Abstrak
Ushbu maqolada eroziyaga uchragan tuproqlarning releflarda qiyaliklarning tafsilotlari bo‘yicha ma’lymotlar keltirilgan. Hududda eroziya jarayonlarini boshlanganligi natijasida, tuproq yuzasidan kichik zarrachalar yuvilishi va ularni pastki qismlarga to‘planishi va u yerda kechayotgan jarayonni o‘zgartirgan. Sug‘orishdan keyin hosil bo‘lgan jo‘yaklarning bo‘ylama profilida o‘zgarishlarni sodir qiladi. Katta yonbag‘irlarda sug‘oriladigan dalalarda tuproq eroziyasining rivojlanishining bunday holati, jo‘yakning oxirgi qismiga 10 m masofa qolganda, suv oqimining tezligi va qiyalikning pasayishi bilan izohlanadi, bu esa cho‘kindilarni ushlab turishga yordam beradi hamda jo‘yakni oxirgi qismi tekislanadi.
