Igikonoshwa nigituba ubushyuhe bugizwe ahanini nigikonoshwa, igituba bundle, urupapuro rwumutwe hamwe numutwe. Muri byo, amazi amwe (ubusanzwe akonje akonje) atembera muruhande rwigituba, naho andi mazi (ubusanzwe amazi ashyushye) atemba kuruhande rwigikonoshwa. Bitewe nubushuhe butandukanye hagati yibi byombi, ubushyuhe bwimurwa buva mumazi yo hejuru - mumazi yubushyuhe bwo hasi -, bityo bigatuma habaho guhanahana ubushyuhe.
By'umwihariko, iyo amazi ashyushye yinjiye mugikonoshwa, ubushyuhe bwayo bwimurirwa mumazi akonje muruhande rwigituba binyuze murukuta rwigituba. Ubu buryo bwo guhererekanya ubushyuhe ntabwo bukora neza, ariko kandi burashobora kugenzura neza ubushyuhe bwamazi. Mubyongeyeho, igikonoshwa noguhindura ubushyuhe birashobora kandi gushushanywa nk - pass imwe cyangwa inyubako nyinshi - zinyuze muburyo bukenewe kugirango zuzuze ubushyuhe butandukanye.
