\u2019n Proses van duisende jare het Saldanhabaai gevorm, maar niks het so \u2019n drastiese uitwerking op die Baai gehad soos ontwikkeling nie.<\/p>\n\n\n\n
Tydens die jaarlikse State of the Bay<\/i> het prof. Jacques Bezuidenhout, verbonde aan die Universiteit Stellenbosch, meer vertel oor die geografie van Saldanhabaai en die Langebaan-strandmeer.<\/p>\n\n\n\n
\u201cSaldanhabaai en die Langebaan-strandmeer is uniek. Saldanha is die grootste [natuurlike] hawe in Afrika en die hawe het tydens die Tweede W\u00eareldoorlog regtig tot stand gekom,\u201d verduidelik Bezuidenhout.<\/p>\n\n\n\n
Saldanhabaai was toe \u2019n bymekaarkompunt vir konvooie voordat hulle na Brittanje gevaar het. <\/p>\n\n\n\n
Die weermag het dus die eerste menslike ontwikkeling van die Baai bewerkstellig toe vars water van die Bergrivier af hierheen gepomp is.<\/p>\n\n\n\n
Hoewel die meeste baaie in die Wes-Kaap uit sediment\u00eare gesteentes bestaan, is Saldanhabaai die uitsondering. Hier is die Baai se gesteentes uit graniet gevorm, en dit is deel van die Kaapse granietgesteente.<\/p>\n\n\n\n
Die bekende klip agter Weskus Mall, wat in die volksmond die Jesus-klip genoem word, is \u2019n voorbeeld van die granietgesteentes, s\u00ea Bezuidenhout.<\/p>\n\n\n\n
Wind en water in die vorm van golwe het Saldanhabaai en die omliggende omgewing oor duisende jare gevorm.<\/p>\n\n\n\n
Ontwikkeling het ook \u2019n invloed op die geografie van die Baai, met die bou van die hawe wat \u2019n groot impak op die omgewing in die gebied gehad het.<\/p>\n\n\n\n
\u201cDie meeste van die vulgrond wat gebruik is om die hawe te bou, is deur middel van baggerwerk bekom. Volgens hul beplanning sou dit \u2019n jaar neem om die breekwater te bou, maar dit was te optimisties. Dit het hulle twee en \u2019n half jaar geneem,\u201d verduidelik hy.<\/p>\n\n\n\n
Dit het soveel langer geneem deels weens die kalkreet wat so hard soos sement was en bouwerk bemoeilik het. <\/p>\n\n\n\n
Bouwerk is uiteindelik in September 1976 voltooi. <\/p>\n\n\n\n
Oor die jare het die veeldoelige terminaal en die gebruik van die gebied vir die laai van ru-olie gevolg.<\/p>\n\n\n\n
Bezuidenhout verduidelik weens die baggerwerk, waar sediment van een deel van die Baai na \u2019n ander deel verskuif is, het die natuurlike proses in die baai verander.<\/p>\n\n\n\n
\u201cWat ons gevind het, is dat die diepte van die baai vanaf 1977 tot 2021 met gemiddeld 1,8 m toegeneem het. Dit is weens die kalkreet-vlak wat verwyder word. Dit is soos om die emalje van jou tande af te haal. \u2019n Proses wat oor duisende jare sou plaasvind, vind nou binne die bestek van vyf of tien jaar plaas,\u201d verduidelik hy.<\/p>\n\n\n\n
Die helling van die baai het ook verander en Bezuidenhout s\u00ea dit speel ook \u2019n rol in erosie in die gebied. Hy s\u00ea dis belangrik om die veranderinge aan Saldanhabaai vir enige toekomstige ontwikkeling in gedagte te hou.<\/p>\n","protected":false},"excerpt":{"rendered":"
