Dulmar guud oo ku saabsan Baararka Birta ee Barxadda ah
Biraha godan ee barroosinka waxaa lagu soo saaraa qaybo leh dherer caadi ah oo ah 2.0, 3.0 ama 4.0 m. Dhexroorka caadiga ah ee dibadda ee biraha godan waxay u dhexeeyaan 30.0 mm ilaa 127.0 mm. Haddii loo baahdo, biraha godan ayaa la sii wadaa iyadoo la isticmaalayo lawska isku xiran. Noocyo kala duwan oo qodis allabari ah ayaa la isticmaalaa iyadoo ku xiran nooca ciidda ama cufka dhagaxa. Bir godan ayaa ka fiican bir adag oo leh aag iskutallaab ah sababtoo ah hab-dhaqankeeda qaab-dhismeedka oo ka wanaagsan marka loo eego gariirka, wareegga iyo adkaanta foorarsiga. Natiijadu waa xasillooni sare oo gariir iyo dabacsanaan ah oo loogu talagalay isla xaddi bir ah.

Adeegsiga Ulaha Barroosinka Is-qodista
Sannadihii ugu dambeeyay, iyadoo baahida sii kordheysa ee taageerada farsamada dhulka, qalabka qodista ayaa si joogto ah loo cusbooneysiiyay loona horumarinayay. Isla mar ahaantaana, kharashka shaqada iyo kirada ayaa kordhay, shuruudaha muddada dhismahana way sii kordhayaan. Intaa waxaa dheer, isticmaalka ulaha barroosinka godan ee is-qoditaanka xaaladaha juqraafiyeed ee u nugul inay dumaan waxay leeyihiin saameyn aad u fiican oo barroosin ah. Sababahani waxay horseedeen codsi sii kordhaya oo baahsan oo ah ulaha barroosinka godan ee is-qoditaanka. Ulaha barroosinka godan ee is-qoditaanka waxaa inta badan loo isticmaalaa xaaladaha soo socda:
1. Loo isticmaalo sidii ul barroosin oo la adkeeyay: waxaa loo isticmaalaa xaaladaha sida jaranjarooyinka, qodista dhulka hoostiisa, iyo ka hortagga sabeynta si loogu beddelo fiilooyinka barroosinka. Ulaha barroosinka godan ee is-qoditaanka ayaa la qodaa ilaa qoto dheer ee loo baahan yahay, ka dibna waxaa la sameeyaa dahaarka dhammaadka. Ka dib marka la adkeeyo, xiisad ayaa la adeegsadaa;
2. Loo isticmaalo sidii tuulmooyin yaryar: Ulaha barroosinka ee is-qoda ayaa la qodi karaa oo hoos loo qodi karaa si loo sameeyo tuulmooyin yaryar, oo si caadi ah loogu isticmaalo aasaaska munaaradaha warshadaha tamarta dabaysha, aasaaska munaaradaha gudbinta, aasaaska dhismaha, aasaaska tuulmooyinka derbiga ee la hayo, aasaaska tuulmooyinka buundada, iwm.
3. Waxaa loo isticmaalaa ciddiyaha ciidda: waxaa badanaa loo isticmaalaa taageerada jiirada, iyadoo la beddelayo ulaha birta ee caadiga ah ee bar-tilmaameedka, waxaana sidoo kale loo isticmaali karaa taageerada jiirada qotoda dheer ee godka salka;
4. Loo isticmaalo musmaarrada dhagaxa: Meelaha qaar ee dhagaxa ama godadka leh cimilo daran oo dusha sare ah ama horumarinta kala-goysyada, ulaha barroosinka ee godan ayaa loo isticmaali karaa qodista iyo qodista si loo isku xidho baloogyada dhagaxa si loo hagaajiyo xasilloonidooda. Tusaale ahaan, meelaha dhagaxa ah ee waddooyinka waaweyn iyo tareenada ee u nugul inay dumaan waa la xoojin karaa, meelaha tuubooyinka caadiga ahna waxaa sidoo kale lagu beddeli karaa xoojinta meelaha daloolka dabacsan;
5. Xoojinta aasaasiga ah ama maaraynta masiibooyinka. Marka wakhtiga taageerada ee nidaamka taageerada juqraafiyeed ee asalka ah uu kordho, qaab-dhismeedka taageeradan waxaa laga yaabaa inay la kulmaan dhibaatooyin u baahan xoojin ama daaweyn, sida isbeddelka jiirada asalka ah, degitaanka aasaaska asalka ah, iyo kor u qaadista dusha sare ee wadada. Ulaha barroosinka godan ee iskood u qodaya ayaa loo isticmaali karaa in lagu qodo jiirada asalka ah, aasaaska, ama dhulka wadada, iwm., si loo qodo loona xoojiyo dildilaaca, si looga hortago dhacdooyinka masiibooyinka juqraafiyeed.
