Ezisetshenzisweni zezimboni, zikamasipala, kanye nezemvelo—lapho uketshezi lugeleza khona ngeziteshi ezingavinjelwe (njengemifula, imisele, imisele yamanzi angcolile, noma imisele yokunisela)—ukulinganisa ukugeleza okunembile kubalulekile ekuphathweni kwezinsizakusebenza, ukuthobela imithetho, kanye nokusebenza kahle. Ngokungafani namamitha avaliwe (isib. amamodeli e-ultrasonic noma kagesi) athembele ezinhlelweni zoketshezi ezivaliwe, amamitha okugeleza eziteshini avulekile aklanyelwe ukukala ukugeleza eziteshini ezivulekile, eziqhutshwa amandla adonsela phansi, ukubhekana nezinselele ezihlukile zokugeleza okungavinjelwe—njengamazinga amanzi aguquguqukayo, ukwakheka kwenhlabathi, kanye nokushintshashintsha kwemvelo. Kusukela ekuqapheni ukukhishwa kwamanzi angcolile ezitshalweni zokwelashwa kuya ekwenzeni ngcono ukunisela emasimini ezolimo, la mamitha abe ngamathuluzi abalulekile ezimbonini ezithembele kudatha ethembekile ukuphatha izinsiza zamanzi. Ngokuhlanganisa ubuchwepheshe obuguquguqukayo nomklamo oqinile, amamitha okugeleza eziteshini avulekile awaxazululi nje kuphela ubunzima bokulinganisa ukugeleza okungavinjelwe kodwa futhi aqhuba ukusimama, ukonga izindleko, kanye nokuthobela imithetho—okuqinisa indima yawo ekuphathweni koketshezi lwesimanje.
Ukusebenza kahle kwamamitha okugeleza kwesiteshi esivulekile kuvela ezimisweni zawo zokusebenza ezenzelwe wena, ezichaza uhlobo oluguquguqukayo lokugeleza okuvulekile. Ngokungafani nezinhlelo zamapayipi avaliwe (lapho izinga lokugeleza lixhunyaniswe nokucindezela kanye nobubanzi bepayipi), ukugeleza kwesiteshi esivulekile kunqunywa yizici ezimbili ezibalulekile: indawo yesigaba sesiteshi kanye nejubane loketshezi. Ukuze ulinganise lokhu, amamitha esiteshi esivulekile ngokuvamile asebenzisa obunye bobuchwepheshe obubili obuyinhloko: ama-weirs noma ama-flume, ahlanganiswe nenzwa yezinga (isb., i-ultrasonic, i-radar, noma esekelwe kungcindezi). Ama-weirs angama-notches (isb., anomumo ongu-V, angunxande) afakwe esiteshini; njengoba amanzi egeleza phezu kwe-weir, ukuphakama kwamanzi ngaphezu kwe-notch (eyaziwa ngokuthi “ikhanda”) kuhlobene nezinga lokugeleza, elibalwa yinzwa yezinga kusetshenziswa amafomula alinganiswe ngaphambilini. Ama-flume, ngokuphambene, ayizingxenye ezincishisiwe zesiteshi ezisheshisa ukugeleza; inzwa yezinga ilinganisa ukuphakama kwamanzi endaweni ethile ku-flume, futhi izinga lokugeleza litholakala ebuhlotsheni phakathi kokuphakama nejubane. Lo mklamo ubhekana nenselele enkulu yokugeleza okuvulekile—ukuguquguquka: kungakhathaliseki ukuthi umsele uthwala amanzi amdaka anomthamo omncane noma amanzi emvula anomthamo omkhulu, imisele kanye nama-flume kudala iphethini yokugeleza ehambisanayo nelinganiswayo, okuqinisekisa ukunemba ngisho noma amazinga amanzi eshintshashintsha. Esikhungweni sokuhlanza amanzi amdaka sikamasipala, lokhu kusho ukulandelela ngokwethembeka ukukhishwa kokungcola ukuze kuhlangatshezwane nemithethonqubo yemvelo; kumlimi, kuqinisekisa ukunisela okunembile ukuze kugwenywe ukunisela izitshalo ngokweqile.
