SUG‘ORILADIGAN YERLARDA SUV–TUZ ALMASHINUVI VA SIZOT SUVLARI REJIMINI MATEMATIK MODELLASHTIRISH: MELIORATIV HOLATNI PROGNOZLASHNING ILMIY ASOSLARI
Abstract
Maqolada sug‘oriladigan yerlarning meliorativ holatini belgilovchi asosiy jarayonlar — ildiz zonasidagi suv balansi, tuzlarning konvektiv-dispersiv ko‘chishi, sizot suvlarining sathi va mineralizatsiyasi hamda drenaj samaradorligi — yagona matematik tizim sifatida tahlil qilinadi. Richards tenglamasi, adveksiya-dispersiya tenglamasi va yer osti suvlari balansi asosida dala va massiv miqyosidagi prognozlash yondashuvi taklif etiladi. HYDRUS-1D, SWAP va MODFLOW 6 modellarining vazifalari, kalibrlash va validatsiya talablari taqqoslanadi. Qashqadaryo sharoitida suv taqchilligi, sayoz/minerallashgan sizot suvlari va drenaj holati birgalikda hisobga olinmasa, sho‘rlanish prognozi xatoligi oshishi ko‘rsatiladi. Maqola yangi dala tajribasi emas, balki rasmiy hujjatlar va nashr etilgan ilmiy manbalarga tayangan analitik-tahliliy ishdir.
