Abstract. The analysis of spatial and temporal regularities of the annual runoff of the transboundary river Alazani (Ganikh), which flows through the territory of Georgia and Azerbaijan, has been carried out. The series on the average annual water discharge of 6 hydrological gauges for the period from 1925 to 2017/2019 was used. It was found that for the researched rivers, the fluctuations of the average annual water discharges are in phase, however, the absence of strict synchronicity in the fluctuations of the annual runoff leads to a decrease in the spatial correlation coefficients. In the studied series of river Alazani (Ganikh) both on the territory of Georgia and Azerbaijan, there is no trend; however, for a number of annual runoff of the Ayrichai River, the main tributary of the r. Alazani (Ganikh), a significant positive trend was revealed. It should be noted that the reason for the nonstationarity is the climate change, the impact of which on runoff has become noticeable in recent decades. It was found that the variance of the second half of the analyzed series increased. The annual runoff of the Alazani (Ganikh) River has changed very little over 1991-2017 / 2019 compared with the period 1961-1990. For the Ayrichai River, the second period is characterized by increased water content. Keywords: River Alazani (Ganikh), Annual runoff, Water discharge, Transboundary river, Runoff change.

Abstract. The article is devoted to the analysis of long-term fluctuations of the annual flow of the Shirvan rivers. The analysis used data from 4 rivers with an observation period of more than 50 years. linear trends were identified in the observation series, and their significance was assessed. The annual water discharge observations are divided into two series, covering 1961-1990 and 1991-2018. The dynamics of annual precipitation data of meteorological observation stations located in the study area were also analyzed. Annual precipitation increased in Goychay and Ismayilli meteorological stations, and partial decrease in Gabala and Oguz meteorological stations. The seasonal variation of the annual flow is also analyzed. According to data of Alijanchay and Girdimanchay, a decrease in annual flow was observed, and an increase was observed in Goychay and Turyanchay rivers. The seasonal fluctuations of the flow increased in the cold seasons and decreased in the warm seasons. Keywords: annual flow, long-term fluctuations, linear trends, climate changes

Abstract: Since the very beginning of tourism, nature has been the main driving force behind travel. Obviously, natural monuments are one of the attractive places for tourists. Today ecotourism based on natural monuments and attractions has become one of the leading sectors of the economy in many countries of the world. Travels associated with natural monuments are now the most promising and intensively developing areas of recreational activities.

Abstract: The article examines the impact of global climate change on rainfall regimes in lankaran natural province. The study used rainfall and temperature monitoring data from 5 meteorological stations registered for 1991-2016. Different (month, section, seasonal, and annual) rainfall indicators were compared with the same quantities of 1961-1990. Multiculturalism was examined over two periods (1991-2004-I, 2005-2016-II). based on the research, the average annual temperature in the province over the past 25 years is 14-16°C at the coastal and adjacent stations, 11-13°C in the lowlands, and 8-10°C in the middle. however, the average annual temperature has increased by 0.7°C compared to 1961-1990. Over the years, precipitation has been distributed over a wide range (330-1220 mm), depending on the stations. During the period from 1991 to 2016, annual rainfall increased slightly at Kelvez station, but decreased by 9% compared to the norm at other stations (1961- 1990). Keywords: Climate change, mitigation, concentration, ecodynamics, amplitude, evolution, norma value, correlation, interpolation, trend.

Abstract: The increase in temperature is accompanied by a decrease in precipitation in some regions of the globe, an increase in the frequency of droughts. In this case, of course, the threat of a decline in agricultural productivity is inevitable. Of course, in some regions, the opposite process can occur, ie it can lead to an increase in temperature, increased precipitation and a decrease in the tendency of droughts. In this case, productivity increases. The article clarifies the factors that affect the increase and decrease of productivity. Keywords: trend, angle coefficient, drought, productivity

Abstract. hovsan Aeration Station provides treatment and processing of wastewater in baku. The amount of annual sludge here reaches 2 million cubic meters. These sludges contain complex multicomponent substances of organic and mineral origin. Taking this into consideration, we analyzed surplus sludge that generated during the technological process at hovsan Aeration Station. The studied surplus sample is a substance that is thickened in the mechanical workshop of the station, and then the substances are dehydrated in a centrifuge. They consist of a complex polydisperse system. The study of surplus sludge formed during the technological process at hovsan aeration station revealed that the main component of sludge consists of organic substances. The mineralogical composition is dominated by silicon dioxide and magnesium calcite. Keywords: wastewater, surplus sludge, mineral service, organic matter