Ngaphandle kokunemba, amamitha okugeleza kwesiteshi esivulekile anikeza ukuqina kokusebenza ezindaweni ezinzima noma ezingalindelekile. Ngokungafani namamitha amapayipi avaliwe athambile angonakaliswa yi-sediment noma imfucumfucu, amamodeli esiteshi esivulekile akhelwe ukusetshenziswa okuqinile: ama-weirs nama-flume avame ukwenziwa ngezinto ezingagqwali (isb., insimbi engagqwali, i-fiberglass, noma ukhonkolo) ukuze amelane nokuchayeka kumakhemikhali, imisebe ye-UV, noma i-sediment erhabaxa (isb., isihlabathi emanzini ageleza ezolimo). Izinzwa zamazinga nazo zenzelwe ukuqina: izinzwa ze-ultrasonic, isibonelo, zifakwa ngaphezu kwamanzi (akukho ukuthintana okuqondile) ukuze kugwenywe ukungcoliswa yi-algae noma i-sludge, kuyilapho izinzwa ze-radar zisebenza ezimweni ezinothuli, ezinemvula, noma ezineqhwa—okuqinisekisa ukusebenza konyaka wonke. Ukugcinwa kuhlelekile ngokulinganayo: ngokungafani namamitha omshini adinga ukushintshwa kwezingxenye njalo, izinhlelo zesiteshi esivulekile zidinga ukuhlolwa ngezikhathi ezithile kuphela (isb., ukuhlanza izimbobo zemfucumfucu, ukulinganisa izinzwa zamazinga minyaka yonke). Komsebenzi wokumba, ovame ukubhekana namanzi agcwele i-sediment, lokhu kusho isikhathi esincane sokungasebenzi; esifundeni sokunisela esikude, kuqeda isidingo sokuvakasha njalo endaweni ukuze kusetshenzwe imishini ebuthakathaka.
Amamitha okugeleza eziteshini ezivulekile nawo anikeza ukuguquguquka kanye nokwelulwa, okwenza afanelekele izinhlelo zokusebenza ezahlukahlukene kuzo zonke izimboni. Angenziwa ngokwezifiso ukuze avumelane nanoma yiluphi usayizi wesiteshi—kusukela emiseleni emincane yezolimo (amasentimitha ambalwa ububanzi) kuya emiseleni emikhulu yezimboni (amamitha angaphezu kwangu-10 ububanzi)—futhi alungiswe ngezinhlobo ezahlukene zoketshezi, kufaka phakathi amanzi ahlanzekile, amanzi angcolile, amanzi esiphepho, ngisho namanzi amdaka. Lokhu kuguquguquka kubalulekile ezimbonini ezinezidingo ezahlukahlukene: izinhlangano zemvelo, isibonelo, zisebenzisa amamitha eziteshi ezivulekile ukuqapha ukugeleza komfula ukuze kubikezelwe izikhukhula; izitshalo zamandla zithembele kuzo ukukala ukungenisa kwamanzi apholile avela emachibini; kanti izindawo zokuhlanza uwoyela ziwasebenzisa ukulandelela ukukhishwa kwamanzi angcolile ukuze kuvinjelwe ukungcola. Ngaphezu kwalokho, amamitha eziteshi ezivulekile zesimanje ahlanganiswa nezinhlelo ezihlakaniphile: izinzwa zamazinga zingadlulisela idatha yesikhathi sangempela kumapulatifomu e-IoT ngokuxhumeka okungenantambo (i-LoRaWAN, yeselula) noma ngezintambo, okuvumela ukuqapha okukude kanye nezaziso ezenzakalelayo. Ku-utility wamanzi ephatha iziteshi eziningi zokunisela, lokhu kusho ukufaka idatha phakathi ukuze kuthuthukiswe ukusatshalaliswa kwamanzi; efektri, ivumela izaziso ezisheshayo uma amazinga okugeleza edlula imikhawulo yomthetho—ukugwema izinhlawulo kanye nokulimala kwemvelo.
Njengoba ukushoda kwamanzi emhlabeni jikelele kanye nemithethonqubo yezemvelo iba lukhuni kakhulu, amamitha okugeleza kweziteshi ezivulekile avele njengesixazululo esizinzile, esiqinisekisa ikusasa sokulinganisa ukugeleza okungavinjelwe. Ikhono lawo lokusingatha izimo eziguquguqukayo, ukumelana nezimo ezinzima, nokuhlanganiswa nobuchwepheshe obuhlakaniphile lenza kube yinto ebalulekile ezinhlanganweni ezifuna ukuphatha izinsiza zamanzi ngempumelelo nangokuhambisana. Kungakhathaliseki ukuthi asetshenziselwa ukuvikela imvelo (ngokuqapha impilo yomfula), ukunciphisa imfucuza (ngokwenza ngcono ukuchelela), noma ukuqinisekisa ukuthobela imithetho (ngokulandelela ukukhishwa kwezimboni), la mamitha afakazela ukuthi ukulinganisa ukugeleza kweziteshi ezivulekile akudingeki kube yinkimbinkimbi—noma kungathembeki. Ezweni lapho ukuphathwa kwamanzi okunomthwalo wemfanelo kubalulekile khona, amamitha okugeleza kweziteshi ezivulekile angaphezulu nje kwamathuluzi—abalingani ekuqhubekiseni ukusimama, ukusebenza kahle, kanye nokuphepha kwezinsiza zesikhathi eside. Kunoma yimuphi umkhakha osebenza nezinhlelo zamanzi ezingavinjelwe, ukutshala imali kumitha yokugeleza kweziteshi ezivulekile akuyona nje inketho—kuwukuzibophezela ekuphathweni kwamanzi okusebenzayo, okuhambisanayo, nokuqhubekayo.
