Kei te pūtake o tētahi kaupapa hiko wai nui te tāmi—he hanganga hangarau nui i hangaia hei aukati i te rere o te awa. Ko te mahi matua o te tāmi i roto i te horopaki hiko wai e rua ngā mahi: te waihanga i tētahi puna wai mō te rokiroki wai me te whakaputa i te "pūngao wai" (te tawhiti poutū o te wai e taka ana). Ko te hanganga o ēnei ārai kei roto i ngā mahi tino uaua me te nui o ngā rauemi i roto i te hangarau ā-iwi, e hiahia ana kia whai huarahi tika ki te haumaru, te whenua, me te whakahaere taiao.
1. Te Kōwhiringa Pae me te Rangahau Hangarau Whenua
Ka tīmata te tukanga hanga i mua noa atu i te ringihanga o te mita pūtoru tuatahi o te raima. Ka whakahaerehia he rangahau whenua whānui kia taea ai e te papa te tautoko i te taumaha nui o te tāhuna me te pēhanga o te wai.
Te Rūwhenua: Me tātari e ngā kaihangarau te hītori o ngā mahi tektonika i te rohe kia hoahoa ai i tētahi hanganga e kaha ana ki te tū atu i ngā rūwhenua pea.
Āhuatanga uruhanga: Me whakamātau te turanga mō ngā " turuturu." Mena he tino pūngāwerewere te toka o raro, me nui te utu o te whakakī (te werohanga o te sima ki roto i ngā kapiti toka) hei ārai i te wai kei turuturu i raro i te tāhuna.
2. Te Hurihanga Awa: Te Hanga Whare i te Maroke
Hei hanga i tētahi tāhuna, me maroke te awa. Ka tutuki tēnei mā te tukanga e kīia nei ko te River Diversion.
Ngā tāmi wai: Ka hangaia ngā tāmi rangitahi, e mōhiotia ana ko ngā tāmi wai, ki runga ake me raro iho o te papa hangahanga hei aukati i te wai.
Ngā Ana Whakahuri: Kātahi ka akiakihia te awa mā roto i ngā ana nunui kua keria ki roto i ngā maunga e karapoti ana i te awa, mā roto rānei i tētahi awa rangitahi, kia taea ai te haere tonu o ngā mahi i te takotoranga o te awa kua kitea.
3. Ngā Momo Hanganga o ngā Pā Waiora
Ko te whiriwhiri i te hoahoa o te tāhuna ka whakawhirinaki ki te āhua o te awaawa me ngā rauemi e wātea ana:
Ngā Pā Ārai Kaha: He hanganga nunui ēnei i hangaia ki te raima, ki te kōhatu rānei. Ka whakawhirinaki katoa ki tō rātou ake taumaha hei ātete i te pēhanga whakapae o te wai.
Ngā Pā Āwhata: He hanganga piko ēnei e whakawhiti ana i te pēhanga o te wai ki ngā pakitara o te awaawa. He tino pai mō ngā awaawa whaiti, toka, ā, he iti ake te raima e hiahiatia ana i ngā pā āwhata.
Ngā Pā Tāwharau (Whakakī Whenua, Whakakī Toka rānei): He mea hanga mai i te oneone, i te toka rānei kua whakakikīhia, ā, he pūtake ā-roto kore e uru (he uku, he raima rānei te nuinga), ka whakamahia ēnei i ngā awaawa whānui ina kore pea te turanga e tautoko i tētahi hanganga raima taumaha.
4. Te Hanganga o te Tinana Matua me te Auahatanga Rauemi
Ko te hanganga tāhuna hou he maha ngā wā ka whakamahia te Konukura Whakakī-Roera (RCC). Ka whakatakotoria te RCC mā te whakamahi i ngā taputapu neke oneone, ā, ka whakakīia ki ngā roera wiri, he tere ake, he iti ake hoki te utu i te konukura "tūturu" tuku iho.
Te Whakahaere Wera: I roto i ngā tāhuna raima nui, ka puta he wera nui mai i te tauhohenga matū o te raima whakamaroke. Ki te kore e whakahaerea, ka pakaru te raima. Ka tāutahia e ngā miihini ngā paipa whakamatao o roto, ka whakamahia rānei he wai matao-hukapapa i te wā e whakaranua ana hei whakahaere i ngā pāmahana.
Te Ara Pupuhi: He wāhanga haumaru nui te ara pupuhi, ko te pūnaha "pukenga". Me hanga kia taea ai te whakahaere i ngā waipuke nui, kia kore ai te wai e rere ki runga i te wāhanga o te tāhuna kāore e pupuhi, ka arahi pea ki te pakaru o te hanganga.
5. Ngā Whakaaroaro Taiao me te Hapori
Kāore te hanganga o ngā tāhuna o ēnei rā e arotakengia ana i runga i te putanga hiko anake. Ko te pumautanga he whakaritenga matua ināianei:
Te Ara Ika: He maha ngā tāhuna kei roto i ēnei rā he "arawhata ika" he ararewa rānei hei tuku i ngā momo heke ki tua atu i te ārai.
Te Whakahaere Paraone: Ka mau te paru i ngā tāhuna, ka taea e ēnei te whakakī i te puna wai i te mutunga. Kei roto i ngā hoahoa hou he putanga iti hei horoi i te paru ki raro.
Te Whakanohoanga: Ko ngā kaupapa nui e uru ana ki te nekehanga o ngā hapori. Ko ngā aromatawai whānui mō ngā pānga pāpori he mea paerewa inaianei hei whakarite kia tiakina te oranga o ngā taupori o te rohe.
He mahi whakamiharo nā te auahatanga o te tangata te hanga i tētahi tāhuna mō tētahi teihana hiko wai. Me whai hononga tino pai o te hangarau ā-iwi, ā-waipēhi, me te taiao. I a te ao e rapu ana i ngā puna pūngao pumau, ka taea te whakahou hei whawhai i te huringa āhuarangi, ko te hanganga o ngā tāhuna tonu te tūāpapa o te rautaki pūngao o te ao—te whakataurite i te hiahia mō te hiko ma me te hiranga o te haumaru taiao me te hanganga.
