Hydrocarbon pollution of the water surface is one of the most important environmental problems in the Caspian Sea. There are ongoing developments in the identification of contamination pollution using remote sensing data for environmental situations. In recent years, there has been a significant increase in satellite data and, consequently, an opportunity to increase the frequency of observations. The ability to handle increased amounts of data can be achieved through cloud-based processing. The purpose of this work was to update oil spill monitoring technology by utilizing advanced computing resources based on the Google Earth Engine (GEE) platform and radar satellite images Sentinel-1. An oil spill detection technology was developed by the study using only data archives available in the GEE environment.

The article estimates the number of hydrological observation points taking into account the minimum density of their location and in accordance with WMO recommendations. The territories of Kazakhstan, distinguished by a great variety of climatic conditions and natural zones, have different water availability and require separate norms in the organization of observation points in river basins, known water management regions of the republic. For each river basin, the areas of physiographic regions belonging to different natural zones, including drainless areas, were calculated, which amounted to more than 700 thousand km2. As a result of the calculation, the total minimum number of hydrological posts for the whole country was justified to be 500. However, with economic growth, this number should be increased in accordance with the developed principles and territorial zoning for more effective water resources management.

The article presents materials from our own research on the study of the distribution of the mineralization, ionic composition, hardness, dissolved gases and pH values in various components of the river ecosystem of the Kazakhstan part of the Ertis river basin in the summer of 2023. It has been established that the water of the Black Ertis river is ranked in terms of mineralization to ultra-fresh, the value of total hardness – to soft, the content and ratio of the main ions - to the carbonate class, calcium group, the second type. Within the Pavlodar region, the concentration of the main salt-forming ions in the water of the Ertis River increases on average by 1.7...2.4 times, the water becomes fresh, the Alekin water index remains CCaII throughout the entire flow. The mineralization of water in the floodplain lakes Orlovskoye, Staritsa, Kurkol differs little from the water of the river Irtysh. The value of all studied indicators in the water of the Ertis River, its tributaries and lakes does not exceed the maximum permissible concentration. The water of all studied water bodies, with the exception of the storage lake Balkyldak, in terms of the content of standardized main ions and mineralization, belongs to quality class 1, is suitable for all types of water use and corresponds to “very good” quality. The wastewater storage tank Balkyldak has water of high salinity (19.42 g/dm3), very hard, highly metamorphosed sodium chloride composition of the third type and it can be recommended for the extraction of bischofite, halite and gypsum.

Characteristics of the space and time changes in the amount of precipitation in the Kura-Aras lowland were studied in the research paper. The precipitation data of the hydrometeorological station covering a decade from 1992 to 2022 was utilized in the analyses. To conduct research, the mathematical-statistical and cartographic methods were used. According to the conducted research, the amount of precipitation in the Kura-Aras lowland is 310 mm. 40% of the total amount of precipitation rains during the warm semi-period, while 60% falls in the cold semi-period in the lowland. The amount of precipitation decreases from the coastal areas to the plains during the cold, while in the warm period, this process occurs oppositely. It was determined that atmospheric precipitation decreased in January, March, April, May, June, August, October, November and December, and this indicator increased in February, July and September. The annual indicator of the amount of precipitation in the plain decreased by 10% during the years 1991-2022 compared to the base quantity (1961-1990). 18% of the total precipitation was in the range of 10-19 mm, and 16% was in the range of 20-29 mm. Compared to the norm, in the period 1991-2022, in the Kura-Aras lowland, a 19% decrease was recorded in monthly recurrences of precipitation above 50 and 60 mm, and a 15% decrease in precipitation above 70 mm. The research results can be used in the establishment of novel economic areas in the lowland, in the development of maps, economic assessment and mitigation measures against climate change.

