Evaluation of sedimentation of water reservoirs with modern technologies

Abstract

When dams are built, sedimentation accumulation starts in high-fuzzy; after filling of dead volume happens, blurring of useful volume, and the efficiency of the reservoir decreases. In this research, the Chartak reservoir in the Namangan region. In this study, the ArcGIS application was used with the ArcMap program. Originally Sentinel 2 Satellite images were downloaded free of charge from Glo Vis US official website. The unstable reservoirs were selected for the length of the reservoir. For each reservoir, the dependence of the water level on the flow rate was calculated, thus analyzing the sediment movement. The research results showed that 10 control points were taken, where Q was the same. In the first control point, in which all value was a bit lower than others, Q was 5, followed by 310 in B, 3.4 in H, omega had 1081.3, and 4.6 in ϑ.

Development of the constructive scheme and 3D model of the smart corn-seed grader machine

“…(12) based on the expression Нb =0.08 m, g=9.8 m/s2 and according to the physical and mechanical properties of corn, lк =0.262 m, dк = 0.0386 m, mc =0.131 kg and fк =0.42 [ 10], taking into account the values, a graph of the change in the width of the intake part of the fuel cell at different values of performance was constructed (Fig. 2).…”

“…Because when the number of livestock and poultry increases, the requirement rises for forage and feedstuffs too. Especially, grain and silage of the corn are always used as productive feedstuff in countries of the world where livestock and poultry branches are developed [5][6][7][8][9][10][11].…”

Raising calves using cold methods at an early age

“…One of the fundamental factors for increasing the production of livestock products is the organization of proper intensive rearing of replacement young stock; the system for rearing young stock should ensure a more complete realization of the hereditary inclinations of animals in the process of their growth and development, which are secretly interconnected. Their ratio determines the type of animal, which in turn depends on the conditions of its individual development [1,2,3,4].…”

The importance of soil and water for increasing the strength of ceramic products

“…Data reflecting the physical and chemical and physical and mechanical properties of the soil used as a raw material for the production of ceramic products, data reflecting the fundamental difference between electro activated water obtained on the basis of the proposed technological method from ordinary water, and the main purpose of the proposed data based on them and considerations for its implementation, which can be taken as a basis [3,4].…”
