Zamonaviy suv xo‘jaligi va gidrogeologiya sohasida yer osti suvlari zaxiralarini baholash, ulardan oqilona foydalanish va muhofaza qilish masalalari eng dolzarb ilmiy-amaliy yo‘nalishlardan biri hisoblanadi. Tabiiy sharoitda g‘ovak muhit deyarli hech qachon bir jinsli bo‘lmaydi: turli litologik tarkibga, filtratsiya koeffitsiyentiga va suv sig‘imiga ega bo‘lgan qatlamlar bir-biri bilan gidravlik jihatdan bog‘langan holda murakkab ko‘p qatlamli sistemani hosil qiladi. Bunday sistemalarda filtratsiya jarayonini tavsiflashda faqat gidrogeologik parametrlarning fazoviy heterogenligini emas, balki yog‘in-sochin, bug‘lanish, nasos qudulari orqali suv olish, daryo va sug‘orish tarmoqlari bilan gidravlik aloqa kabi tashqi omillarning ta’sirini ham hisobga olish zarur.

Аннотация

Оценка запасов подземных вод, их рациональное использование и охрана являются одним из наиболее актуальных направлений управления водными ресурсами. В природных условиях пористая среда практически никогда не бывает однородной: слои с различным литологическим составом, коэффициентом фильтрации и водоотдачей, гидравлически связанные между собой, образуют сложную многослойную систему. При описании процесса фильтрации в таких системах необходимо учитывать не только пространственную неоднородность гидрогеологических параметров, но и влияние внешних факторов - атмосферных осадков, испарения, водоотбора через эксплуатационные скважины, гидравлической связи с реками и оросительной сетью.

Abstract

The assessment, rational use, and protection of groundwater resources are among the most pressing directions in water resource management today. Under natural conditions, a porous medium is almost never homogeneous: layers with different lithological composition, filtration coefficients, and storage capacity, hydraulically connected to one another, form a complex multilayer system. Describing filtration processes in such systems requires accounting not only for the spatial heterogeneity of hydrogeological parameters, but also for the influence of external factors - precipitation, evaporation, groundwater abstraction through production wells, and hydraulic connection with rivers and irrigation networks.
