Marine dredging inokonzeresa kukuvadzwa kwezvakatipoteredza uye inogona kuva nekascade yekukanganisa kwakashata pamaruva emugungwa nemhuka.
“Kukuvadzwa mumuviri kana kufa nokubondera, kugadzirwa kworuzha, uye kuwedzera kwenyonganyonga inzira huru idzo kuchera kunogona kukanganisa zvakananga mhuka dzomugungwa,” inodaro imwe nyaya iri muICES Journal of Marine Science.
"Mamiriro asina kunanga ekudonha pamhuka dzemugungwa anobva mukushanduka kwenzvimbo yazvo kana mhuka yadzinenge yabata." Mamiriro emuviri, senge topography, kudzika, masaisai, mafungu emvura, saizi yepasi uye kunyungudika kwepasi, zvinochinjwa nekudonha, asi shanduko dzinongoitikawo zvega nekuda kwekuvhiringidza zviitiko zvakaita semafungu, masaisai nemafungu.
Kudonhedza kunogonawo kukanganisa huswa hwemugungwa, zvichikonzera shanduko dzenguva refu mumahombekombe egungwa uye zvinogona kuisa nharaunda dzemumahombekombe panjodzi. Huswa hwegungwa hunogona kubatsira kudzivirira kukukurwa kwemahombekombe uye kuita chikamu chemvura inoputika inodzivirira mahombekombe kubva kune dutu remhepo. Kudonhedza kunogona kufumura mibhedha yehuswa hwegungwa pakukachidzwa, kubviswa kana kuparadzwa.
Neraki, neiyo data chaiyo, isu tinogona kudzikisira iyo yakaipa mhedzisiro yekudzvova kwemugungwa.
Zvidzidzo zvakaratidza kuti nemaitiro ekutonga akakodzera, mhedzisiro yekudonha kwemugungwa inogona kugumira kune ruzha masking, shanduko yenguva pfupi yemaitiro uye shanduko mukuwanikwa kwemhuka.
Dredging makondirakiti anogona kushandisa Frankstar's mini wave buoys kuvandudza kuchengetedzwa kwekushanda uye kugona. Vashandisi vanogona kuwana chaiyo-nguva wave data yakaunganidzwa neMini wave buoy kuzivisa go/no-go sarudzo, pamwe nepasi pemvura yekumanikidza data inounganidzwa kuti itarise huwandu hwemvura panzvimbo yeprojekiti.
Mune ramangwana, dredging makondirakiti achakwanisawo kushandisa Frankstar's marine sensing midziyo yekutarisa turbidity, kana kujeka kana opaque mvura. Basa rekudonhedza rinomutsa huwandu hukuru hwesediment, zvichikonzera kukwira kupfuura kwakajairwa kuyerwa kwemvura mumvura (kureva kuwedzera kupenya). Mvura ine turbid ine madhaka uye inovharidzira chiedza uye kuoneka kwemaruva emugungwa nemhuka. Iine iyo Mini Wave buoy sehubhu yesimba uye yekubatanidza, vashandisi vanozokwanisa kuwana zviyero kubva kune turbidity sensors zvakanamirwa kune smart moorings kuburikidza neBristlemouth's yakavhurika hardware interface, iyo inopa plug-uye-kutamba mashandiro emarine sensing masisitimu. Iyo data inounganidzwa uye inofambiswa munguva chaiyo-nguva, ichibvumira turbidity kuti irambe ichitariswa panguva yekudhirowa mashandiro.
