Ushbu maqolada yon tomon qiyaliqlari har xil bo‘lgan donador gruntli trapetsoidal kanallardagi suv oqimining yuvmaslik tezliklarini aniqlashning yangi formulalari tavsiya etilgan. Tadqiqotning ilmiy yangiligi shundan iboratki, namlangan perimetrni asimmetrik holda hisoblash usuli ishlab chiqilgan va gidravlik radiusning aniqroq ifodasi taklif qilingan. Laboratoriya tajribalari oltita donador grunt turi va turli qiyalik nisbatlari uchun amalga oshirildi. Taklif etilgan formulalar asosida hisoblangan va eksperimental o‘lchangan yuvmaslik tezliklari o‘rtasidagi o‘rtacha nisbiy xatolik 4,2% ni tashkil etdi. Simmetrik formulada ushbu ko‘rsatkich 11,8% ga yetishi aniqlandi. Olingan natijalar sug‘orish kanallarini loyihalash amaliyotiga bevosita tatbiq etilishi mumkin.
