Kupu Whakataki
I roto i ngā mahi ahumahi me te taiao, he maha ngā wai nui kāore i te "ma"—whakaarohia te wai para kua whakakiia ki ngā paru, ngā paru keri kua ki tonu i te paru, ngā wai para ahumahi kei roto ngā totoka iri. Mō ēnei "wai paru," he maha ngā wā ka rahua ngā mita rere tuku iho: ka purua ngā mita miihini, ka raru ngā taputapu ultrasonic ki te pokanoa tohu, ā, ka tere te poke o ngā pūoko urutomo. Koinei te wāhi e tiaho ai ngā mita rere Doppler. Mā te whakamahi i te pānga Doppler—te wāhi e pupuhi ai ngā ngaru oro i ngā matūriki neke i roto i te wai hei tatau i te tere—ka hurihia e ēnei taputapu he wero (ngā totoka iri) hei painga. Kāore i rite ki ngā mita tuku iho e titiro ana ki te paru hei arai, ka whakawhirinaki ngā mita rere Doppler ki a ia, ka waiho hei whiringa matua mō te ine i ngā rere i roto i ētahi o ngā taiao wai tino kino, tino paru. Mai i te maimoatanga wai para ā-tāone ki ngā mahi keri, ka tukuna e rātou he raraunga pono, wā-tūturu e pupuri ana i ngā tukanga kia pai, kia tutuki, kia whai hua hoki.
He aha i tino pai ai ngā mita rere o te Doppler i roto i ngā wai paru?
Ko te mea ngaro o te angitu o ngā mita rere Doppler ki ngā wai paru kei roto i ō rātou ariā mahi ahurei me te hoahoa. Kāore i rite ki ngā mita rere ultrasonic e ine ana i te rere mā te tuku ngaru oro i roto i te wai (he ngāwari te whakararuraru e ngā mea totoka), ka tukuna e ngā tauira Doppler ngā ngaru oro auau-teitei (te nuinga o te wā 0.5–2 MHz) e aro ana ki ngā matūriki iri, ngā mirumiru, ngā para rānei i roto i te wai. Ina pā ēnei ngaru ki ngā matūriki e neke ana, ka neke tō rātou auau—ko tēnei nekehanga, e inehia ana e te pūoko o te mita, he rite tonu ki te tere o te wai. I te mea e hiahiatia ana te noho o ngā mea totoka mō ngā pānui tika, ehara ngā wai paru i te raruraru engari he whakaritenga, e whakakore ana i ngā take aukati me te paru e pāngia ana e ētahi atu mita.
Ko tētahi atu painga matua ko tōna hoahoa kāore e pokanoa, kāore hoki e pokanoa. Ko te nuinga o ngā mita rere Doppler he mea whakapiripiri: ka piri ki waho ki te paipa, kāore he pūoko e puta ana ki roto i te wai. Ko te tikanga kāore he pā ki ngā wai waikura, ngā wai whakakoi, ngā wai poke rānei—kāore he wāhanga hei pakaru, kāore he turuturu kei te tūpono, ā, kāore he take ki te kati i te pūnaha mō te tāutanga, te tiaki rānei. Hei tauira, i roto i tētahi paipa paru e mau ana i te kirikiri me te para rauropi, ka karohia e te mita Doppler whakapiripiri te tūponotanga o ngā aukati pūoko ka kore ai e whai hua te mita tāpine pokanoa. Ahakoa ngā tauira Doppler momo whakauru (e whakamahia ana mō ngā paipa nui ake) he pūoko pakari, he pania e ātete ana ki te pakaru me te kino matū, e whakarite ana i te roa o te ora i roto i ngā āhuatanga uaua.
Hei tāpiritanga, he whānui te hototahitanga o ngā mita rere Doppler ki ngā momo wai paru. Ka whakahaerehia e rātou ngā mea katoa mai i te wai para (me te 1–5% te ihirangi totoka) ki te keri paru (tae atu ki te 40% totoka), ngā wai matotoru pēnei i te wai poke hinu, tae atu ki ngā wai he mirumiru hau (hei tauira, te wai para hau). Ka noho rite tonu tō rātou tika (te tikanga ±2–5% o te pānui) puta noa i ēnei wai rerekē, ka pai ake i ētahi atu mita e hiahia ana ki ngā wai ma, ōrite kia pai ai te mahi.
