Ukwehliswa kwamanzi olwandle kubangela ukulimala kwemvelo futhi kungaba nomthelela omubi ezitshalweni nezilwane zasolwandle.
“Ukulimala ngokomzimba noma ukufa ngenxa yokushayisana, ukukhiqizwa komsindo, nokwanda kwezinxushunxushu izindlela eziyinhloko ukugwedla okungathinta ngazo ngokuqondile izilwane ezincelisayo zasolwandle,” kusho isihloko se-ICES Journal of Marine Science.
“Imiphumela engaqondile yokugwetshwa kwezilwane ezincelisayo zasolwandle ivela ekushintsheni kwendawo ezikuyo noma inyamazane yazo. Izici ezibonakalayo, njenge-toography, ukujula, amagagasi, ukugeleza kwamanzi, usayizi wezinhlayiya ze-sediment kanye nokugxila kwenhlabathi okumisiwe, kuyashintshwa ngokudonswa, kodwa izinguquko zenzeka ngokwemvelo ngenxa yezenzakalo eziphazamisayo njengamagagasi, amagagasi neziphepho.
Ukwehliswa kungaba nomthelela omubi otshanini basolwandle, okuholela ezinguqukweni zesikhathi eside ogwini futhi okungase kufaka imiphakathi yasogwini engcupheni. Utshani basolwandle bungasiza ekulweni nokuguguleka kolwandle futhi bube yingxenye yezindawo ezinqamula amanzi ezivikela ugu ekuhlaseleni kweziphepho. Ukwehliswa kungabeka obala utshani basolwandle ekuminyanisweni, ekususweni noma ekubhujisweni.
Ngenhlanhla, ngedatha elungile, singakhawulela imiphumela emibi yokudonsa olwandle.
Ucwaningo luye lwabonisa ukuthi ngezinqubo zokuphatha ezifanele, imiphumela yokudoba olwandle ingakhawulelwa ekufihleni umsindo, izinguquko zokuziphatha zesikhashana kanye nezinguquko ekutholakaleni kwezilwane ezifuywayo.
Osonkontileka abadonsa kanzima bangasebenzisa ama-mini wave buoys e-Frankstar ukuthuthukisa ukuphepha nokusebenza kahle. Abasebenzisi bangafinyelela idatha yesikhathi sangempela yegagasi eqoqwe i-Mini wave buoy ukwazisa izinqumo zokuhamba/ukungahambi, kanye nedatha yengcindezi yamanzi angaphansi eqoqwe ukuqapha amazinga amanzi endaweni yephrojekthi.
Ngokuzayo, osonkontileka abambayo bazokwazi futhi ukusebenzisa okokusebenza kwezinzwa zasolwandle kwa-Frankstar ukuze kuqashwe ukungcola, noma ukuthi acwebe kangakanani noma acwebe kangakanani amanzi. Umsebenzi wokudonsa uvusa inqwaba yenhlabathi, okuholela ezilinganisweni eziphakeme kunezivamile ze-turbidity emanzini (okungukuthi ukwanda kokungaboni). Amanzi anodaka anodaka futhi afihla ukukhanya nokubonakala kwezitshalo nezilwane zasolwandle. Nge-Mini Wave buoy njengehabhu lamandla nokuxhumana, o-opharetha bazokwazi ukufinyelela izilinganiso ezivela kuzinzwa ze-turbidity ezinamathiselwe kuma-smart moorings ngokusebenzisa isixhumi esibonakalayo se-Bristlemouth sehardware esivulekile, esihlinzeka ngokusebenza kwe-plug-and-play kumasistimu enzwa yasolwandle. Idatha iqoqwa futhi idluliselwe ngesikhathi sangempela, okuvumela ukuqubuka kwe-turbidity ukuthi kuqashelwe ngokuqhubekayo ngesikhathi sokusebenza kokudonsa.
