The article gives the method of calculation of water storages dam at hydro technical accidents. From natural disasters floods (flooding of water in the area and settlements) by the frequency of occurrence of the phenomenon, the area of distribution and the annual material damage ranked first. Moreover, in recent years, the world has seen an increase in the number and extent of floods and the associated social and economic losses. Both at present and in the foreseeable future, floods as a natural disaster cannot be completely prevented everywhere and everywhere, they can only be weakened, localized and with timely warning to minimize material damage. Therefore, one of the largest floods in recent years, that occurred in the West Kazakhstan region in the spring of 2011 and which took place without casualties, resulted in the allocation of more than 19 billion tenge in damage recovery from damage. Unplanned and inconsistent with general measures during floods and floods, the descent of these reservoirs can exacerbate the effects of flooding. The technical condition of the channel dams is especially dangerous. In case of possible accidents on these dams, many settlements, thousands of enterprises, millions of hectares of agricultural land can get into the affected area. Based on the results of full-scale leveling surveys, forecasting calculations of the breakthrough of the water reservoir dams of Bartogay, Kapshagay and Kurty hydrounits have made. Attached graphics show a dependence of water consumption at the dam breakthrough on the distance from the dam gates.

In the Address to the people of Kazakhstan dated January 30, 2017, the President of the Republic of Kazakhstan emphasized the need for technological modernization of economic sectors. In connection with this task, the Government of the Republic adopted the State Program for the Development of the Agro-Industrial Complex of the Republic of Kazakhstan for 2017-2021, aimed at solving urgent problems of the water sector of the economy [1]. The reason for climate change is the dynamic processes on Earth, external influences, such as fluctuations in the intensity of solar radiation, and, more recently, human activities. The article presents a study assessing the water resources of the Asa River. Water intake and water supply, formation and occurrence of groundwater level, condition of collector-drainage water, mineralization. The article given methods and solutions for the disposal of water resources.

Natural conditions in North and Central Kazakhstan and the energy potential of chestnut soil testify to the efficiency of agriculture, especially on irrigated lands. The humus horizon of chestnut soils is 35–50 cm, and the humus content is 3.0–3.5%. The majority of the humus (75%) is contained in a half-meter layer, which emphasizes the short humus level. The phosphorus content, both gross and mobile, is very low at 0.98–0.031%. Potassium is in elevated amounts. Soils are most susceptible to the application of nitrogen–phosphorus fertilizers. According to the mechanical composition, chestnut soils are predominantly lightly loamy, light clays with substrates of souses. Salinization is low, with a salt content in the 0–100 cm soil layer of 0.10–0.20%. The mass of the arable soil layer is 1.3–1.4 g/cm3. Deep plowing and loosening of soils improve the water and nutrition regime, creating good conditions for arid agriculture. With deep autumn plowing up to 30 cm, the accumulation of sediment and spring meltwater reaches 1200–1500 m3/ha more than in spring disposal. Deep plowing ensures absorption of irrigation water, eliminates run-off during irrigation, and reduces the number of crops requiring extra irrigation. In an average dry year, at 50% water availability and 70% soil moisture content (MC), the number of irrigations is 4, and the irrigation rate is 300–470 m3/ha; at 60% MC, 2 irrigations are performed, and the irrigation rate is 600–650 m3/ha. On irrigated land, the yield of cereals is 2.8–2.6 t/ha; perennial grasses, 3.0–4.5 t/ha; potatoes, 23.2–24.1 t/ha; carrots, 35.0–40.0 t/ha; and cabbage, 50.0–75.0 t/ha.

Electrochemical methods have been increasingly gaining popularity in the field of wastewater treatment. However, the performance of these methods can be highly affected by the polarity direction as determined by the electrodes arrangement (anode to cathode or cathode to anode); as well as the characteristics of the wastewater to be treated as determined by the type of wastewater. The presented research work investigated the relationship between polarity direction and the removal of pollutants from poultry slaughterhouse wastewater using titanium and aluminium electrode materials. In the first case, the wastewater was exposed to the Ti (anode)-Al (cathode) combination, whereas in the second case the wastewater was subjected to the Al (anode)-Ti (cathode) arrangement. The two cases were designed to see if the polarity direction of the chosen electrode materials affected the removal of pollutants. The removal efficiencies were computed as a ratio of the remaining concentration in the treated effluent to the concentration before treatment. It was observed that the production processes generate highly fluctuating wastewater in terms of pollution loading; for instance, 422 to 5340 Pt-Co (minimum to maximum) were recorded from color, 126 to 2264 mg/L were recorded from total dissolved solids, and 358 to 5998 mg/L from chemical oxygen demand. Also, the research results after 40 min of retention time showed that both electrode arrangements achieved relatively high removal efficiencies; Whereby, the aluminium to titanium polarity achieved up to 100% removal efficiency from turbidity while the titanium to aluminium polarity achieved a maximum of 99.95% removal efficiency from turbidty. Also, a similar phenomenon was observed from total dissolved solids; whereby, on average 0 mg/L was achieved when the wastewater was purified using the aluminium to titanium arrangement, while on average 2 mg/L was achieved from the titanium to aluminium arrangement. A little higher removal efficiency discrepancy was observed from ammonia; whereby, the aluminium to titanium arrangement outperformed the titanium to aluminium arrangement with average removal efficiencies of 82.27% and 64.11%, respectively.
