Ushbu maqolada trapetsiyasimon ko‘ndalang kesimga ega bo‘lgan ochiq kanalda tub osti va muallaq oqiziq sarflarini hisoblashning zamonaviy nazariy asoslari va amaliy usullari bayon etilgan. Har xil qiyalikka (m1 ≠ m2) ega bo‘lgan donador grunt asosidagi kanallar uchun Meyer-Peter va Müller (1948), Bagnold (1966), Engelund-Hansen (1967) hamda Rouse-Einstein va Van Rijn (1984) usullari qiyosiy tahlil qilingan. Manning tenglamasi asosida gidravlik hisob-kitoblar amalga oshirilgan, Shields parametri va Rouse sonining oqiziq harakatiga ta’siri o‘rganilgan. Hisoblash algoritmi dasturiy vosita yordamida sinab ko‘rilgan va b=15 m, h=5 m, m1=m2=3, i=0,0003, d=0,5 mm bo‘lgan misolda jami oqiziq sarfi 6,81×10⁻³ m³/s ekanligi aniqlangan.
