Water resources management in rice irrigation systems and improvement of ecological situation in rice growing river basins

Abstract

Water resources management in the rice irrigation systems in Kazakhstan as well as water conservation and its efficient use are associated with technological processes control factors such as irrigation efficiency, layout of rice bays and their terracing. Managing technological processes in rice systems is complex, since there are significant deviations in the technological parameters of rice systems from the optimal. Therefore, in order to properly manage these processes, it is necessary to know the impact, its direction, assess the results of these impacts and develop an appropriate scientific and information base. The paper considers the impact of rice bays layout quality and terrace on the water-salt regime of soils, rice productivity and irrigation rate. Also, it proposes improvements to parameters of rice systems, water conservation, environmental situation in areas of rice cultivation and water resources management in rice systems.

Scientific and methodological substantiation of measures for environmental management of upstream area Tupolangsky waterworks

“…Moreover, using the MASSCOTE technique (this is the search for a solution to improve irrigation management and operation and better user service) [6][7][8][9][10][11]. The necessary materials were taken from annual reports of the Regional Department of Water Management of the Surkhandarya Region, also irrigation and drainage expeditions.…”

Development of recommendations on partial transfer of land to gravity irrigation in zone of Bandyhan - I substandard pumping station with compensation of expenses from Tupolang reservoir

“…This year, the Tupolang-Karatag Canal Operation Department has carried out work to increase the capacity of the terminal part of the Akkapchigai canal to 15 m 3 /s, and work is underway to reconstruct the R-1 canal with an increase in capacity to 11-12 m 3 /s and bringing its route to the Bandyhan canal [4]. The scheme of irrigation of land from the Bandyhan canal, partly by gravity and partly with the help of the Bandyhan -II pumping E3S Web of Conferences 401, 01009 (2023) CONMECHYDRO -2023 https://doi.org/10.1051/e3sconf/202340101009 station, is shown in Figure 2.…”

Recommendations for reducing sanding process in water wells

“…Our practical research and analysis of available sources show that the water formation rate in water wells obeys the law of arithmetic progression along the length of the filter. In this case, the flow rate in the filter increases from bottom to top [17,18,19,20,21]. Depending on the particle size distribution, the soil particles are also lifted up and removed with the water due to the speed of the water.…”
