Ukugrumba olwandle kubangela umonakalo kwindalo kwaye kunokuba nefuthe elibi kwiintyatyambo nezilwanyana zaselwandle.

“Ukwenzakala okanye ukufa ngenxa yokungqubana, ukuveliswa kwengxolo, kunye nokwanda kokungcola zezona ndlela ziphambili apho ukugrumba okunokuchaphazela ngokuthe ngqo izilwanyana zaselwandle,” litsho inqaku elikwi-ICES Journal of Marine Science.

"Iziphumo ezingathanga ngqo zokugrumba emanzini kwizilwanyana zaselwandle zivela kutshintsho kwindawo ezihlala kuyo okanye kwixhoba lazo. Iimpawu zomzimba, ezinje nge-topography, ubunzulu, amaza, imisinga yolwandle, ubungakanani beenxalenye ze-sediment kunye noxinzelelo lwe-sediment olumisiweyo, zitshintshwa kukugrumba, kodwa utshintsho luyenzeka ngokwendalo ngenxa yeziganeko zokuphazamiseka ezifana namaza, amaza kunye nezivuthuvuthu."

Ukugrumba ingca kunokubangela umonakalo kwiingca zolwandle, nto leyo ekhokelela kutshintsho oluhlala ixesha elide elunxwemeni kwaye inokubeka uluntu oluselunxwemeni emngciphekweni. Iingca zolwandle zinokunceda ekuchaseni ukukhukuliseka kolwandle kwaye zibe yinxalenye yeendawo ezikhusela unxweme kwiinkqwithela. Ukugrumba ingca kunokubeka utyani lolwandle kwindawo yokuminxeka, ukususwa okanye ukutshatyalaliswa.
Ngethamsanqa, ngedatha echanekileyo, singayinciphisa imiphumo emibi yokugrunjwa kweentlanzi zaselwandle.
Izifundo zibonise ukuba ngeenkqubo zolawulo olufanelekileyo, iziphumo zokugrumba elwandle zinokukhawulelwa ekugqumeni isandi, utshintsho lwexesha elifutshane lokuziphatha kunye notshintsho ekufumanekeni kwexhoba.

Abakhi beenkampani zokutsala amanzi bangasebenzisa ii-mini wave buoys zaseFrankstar ukuphucula ukhuseleko lokusebenza kunye nokusebenza kakuhle. Abaqhubi banokufikelela kwidatha yamaza eqokelelwe yiMini wave buoy ukuze banike ulwazi ngezigqibo zokungahambi/ukungahambi, kunye nedatha yoxinzelelo lwamanzi angaphantsi komhlaba eqokelelwe ukujonga amanqanaba amanzi kwindawo yeprojekthi.

Kwixesha elizayo, abakhi bee-dredging baya kukwazi ukusebenzisa izixhobo zokuva amanzi zaselwandle zaseFrankstar ukujonga ukungcoliseka kwamanzi, okanye ukuba amanzi acacile okanye angabonakali kangakanani na. Umsebenzi wokuvalela amanzi uvuselela inani elikhulu lenkunkuma, nto leyo ebangela ukuba kulinganiswe ukungcoliseka kwamanzi ngaphezulu kunesiqhelo (oko kukuthi, ukungcoliseka kwamanzi okwandayo). Amanzi angcolisekileyo amdaka kwaye afihla ukukhanya kunye nokubonakala kwezityalo nezilwanyana zaselwandle. Njengoko iMini Wave buoy iyindawo yombane kunye nokunxibelelana, abaqhubi baya kukwazi ukufikelela kumlinganiselo ovela kwiisensa ze-turbidity ezincamatheliswe kwii-smart moorings ngokusebenzisa i-interface ye-hardware evulekileyo yaseBristlemouth, ebonelela ngokusebenza kwe-plug-and-play kwiinkqubo zokuva amanzi zaselwandle. Idatha iqokelelwa kwaye idluliselwe ngexesha langempela, ivumela ukungcoliseka kwamanzi ukuba kuhlale kujongwa ngexesha lemisebenzi yokuvalela amanzi.
