Item type: Item , THE PROBLEM OF FLUID FLOW FROM A CHANNEL WITH A SIDE OUTLET(Journal of Adaptive Learning Technologies, 2024-09-05) Babazhanov Yuldash Tilavovich; Hazratov Alisher Rahmatillo ugli; Babazhanova Iroda Yuldashevna; Zaripov Musliddin Bahodir ugliThe article investigates the process of water distribution along the canal routes. The forms of these channels that ensure vortex-free flow are determined. This problem is reduced to solving the issue of the flow of an ideal incompressible fluid in a channel with a side outlet. A jet model of planar fluid flow in a channel with a side outflow is proposed. Analytical formulas for velocity distribution before and after the outflow are obtained, which allow regulating water supply to consumers.Item type: Item , EVALUATING THE INFLUENCE OF IRRIGATED SOIL PHYSICAL PROPERTIES ON ITS SETTLING PROCESS(“Intellekt”, 2024-05-03) F.F.

To date, a large number of field and laboratory research data on the movement of groups in the world have been obtained. Attempts have been made by some authors to summarize this information, but so far they have not been able to obtain perfectly reliable results. Therefore, new suggestions are being made by researchers to improve the formulas previously obtained.Item type: Item , CALCULATION OF TOTAL CHANNEL EROSION IN COHESIVE SOILS(AMERICAN JOURNAL OF EDUCATION AND LEARNING, 2024-12-12) Bobomurodov Furkat Farkhod ugli; Khazratov Alisher Rahmatillo ugli; Azizov Shavkat Abdurakhmanovich; Tuychiyev Jasur ShokirovichThis article highlights the main theoretical and practical issues of calculating general erosion processes in cohesive soil channels. The dynamics of flow saturation with particles and its dependence on flow velocity, sediment concentration, and the physical properties of the soil are studied. Integral consideration of parameters such as flow, topography, geology, and other channelforming factors is included. The separation of soil under the influence of turbulent flow and the empirical relationships of this process are described. As a result of the research, mathematical models and calculation methodologies for assessing erosion processes in cohesive soils are proposed. The calculation of the free surface curve was carried out using nomograms based on the Hydoproject methodology. Hydraulic parameters of the channel were determined, and its profile was reconstructed based on this methodology.Item type: Item , CALCULATION OF THE FRICTIОN PАRАMETER IN THE UNSTEADY FLОW BОRDER LАYER(“Qishloq xоʼjaligi mahsulotlarini ishlab chiqarish samaradorligini oshırishda innovatsion texnika va texnologiyalardan foydalanishning muammoları va istiqbollari”, 2024-05-03) A.R.Rakhimov; Alisher, Khazratov Rahmatillo o'g'li; D.D.Dilshodova; N.J.Raimova; S.Kh.Kulmatov; I.O.SattorovThe pаper prоpоses empiricаl relаtiоnships fоr cаlculаting the frictiоn pаrаmeter оf а nоn-stаtiоnаry turbulent bоundаry lаyer, which is cruciаl fоr eаrth chаnnel cоnstructiоn, bаsed оn the findings оf the literаture study.Item type: Item , BOGʻLANGAN GRUNTLI KANALLARDA UMUMIY YUVILISHNI HISOBLASH(INNOVATSION TEXNOLOGIYALAR, 2024-12-15) Bobomurodov Furqat Farxod oʻgʻli; Mamatov Nurbek Ziyodullayevich; Hazratov Alisher Rahmatillo oʻgʻli; Xoʻjayorov Shaxzodbek Anvar oʻgʻliMazkur maqolada bogʻlangan gruntli kanallarda umumiy yuvilish jarayonlarini hisoblashning asosiy nazariy va amaliy masalalari yoritilgan.

