The analysis of the hydrochemical regime of the rivers feeding the irrigated territories of agricultural land in the river basin is essential to develop scientifically based recommendations on the rational use of water and land resources. Anthropogenic influence on water and land resources in the basins of the rivers inevitably affects the change of surface water quality. A new method is proposed for analyzing the hydrochemical regime of the rivers based on three-dimensional (3-D) modelling of the spatio-temporal distribution of water mineralization along the length of the main river. This method allows to analyze the flow of pollutants into the river, identify the main causes of pollution and the formation of the hydrochemical regime of rivers.

Ер ва сув ресурсларидан оқилона фойдаланиш бўйича илмий асосланган таклифларни ишлаб чиқишда қишлоқ хўжалиги ерларининг суғориладиган ҳудудларидан ҳамда дарё ҳавзасидан тўйинадиган дарёларнинг гидрокимёвий режимини таҳлил этиш зарур. Дарёлар ҳавзаларидаги ер ва сув ресурсларига антропоген омиллар таъсири, ўз навбатида, юза сувларнинг сифати ўзгаришига олиб келади. Мақолада асосий дарёнинг узунлиги бўйича минерализация миқдорининг макон ва вақт бўйича тарқалишини уч ўлчамли модель асосида дарёларнинг гидрокимёвий режимини таҳлил қилишнинг янги методи таклиф этилади. Мазкур метод дарёларга ифлослантирувчи моддаларнинг келиб тушишини таҳлил қилиш, дарёлар гидрокимёвий режимининг шаклланиши ва ифлосланишининг асосий сабабларини аниқлаш имконини беради.

Для разработки научно обоснованных рекомендаций по рациональному использованию водных и земельных ресурсов необходимо проводить анализ гидрохимического режима рек, питающих орошаемые территории сельскохозяйственных земель в бассейне реки. Антропогенное влияние на водные и земельные ресурсы в бассейнах рек неизбежно влияет на изменение качества поверхностных вод. В статье предлагается новый метод анализа гидрохимического режима рек на основе трехмерного (3-D) моделирования пространственно-временного распространения минерализации воды по длине основной реки. Данный метод позволяет проводить анализ поступления загрязняющих веществ в реку, выявлять основные причины поступления загрязнений и формирования гидрохимического режима рек.