The patterns of formation of the average annual runoff in the basin of the Oba River and the rivers of the Kalbinsky Range were studied, meteorological characteristics were analyzed - average annual air temperatures and annual precipitation according to weather stations in Eastern Kazakhstan. Trends in changes in hydrometeorological indicators, and primarily the norms of these characteristics in conditions of climate warming, have been identified. The average annual water consumption of various water supplies in the modern period has been calculated. The analysis showed that over the long-term period since 1980, the annual flow of the rivers in question has decreased in the river basin. Both are 10.6% and 2.7% of the left bank tributaries of the Ertis. It should be noted that the emerging trend of increasing annual precipitation and average annual water flows of the rivers on the left bank of the Ertis since the beginning of 2010 may subsequently become stable, and in the future should lead to an increase in precipitation in the territory and the flow of the right-bank tributaries of the Ertis.

The study of thermal inversion layers in the atmosphere plays an important role in understanding various atmospheric processes and solving environmental and meteorological problems. This work is devoted to evaluating the potential of thermal inversion layer analysis using ERA5 reanalysis data in the nearground layer as an alternative to the limited availability of aerological stations.The characteristics of inversions calculated using ERA5 reanalysis data and radiosonde data from the Karaganda Aerological Station for the period from 2012 to 2021 were compared. General inversions occur most often in January (15...18 times), while in spring and autumn, the average monthly number of cases is 4...10. In the summertime, surface inversions occur most frequently, with a mean monthly value of up to 25 times. The intensity of different surface inversions varies between -1 °C ... -9 °С. The results of the study showed a close similarity between the ERA5 reanalysis data and the radiosonde data. This indicates the suitability of the reanalysis data for studying thermal inversions. This study contributes to the development of knowledge in atmospheric pollution, weather forecasting, aviation meteorology, and the development of climate models by using reanalysis data to study inversion phenomena.

In the research work, the peculiarities of the spread of a meteorological phenomenon dangerous for agriculture – the dry wind in the territory of Eastern Kazakhstan are considered. To achieve this goal, on the basis of long-term data, favorable conditions for the dry wind and the number of days that have passed with the dry season were calculated. In addition, the features of the distribution of the main climatic indicators in the East Kazakhstan region were described. According to the results of the study, during the year favorable meteorological conditions for dry wind are formed in the period from April to November, and the phenomenon of dry wind occurs in May-September. According to the results of calculations, on average, during the warm period of the year in the east of Kazakhstan, the number of favorable conditions for dry wind reaches 60 days, and the number of cases with dry wind reaches 30 days. And in mountainous areas, where there is no shortage of humidity, dry wind is not observed (MS Markakolsky Reserve, Leninogorsk). The areas where the dry wind phenomenon is most often observed correspond to flat and low-mountainous areas with low relative humidity and high wind speed (MS Akzhar, Ayagoz). The results obtained during the research work can be used by specialists working in the field of agriculture, climate research and forecasting of dangerous agrometeorological phenomena.

The Syrdarya River is the second largest river in the Aral-Syrdarya basin. It flows through the densely populated southern region of Kazakhstan and flows into the Aral Sea. The available water resources of the river are mainly used for irrigation of agricultural land. The main obstacle to the development of this branch of the economy is the lack of water in some parts of the massif, especially in its lower reaches. The article is devoted to the water regime currently forming in the lower reaches of the Syrdarya River, and the assessment of the change in runoff over the year. In modern conditions, as a result of the influence of economic activity on the flow of the Syrdarya River, it is difficult to clearly determine the type of river nutrition. It follows from the analysis that in all seasons of medium and low (low) water content, the values of the flow volume are close to each other. Also, the intra-annual flow distribution differs from the Central Asian rivers of a natural nature. For example, if in the natural conditions of the river the greatest Runoff is observed in March-July, then in modern conditions the period of abundant water falls on the winter period – November-February. The average monthly minimum water flows occur during surface irrigation of cultivated areas, that is, in the summer months, and in the fall there is abundant irrigation of rivers. The large Toktagul and Andijan reservoirs built in the upper reaches of the river for irrigation purposes also have a great influence on the intra-network distribution of runoff and the dynamics of its fluctuations. This is due to the fact that currently these reservoirs are actually used for energy purposes. In addition, in recent years, the Koksarai counterregulator has been built along the Syr Darya River in Kazakhstan.The main purpose of the study is to clarify the intracellular distribution of runoff in the lower reaches of the river in such difficult hydrological conditions in the river basin.
