Indunduma yinqwaba yesihlabathi. Umuntu uvame ukucabanga ngamagquma esihlabathi amakhulu emvelweni, isibonelo ogwadule noma ogwini lolwandle. Izindunduma ezincane zibizwa ngokuthi ama-ripples.
Izindunduma zakhiwa umoya ophephula isihlabathi sibe yinqwaba. Kwesinye isikhathi kukhula utshani lapho. Yilapho kanye lapho izindunduma zihlala isikhathi eside. Izindunduma ezinyakazayo zilokhu zishintshwa futhi zidudulwa umoya.
I-Dune landscape yaziwa eJalimane, ikakhulukazi ogwini lolwandle olusenyakatho. Lapho izindunduma ziwumdweshu omncane phakathi kogu naphakathi nezwe. Lesi siqeshana sisuka eDenmark sidlule eJalimane, eNetherlands, naseBelgium siye eFrance. Iziqhingi ezisoLwandle iWadden ikakhulukazi yizindawo ezinendunduma.
Kodwa kunezindunduma ezimaphakathi nezwe eJalimane. Azikho ngempela izingwadule lapho, kodwa izindawo ezinesihlabathi. Izindunduma zibuye zibizwe ngokuthi izindunduma ezimaphakathi nezwe, lezi zindawo zibizwa ngokuthi izindunduma ezinyakazayo. Zivame ukutholakala eduze nemifula, kodwa futhi, isibonelo, eLüneburg Heath, naseBrandenburg.
Kungani ezinye izindunduma zingavunyelwe ukungenwa?
Izindunduma zasogwini zibalulekile ngezizathu ezimbalwa. Ngakho-ke, izindlela eziwumngcingo kuphela eziholela ezindundumeni ukusuka ezweni ukuya ogwini. Izivakashi kufanele zihlale ezindleleni. Uthango luvame ukukhombisa lapho ungavunyelwe ukuhamba khona.
Ngakolunye uhlangothi, izindunduma zivikela izwe olwandle. Emazingeni aphezulu, amanzi akhuphukela kuphela ezindundumeni, ezisebenza njengedamu noma udonga. Yingakho abantu betshala utshani lapho, utshani obuvamile basebhishi, utshani bendunduma, noma ibhishi liqhakaza. Izitshalo zibamba izindunduma ndawonye.
Ngakolunye uhlangothi, indawo yendunduma nayo iyizwe elikhethekile ngokwayo. Kuhlala izilwane eziningi ezincane nezinkulu, ngisho nezinyamazane nezimpungushe. Ezinye izilwane izibankwa, onogwaja, futhi ikakhulukazi izinhlobo eziningi zezinyoni. Umuntu akumele asiphule izitshalo noma aphazamise izilwane.
Ezinye izizathu ukuvikelwa kwezinhlelo ze-bunker. Phakathi neMpi Yezwe II, amabutho akha izakhiwo nezivikelo. Namuhla ziyisikhumbuzo futhi akufanele zonakaliswe. Ngaphezu kwalokho, amanzi okuphuza atholakala kwezinye izindawo ezinezindunduma.
Uma abantu bezulazula lapho noma bemise itende, babezinyathela izitshalo. Noma zingena ezidlekeni zezinyoni. Awufuni futhi abantu bashiye udoti eduze kwezindunduma. Naphezu kosongo lokujeziswa, abantu abaningi abahambisani nokuvinjelwa.
