Imifula iyindlela yokukhululeka ebukeka njengemigodi enokujula okukhulu ngokwanele, iyakhiwa, imvamisa, lapho igezwa ngamanzi. Imifula ibhekwa njengenkinga, njengoba ivela ezindaweni ezingalindelekile ezindaweni ezinamagquma nezicaba, ilulaza izimo zenhlabathi, iguqule isimo sendawo engaphansi, iphinde iphazamise nemvelo. Uma ubude beminye imihosha bungaba ngamamitha amaningana, abanye - balula ngamakhilomitha. Ngeminyaka yokwakheka, izihosha sezikhulile futhi zisencane. Ukuze uvimbele ukukhula kwabo, lapho nje kutholakala, kubalulekile ukuqinisa inhlabathi: tshala izihlahla, wethule umswakama owedlulele. Ngaphandle kwalokho, kunethuba lokulahlekelwa amahektha aphelele omhlaba ovundile.
Izizathu zokwakhiwa kwezigodi
Ochwepheshe bakhomba inani elikhulu lezimbangela zemifula. Lezi akuzona ezemvelo kuphela, kodwa futhi nezimbangela ze-anthropogenic. Okuyinhloko yilezi:
- ukulima;
- amanzi embhedeni womfula;
- ukuguguleka kwamanzi nomoya;
- ukubhujiswa kwemithambeka yemigodi nokunye ukudangala emhlabathini;
- ukusika izikhala eziluhlaza;
- ukulima amathafa, ukuwaphendula amasimu;
- ukungabi namandla okuphatha amadamu;
- ukuqoqwa kwekhava leqhwa ebusika;
- umswakama onganele ezindaweni ezomile, njll.
Isembozo semifino yisona sivikelo esikhulu ekwenziweni kwezihosha emhlabathini. Uma abantu benza noma yimuphi umsebenzi wezomnotho, ngenxa yalokho okungaveli ngaphansi komhlaba kanye nemihosha kungavela, kubalulekile ukuqeda lezi zizathu: ukungcwaba izimbobo, ukulinganisa inhlabathi, ukutshala izitshalo ezintsha, ukuguqula ukugeleza kwamanzi kuye kwenye indawo.
Izigaba zokwakheka komhosha
Esigabeni sokuqala, kuvela umgodi wamanzi, okungezansi kwawo kufana nobuso bomhlaba. Uma imbangela ingasuswa ngokushesha, isigaba sokuqala sesibili siyaqala. Phakathi nawo, ukujula emhlabathini kukhula ngokushesha ngosayizi, i-gully iyajula, ibanzi futhi ibe yinde. Imithambeka emikhulu neyingozi iba seweni.
Ngemuva kwalokhu kuza isigaba sesithathu. Ngalesi sikhathi, umhosha uthuthuka ubheke ngasemanzini. Imithambeka ye-pothole iba manzi kakhulu, idilika futhi iyawa. Imvamisa umhosha ukhula uze ufinyelele kungqimba lomhlabathi. Esigabeni sesine, lapho umhosha usufinyelele ubukhulu obukhulu, ukukhula kwawo kuyama. Ngenxa yalokho, le ndlela yokusiza yonakalisa noma iyiphi indawo. Cishe akukho zimila lapha, futhi izilwane zingawela ogibeni lwemvelo, futhi akubona bonke abameleli bezilwane abazokwazi ukuphuma kuzo ngaphandle kokulimala.
