te rimurimu, te paru rānei, i te mea ka mahi ngā pūoko radar i roto i ngā āhuatanga puehu, ua, hukapapa rānei—e whakarite ana i te mahi puta noa i te tau. He rite tonu te ngāwari o te tiaki: kāore i rite ki ngā mita miihini e hiahia ana ki te whakakapinga wāhanga maha, ko ngā pūnaha awa tuwhera me tirotiro noa i ia wā (hei tauira, te horoi i ngā kohao o te pā mai i ngā paru, te whakataurite i ngā pūoko taumata ia tau). Mō te mahi keri, e mahi ana ki te wai kapi i te paru, ko te tikanga he iti noa te wā whakatā; mō te rohe whakamakuku tawhiti, ka whakakorehia te hiahia mō ngā haerenga maha ki te wāhi hei mahi i ngā taputapu pakarukaru.
Ka taea hoki e ngā mita rere o te awa tuwhera te whakamahi i ngā āhuatanga maha me te whānui, ā, he pai mō ngā tono kanorau puta noa i ngā ahumahi. Ka taea te whakarite kia uru ki ngā rahi o te awa - mai i ngā awaawa ahuwhenua iti (he torutoru inihi te whānui) ki ngā awaawa ahumahi nui (10+ putu te whānui) - ā, ka taea te urutau ki ngā momo wai rerekē, tae atu ki te wai ma, te wai para, te wai ua, tae atu ki ngā paru. He mea nui tēnei ngāwari mō ngā ahumahi he rerekē ngā hiahia: hei tauira, ka whakamahia e ngā tari taiao ngā mita awa tuwhera hei aroturuki i te rere o te awa mō te matapae waipuke; ka whakawhirinaki ngā tipu hiko ki a rātou hei ine i te wai whakamatao e kohia ana mai i ngā roto; ā, ka whakamahia e ngā whare whakapai hinu hei aroturuki i te tukunga wai para hei ārai i te parahanga. Hei tāpiri, ka honoa ngā mita awa tuwhera hou ki ngā pūnaha atamai: ka taea e ngā pūoko taumata te tuku raraunga wā-tūturu ki ngā tūāpapa IoT mā te ahokore (LoRaWAN, waea pūkoro) me ngā hononga waea rānei, ka taea ai te aroturuki mamao me ngā whakatūpato aunoa. Mō tētahi ratonga wai e whakahaere ana i ngā awaawa whakamakuku maha, ko te tikanga o tēnei ko te whakakotahi i ngā raraunga hei arotau i te tohatoha wai; mō tētahi wheketere, ka taea ai ngā whakamōhiotanga inamata mēnā ka nui ake ngā reiti rere i ngā rohe ture - ka karo i ngā whiu me ngā kino ki te taiao.
I te mea ka kaha haere te korenga o te wai o te ao me ngā ture taiao, kua puta ake ngā mita rere awa tuwhera hei otinga pumau, ā-mua mō te ine i te rere kore here. Nā tō rātou kaha ki te whakahaere i ngā āhuatanga rerekē, te ātete i ngā taiao uaua, me te whakauru atu ki te hangarau atamai, he mea nui ēnei mō ngā whakahaere e rapu ana ki te whakahaere i ngā rauemi wai me te whai hua me te tutuki i ngā whakaritenga. Ahakoa e whakamahia ana hei tiaki i ngā rauropi (mā te aroturuki i te hauora o te awa), hei whakaiti i te para (mā te arotau i te whakamakuku), hei whakarite rānei kia tutuki i ngā ture (mā te aroturuki i te tukunga o ngā mahi ahumahi), ka whakaatu ēnei mita kāore e hiahiatia kia uaua te ine i te rere awa tuwhera—me te kore pono rānei. I roto i te ao e tino nui ana te whakahaere wai kawenga, ehara i te mea he taputapu noa iho ngā mita rere awa tuwhera—he hoa mahi rātou ki te whakatairanga i te pumau, te hiranga whakahaere, me te haumarutanga rauemi mo te wā roa. Mō tetahi ahumahi e mahi ana me ngā pūnaha wai kore here, ehara i te mea he kōwhiringa noa te haumi ki tētahi mita rere awa tuwhera—he whakapau kaha ki te whakahaere wai whai hua, tutuki i ngā whakaritenga, me te pumau.
