Kam bog‘langan grunt o‘zanli irrigatsiya kanallarida o‘zan deformatsiyasini ishonchli prognozlash kanallarni gidravlik hisoblash, rekonstruksiya qilish hamda texnik jihatdan ishonchli ekspluatatsiya qilishning muhim shartlaridan biridir. Biroq oqim tarkibida muallaq oqiziqlar bilan bir qatorda kam miqdordagi bog‘langan zarrachalarning mavjudligi an’anaviy oqim tashuvchanlik qobiliyatini hisoblash usullarini qo‘llashni murakkablashtiradi. Mazkur tadqiqotda Ackers–White, Engelund–Hansen, Yang va Laursen–Copeland oqim tashuvchanlik qobiliyatini hisoblash usullarining kam bog‘langan grunt o‘zanli kanallarda o‘zan deformatsiyasini prognozlashdagi qo‘llanish imkoniyatlari HEC-RAS gidravlik modeli yordamida qiyosiy baholandi. Tadqiqot obyekti sifatida Amu–Buxoro mashina kanali tanlanib, 2023-yilda tabiiy-dala sharoitida o‘lchangan gidravlik va oqiziq parametrlaridan modelni qurish hamda tekshirishda foydalanildi. Modellashtirish natijalari kanalning kuzatilgan o‘zan deformatsiyasi va ekspluatatsion loyqa bosishi ma’lumotlari bilan taqqoslandi. Tadqiqot natijalari qo‘llanilgan usullar o‘zan deformatsiyasini sezilarli darajada turlicha baholashini ko‘rsatdi. Ackers–White, Yang va Engelund–Hansen usullari deformatsiya hajmini nisbatan yuqori baholagan bo‘lsa, Laursen–Copeland usuli tabiiy kuzatuv natijalariga eng yaqin qiymatlarni berdi. Tadqiq qilingan 2,4 km uzunlikdagi kanal uchastkasi uchun ushbu usul bo‘yicha qayta modellashtirish natijasida umumiy deformatsiya hajmi 39 091 m3 yoki 16 288 m3/km ni tashkil etdi, bu esa ekspluatatsion kuzatuvlarda aniqlangan 11 277 m3/km o‘rtacha loyqa bosishi qiymatiga eng yaqin natija bo‘ldi. Tadqiqot natijalari tabiiy-dala kuzatuvlari va HEC-RAS gidravlik modellashtirishni birgalikda qo‘llash kam bog‘langan grunt o‘zanli irrigatsiya kanallarida o‘zan deformatsiyasini prognozlash uchun oqim tashuvchanlik qobiliyatini hisoblash usullarini tanlashda ishonchli yondashuv ekanligini ko‘rsatdi.