Эта проблема обуславливается и еще разнообразием природных условий орошаемых территорий, неудовлетворительным управлением водными ресурсами различных функциональных уровней. Плодородие почв, мелиоративное состояние орошаемых земель и углубление экологических проблем на прямую связаны засолением земель, степенью минерализацией грунтовых вод и загрязнением поверхностных водоисточников. Для полного анализа мелиоративного состояния орошаемых территорий исследуемого объекта необходимо изучение элементов водно-солевого баланса. При этом отслеживается изменение количественных показателей доходной и расходной частей баланса за ряд лет и их текущее состояние. В этой статье авторами рассмотрено влияние внешней среды на процесс биосинтеза растений, в данном случае хлопчатника и получены аналитические решения для влажности, концентрации соли и биомассы, которые показывают взаимной связи параметров растения, почвы, влаги, степени минерализации и количество воды на развитие растенийItem type: Item , DETERMINATION OF THE KINETIC ENERGY COEFFICIENT IN THE ZONE OF LOCAL EROSION OF THE EARTHEN CHANNEL CONNECTED TO THE LOWER REACH(Universum, 2025-10-28) Eshev Sobir Samatovich; Isakov Alisher Nemat ugli; Yuldosheva Umida Temurovna; Usmonov Rivojiddin Nosir ugliThe study focuses on analyzing the kinetic energy of the water stream flowing from spillway structures and its potential to cause erosion in the downstream channel. When water is discharged through a spillway, a large amount of kinetic energy is generated, which can directly erode the channel bed and banks located behind the structure. This process poses a serious threat to the stability and durability of hydraulic structures. The research emphasizes the importance of protecting the downstream channel from erosion through appropriate engineering solutions. Special hydraulic calculation methods were applied to determine the flow velocity and energy distribution behind the spillway. Based on the obtained results, recommendations for effective energy dissipation and channel reinforcement are proposed. The study aims to enhance the safety, reliability, and efficiency of spillway structures by preventing erosion and maintaining the stability of the downstream channel.Item type: Item , ASSESSMENT OF ENERGY LOSSES IN NARROWING CHANNELS UNDER CONDITIONS OF UNSTEADY FLOW(Universum, 2025-10-28) Bobomurodov Furkat Farkhod ugli; Zaripov Musliddin Bahodir ugli; Khazratov Alisher Rahmatillo ugli; Kuvvatov Jobirbek Zokirjon ugliThis paper presents an improved hydraulic model for analyzing unsteady flow behavior in variable cross-section open channels, with particular focus on converging rectangular inlet chambers. The study aims to enhance the accuracy of hydraulic computation under non-stationary conditions by incorporating the influence of vortex structures and gradual contraction geometry. Experimental investigations were carried out using a laboratory model with a converging rectangular channel of 120 cm length, 80 cm inlet width, and outlet widths of 40, 35, 30, and 25 cm. Average flow velocity was maintained near 0.67 cm/s, and four discharge rates of 30, 25, 20, and 15 𝑚3/ℎ were analyzed. Flow velocities were measured using a micro-propeller current meter. The results showed that increasing flow discharge and shortening contraction length both intensify vortex formation. The proposed model improves flow prediction accuracy by up to 8% compared with classical steady-state approaches and provides recommendations for optimizing inlet chamber geometries in open-channel systems.Item type: Item , RESEARCH OF FLOW KINEMATICS IN THE LOCAL EROSION AREA OF THE LOWER BYEF OF THE STRUCTURE(Universum: технические науки, 2025-10-28) Eshev Sobir Samatovich; Karshiyev Rustam Jurayevich; Isakov Alisher Nemat ugli; Yuldosheva Umida Temurovna; Mamarasulov Sobir Rakhmonkul ugliThe presented article examines the determination of hydraulic conditions in the junction sections of bays during the design of water discharge hydraulic structures, which has important scientific and practical significance. In these areas, sharp changes in flow regime are observed, during which the flow transitions from a turbulent, i.e., supercritical, state to a calm, or subcritical state. It has been established that such a transition is possible only through the phenomenon of a hydraulic jump, which represents a complex hydrodynamic process. Reducing the excess energy of the flow is carried out by various forms of jumps - bottom or surface type, as well as by the method of free discharge of the jet. The correct choice of energy dissipation method contributesto the effective reduction of the destructive impact of the flow, ensures the longterm operational stability of the hydraulic structure, and increases its reliability and safety in various hydrological conditions.Item type: Item , АНАЛИЗ НЕСТАЦИОНАРНОГО ДВИЖЕНИЯ МНОГОФАЗНОГО ПОТОКА С ИСКУССТВЕННЫМ РАССЛОЕНИЕМ ПОТОКА(2025) Хужакулов Рустам; Турсунов Феруз Юлдошевич; Исломов Илхом МустоновичАннотация.

This affects the density and structure of the soil. After the pipeline is laid, the soil must be compacted. If the compaction is insufficient, the soil will loosen and distribute the load on the pipeline incorrectly. When installing the pipeline, attention should be paid to the processes of soil excavation, compaction and water flow.
