The paper presents the results of field research in the area of the damless water intake of the KMC on the Amudarya River. The article developed the optimal route and boundaries of the pioneer digging location, depending on the area of the main stream of the river relative to the point of the damless intake. It also provides hydraulic calculations for improving the condition of a damless water intake and recommendations for the rational use and placement of a dredgers fleet when laying a route of a ditch and cleaning it.

The article presents structural and technological solutions in the revision of the constructive paradigm that has been in effect for many decades, associated with the use of traditional structural materials (metal, concrete, reinforced concrete) in the creation of various types of protective devices for water intakes of urban water management systems. The paper notes that the currently existing various types of water intake structures made of traditional materials do not meet modern requirements for environmental acceptability indicators and, accordingly, cannot provide the necessary environmental safety. As a result of the conducted research, an environmentally safe bio positive design for protecting the water intake structure of urban water management systems in the form of a soft floating structure made of high-strength synthetic fabric materials, is proposed. Calculations of structural elements of a soft surfaced structure are given.

The paper analyzes the dynamics of planned and deep deformations on the section of the Amudarya River in the area of the damless water intake in the main structure of the Karshi Main Canal-KMC. The results of field studies of the state of the canal situation of the Amudarya River at the site of a damless water intake are studied. The course of riverbed processes in the riverbed is studied. Recommendations for improving water intake conditions have been developed. According to the results of the field survey and the study of the head section of the supply canal, the state of the Amudarya riverbed in the water intake zone was assessed. The results of surveys of the hydraulic and pumping modes of sediments of the Amudarya River in the area of the damless water intake are analyzed and summarized. The results of field studies of the canal situation of the Amudarya River in the water intake area in the Amudarya River KMC in the area of the Karshi head water intake are studied. The riverbed situation is not characterized by constant hydraulic characteristics over time for the same water flow rate, i.e. with the same water horizon marks, the flow rates may differ from each other by about half, and with the same flow rates, the horizon marks may vary up to ± 0.6 m. This is explained by the extreme instability and high mobility of the canal, and large deformations of the canal occur in a short time. The hydraulic regime of the river is characterized by a significant redistribution of speeds, depth and width of the flow. The range of their changes is within: Maximum speed >Vmax =2…5 m/s; average speed Vav = 0.5…2.5 m/s; depth H max = 4…14 m, Hav = 1…5 m; width B = 300…2000 m; slope i = 0.00016…0.0003. It is established that the characteristic feature of the river is that at a constant flow can have different average velocities depth and width, for example, when Qw = 1000 m3/s, respectively, v = 0.6…1.7m/s, B = 180…1030m, Hav = 1.1…4.3m.

The paper will present a technical analysis of the performance of the Heat Pumps (HP) installed in the domestic water pipe network for a big city scale. The HP integration scheme predicts the domestic water flow as a heat source and the district heating as a heat sink. The technical factors which influence on the estimated thermal power and performance of HP unit will be identified. Additionally, the pros and cons of HP operation in water intake will be determined. The analysis will be based on long-term measurement data from Glogow city.

This paper aims to assess the feasibility of applying Reverse Osmosis (RO) technology at MN Port. Hydro-oceanography analysis was performed to understand sea conditions in the proximity of MN Port and to determine water intake point. Furthermore, design analysis was also conducted to determine the most suitable RO design to be applied. Based on the hydro-oceanography analysis, the study area is generally shallow water areas with the depth ranges from 2-10 meters, and the type of tide is diurnal tide. The speed and direction of ocean currents range from 0.01-0.06 m/s with the dominant direction trending northeast and north. Based on the port development plan and hydro-oceanography analysis, it is recommended that the water intake point is at the north of the port. The results obtained from several analyses show that RO technology can be applied at MN Port.

In paper, researches of riverbed and hydraulic processes at the water intake from mountain rivers are observed. Classification of designs of the mountain water intake structures, based on continuity signs is offered. Perfecting of base designs of water intake structures of a mountain-foothill zone and means of their hydraulic automation is carried out. The technological, theoretical and experimental substantiation of parameters of basic elements of these designs with a glance of hydromorphometric characteristics of the mountain rivers is given. Complex hydraulic researches of kinematic characteristics and carrying ability of a two-phase stream on water intake structures are executed. Bases of a technique of engineering calculation of the offered designs of water intake structures and the recommendation of their designing and maintenance in various hydrological regimes are developed.
