Ingqumba yentlabathi yimfumba yesanti. Umntu udla ngokucinga ngeenduli ezinkulu zesanti kwindalo, umzekelo entlango okanye elunxwemeni. Iindunduma ezincinci zibizwa ngokuba ngamaripples.
Iingqumba zentlabathi zenziwa ngumoya ovuthuza intlabathi ibe yimfumba. Ngamanye amaxesha kukhula ingca apho. Kungoko kanye apho iindunduma zihlala ixesha elide. Iindunduma ezishukumayo zihlala zitshintshwa kwaye zityhalwa ngumoya.
Imbonakalo-mhlaba yeendunduma yaziwa eJamani, ngakumbi kunxweme loLwandle lwaseMantla. Apho iingqumba zentlabathi kukho umcu omxinwa phakathi konxweme nangaphakathi emhlabeni. Esi siqwenga sisuka eDenmark sidlula eJamani, eNetherlands, naseBelgium siye eFransi. Iziqithi ezikuLwandle lwaseWadden ubukhulu becala ziinduli zesanti.
Kodwa kukho iindunduma kumbindi welizwe eJamani. Azikho ncam iintlango apho, kodwa iindawo ezinesanti. Iingqumba zentlabathi zikwabizwa ngokuba ziindunduma zangaphakathi, ezi ndawo zibizwa ngokuba ngamathafa entlabathi aguqukayo. Ngokuqhelekileyo zihlala kufuphi nemilambo, kodwa kwakhona, umzekelo, eLüneburg Heath, naseBrandenburg.
Kutheni ezinye iindunduma zingavunyelwa ukuba kungenwe kuzo?
Iindunduma eziselunxwemeni zibalulekile ngenxa yezizathu ezininzi. Ke ngoko, ziindlela ezimxinwa kuphela ezikhokelela kwiindunduma ukusuka emhlabeni ukuya elunxwemeni. Iindwendwe kufuneka zihlale ezindleleni. Ucingo luhlala lubonisa apho ungavumelekanga ukuba uhambe.
Kwelinye icala, iindunduma zikhusela umhlaba elwandle. Xa umsinga uphezulu, amanzi anyukela kuphela kwiindunduma, ezisebenza njengedama okanye udonga. Yiyo loo nto abantu betyala ingca apho, ingca eqhelekileyo yaselwandle, ingca yeendunduma, okanye unxweme lwavuka. Izityalo zibamba iindunduma kunye.
Kwelinye icala, indawo yeengqumba zentlabathi ikwayindawo ekhethekileyo ngokwayo. Zininzi izilwanyana ezincinci nezinkulu ezihlala apho, amaxhama kunye neempungutye. Ezinye izilwanyana ngamacikilishe, imivundla, ingakumbi iintlobo ezininzi zeentaka. Umntu makangazincothuli izityalo okanye aphazamise izilwanyana.
Ezinye izizathu kukukhusela iinkqubo ze-bunker. Ebudeni beMfazwe Yehlabathi II, imikhosi yakha izakhiwo nezixhobo zokuzikhusela. Namhlanje zingamatye ezikhumbuzo kwaye akufanelekanga ukuba zonakaliswe. Ukongeza, amanzi okusela afunyanwa kwezinye iindawo zeendunduma.
Ukuba abantu babehambahamba apho okanye bamise intente, babezinyathela izityalo. Okanye zingena kwiindlwane zeentaka. Kananjalo awufuni ukuba abantu bashiye inkunkuma ejikeleze iindunduma. Nangona kukho isisongelo sezohlwayo, abantu abaninzi abahambisani nokuvalwa komsebenzi.
