Changes in climatic conditions for the formation of ice regime in the rivers of the Lake Sevan basin
Introduction. Studying the ice regime of Armenian rivers is a serious scientific and practical task due to the country’s unique climatic conditions. This article examines the potential impact of climate change on the properties and processes associated with river ice, discusses future results, and their implications. The Introduction. Studying the ice regime of Armenian rivers is a serious scientific and practical task due to the country’s unique…
Forecast of ice phenomena on the rivers of the lake Sevan basin
Introduction. The study of ice conditions on rivers is an important task to ensure safe navigation, the operation of a number of hydraulic structures, the laying of oil and gas pipelines, as well as to minimize economic damage from dangerous ice phenomena, which are often accompanied by significant flooding of the territory (floods). One of the main types of ice forecasts can be attributed to forecasts of the timing (dates) of the beginning and e…
Assessment of soil agrophysical and agrochemical changes under different tillage methods
The article discusses the results of studies of changes in winter wheat yield depending on the agro physical and agrochemical properties of the soil with various methods of tillage and the application of soil improvers (vermicompost, mineral fertilizers, bentonite). Field and laboratory studies have shown that the distribution of soil organic matter and macronutrients available to plants varies in the depth of arable horizons, depending on the me…
The Influence of Cultivation, Storage and Processing Technology on the Nitrate Content in Potato Tubers and Vegetable Crops as the Example of Ecologically and Hygienically Oriented Organic Agricultura…
The article presents the results of studies of the influence of organic and mineral fertilizers, as well as storage and processing technologies on the level of nitrates in potatoes, carrots and cabbage. The study demonstrated that in order to obtain the high yield of environmentally friendly vegetable crops, it is necessary to use biohumus at a norm of 8 t/ha or the combination of 6 t/ha biohumus and N35P35K40. This treatment can provide the pota…
Long-term assessment of the minimal winter runoff regime of rivers in the lake Sevan basin under climate change
Introduction. Analysis and assessment of the statistically significant consequences of climate change for the long-term minimum 30-day winter runoff of rivers in the Lake Sevan basin is of significant interest to consumers and water resource management, being an important hydrological issue. The relevance of consideration of the issue is due to the fact that for Armenia Lake Sevan is a strategic reservoir of fresh water, a large water management …
Assessment of the current state of the hydrochemical regime and water-environmental problems of the basin of the Gavaraget River flowing into Lake Sevan
The results of studies of the current hydro-chemical state and water-ecological problems of the Gavaraget River basin, which flows into Lake Sevan from the north-west, are presented. Extreme water discharge, ten-day flow, ecological output have been determined, water-ecological features have been identified, long-term dynamics of the main indicators characterizing the ecological state of the Gavaraget River, spatial-temporal changes in winter and…
On the features of the spatio-temporal variability оf the heat waves characteristics of the last three decades (Ararat valley, Armenia)
The aim of this work to study, identify the repeatability and duration of heat waves of the study area. For it were suggested and decided the following tasks: Findings. The study of regularities of variability of the spatial-temporal distribution of characteristics of heat wave in conditions of regional and global changes of climate is current task of modern geographical science. Extremely high temperatures and heat waves of study area excessivel…
On assessment and management of hydrological risks during spring flood in the River Arpa Basin (Republic of Armenia)
Introduction. Issues of formation of maximum expenses and their forecast, risk extreme flow rates on the rivers of Armenia represents a significant interest for consumers of water resources. The works of scientists of the Republic of Armenia are devoted to the solution of this problem: (Vardanyan T. G., Muradyan Z. Z., 2014), forecasting the maximum water flow for the Jermuk hydrological station on the Arpa River (Misakyan A. E., Azizyan L. V., A…