Ngā Whakamahinga o te Ao Tūturu i roto i ngā Horopaki Wai Para
Nā te pono o ngā mita rere Doppler i roto i ngā wai paru kua tino hiahiatia ai i roto i ngā ahumahi maha, ā, kua ea hoki ngā wero ine roa.

Ko ngā whare wai para te kaiwhakamahi matua o ngā mita rere Doppler, e aroturuki ana i ngā rere o te wai para mata, te paru whakahohe, me te wai para kua tukatukahia—katoa kua whakakiia ki ngā totoka, ngā mea rauropi, me ngā para. I te tomokanga, ka ine ngā mita Doppler i te rere o te wai para mata hei whakapai ake i te kaha maimoatanga o te whare, kia kore ai e nui rawa te uta. I roto i ngā tāke hau, ka aroturukihia e rātou te rere o te wai para whakahohe (he ranunga matotoru, he nui ngā moroiti) hei pupuri i ngā taumata hāora tika, he mea nui mō te wawahi i ngā poke. Kāore i rite ki ngā mita miihini e purua ana e te paru, ka mahi pai ngā tauira Doppler, ka whakaiti i te wā kore mahi tiaki me te whakarite kia tutuki i ngā paerewa tukunga taiao.
Te Keri me te Tukatuka Kohuke
He nui ngā paru ka puta mai i ngā mahi keri - he ranunga wai me te konganuku pakaru, te onepu, ngā paru rānei (ngā rauemi para). He mea nui te ine tika i te rere o te paru hei whakapai ake i te whakaora kohuke me te whakahaere i ngā para. He tino pai ngā mita rere Doppler ki konei: ka whakahaerehia e rātou ngā paru tino koi (me ngā matūriki tae atu ki te maha mirimita te rahi) ka whakangaro i ētahi atu mita. Hei tauira, i roto i te keri parahi, ka whai ngā mita Doppler i te rere o ngā paru konganuku ki ngā tāke whakatārewatanga, te wāhi e wehea ai te parahi mai i te para e ngā matū. I roto i te whakahaere paru, ka aroturukihia e rātou te rere o ngā paru para ki ngā roto rokiroki, ka ārai i ngā waipuke me te kino ki te taiao. Ko tā rātou hoahoa kore-whakaeke ka karo hoki i te poke o te paru, he āwangawanga matua mō te parakore o ngā kohuke.
Te Hanga Ahumahi
He maha ngā tukanga hanga e whakaputa ana i ngā para paru e hiahia ana kia ine tika i te rere. Hei tauira, i roto i te tukatuka kai, ka aroturukihia e ngā mita Doppler te rere o te wai para kei roto ngā toenga kai, te hinu, me ngā hopi horoi—ngā wai ka ārai i ngā mita tuku iho. I roto i te hanga matū, ka inehia e rātou te rere o ngā wai waikura e konatunatua ana ki ngā hua totoka (hei tauira, ngā pire kirihou i roto i te hanga polymer), kia whakarite ai i te whakakorenga haumaru me te tutuki i ngā ture para. I roto i ngā mira penupenu me te pepa, ka aroturukihia e rātou te rere o te wai pango (he hua matotoru, he nui ngā matū o te penupenu rakau), ka āwhina i ngā mira ki te whakaora i te kaha mai i te wai, me te karo i te kino o ngā taputapu.
Te Hanganga me te Hangarau Ā-Iwi
He maha ngā wā ka pāngia ngā papa hanga e te wai paru mai i te keri, te horoi raima, te rerenga wai ua rānei (kua ki tonu i te paru). Ka whakamahia ngā mita rere Doppler hei ine i te rere o tēnei wai ki ngā pūnaha maimoatanga (hei tauira, ngā tāke paru) i mua i te tukunga, kia tutuki ai ngā ture taiao ā-rohe e aukati ana i te wai kua ki tonu i te paru kia uru ki ngā ara wai taiao. Nā te ngāwari ki te kawe - he maha ngā tauira he pākahiko, he ngāwari hoki te tāuta mō te wā poto - he mea pai mō ngā papa hanga, he wā poto noa iho ngā rere, ā, he maha ngā wā ka rerekē ngā wāhi.
