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 ekuchera pamhuka dzemugungwa anobva mukushanduka kwenzvimbo yadzo yemuviri kana mhuka dzadzo. Zvimiro zvemuviri, senge topography, kudzika, masaisai, mafungu emvura, sediment particle size uye yakamiswa sediment concentrations, inochinjwa nekudonhedza, asi shanduko dzinongoitikawo zvechisikigo nekuda kwezvinoitika zvinovhiringa zvakaita semafungu, masaisai nemadutu.
Kudonhedza kunogonawo kukanganisa huswa hwemugungwa, zvichikonzera shanduko dzenguva refu mumahombekombe egungwa uye zvinogona kuisa nharaunda dzemumahombekombe panjodzi. Uswa hwegungwa hunogona kubatsira kudzivirira kukukurwa kwemahombekombe uye kuita chikamu chemvura inoputika inodzivirira mahombekombe kubva kune dutu. Kudonhedza kunogona kufumura mibhedha yehuswa hwegungwa pakukachidzwa, kubviswa kana kuparadzwa.
Neraki, neiyo data chaiyo, 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 kuonekwa 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.
