ARMENIA Akhuryan Basin Management Area KEY WATER ISSUES EEnvi ronmenPt al Pr otectioIn of IntRe rnati onal RivBe r Basin s The project is funded This project is implemented by a consortium by the European Union led by Hulla & Co. Human Dynamics KG The Environmental Protection of International River Basins (EPIRB) project aims to improve the quality of water in transboundary river basins in the wider Black Sea region and Belarus, including Armenia. One of the specific objectives is to improve technical capacities by developing river basin management plans (RBMPs) in selected pilot river basins, according to the requirements of the EU Water Framework Directive (WFD). One of the selected pilot basins is the Akhuryan basin management area, which includes the Akhuryan River basin, located in the western part of the Republic of Armenia, and the Metsamor River basin, which is adjacent to the Akhuryan River basin. 2 Good water status The Water Framework Directive is achieved when pollution is and river basin management plans controlled and there is One of the requirements of the WFD is the achievement and sufficient flow for ecosystems preservation of good water status by managing waters in natural to function and survive. units — that is, in river basins. River basin planning follows a structured approach: finding out facts, deciding on necessary actions, making a management plan, and putting the plan into practice. An important first step is to identify significant water management issues so that appropriate solutions and measures can be developed. The impacts of human activities Human activities can lead to serious problems in terms of both water quality and quantity. The most common water-related problems are pollution and the effects of physical modifications to rivers and lakes. Water pollution can arise from two types of sources: point sources, such as discharges from industrial facilities and wastewater treatment plants; and diffuse sources, such as land- use activities, including agriculture. Hydromorphological alterations include the physical modification A river basin is the land of waterways, such as engineered modifications to the natural that water flows across or structure or flow of rivers in order to make particular use of them. under on its way to a river. The Such modifications might include land drainage, the construction basin sends all the water that of flood defences, or the damming of rivers to provide storage for falls within it to a central river power generation. or estuary. Another potential problem is excessive water abstraction, which can reduce river flow and even cause rivers and lakes to dry up. 3 AKHURYAN BASIN Russian MANAGEMENT AREA – Profile Federation TOTAL AREA Akhuryan - Metsamor Pilot Basin 2 5,021.19 km Larger Akhuryan - Kars Basin Black Sea LOCATION Georgia The Akhuryan River basin in western Armenia, bordered by the Metsamor River basin.

WATER USE Water abstraction, as of January Armenia 2014, according to water use permits: Turkey Azerbaijan irrigation 73.7%; hydropower 18.9%; household drinking water supply 3.3%; fisheries 2.7%; industries 1.4%. Iran DID YOU KNOW? Ample water reserves and good climatic conditions allow agriculture and cattle breeding to be key components of the regional economy. 4 The Akhuryan basin management area — Water challenges POLLUTION FROM WASTEWATER Water pollution AND INDUSTRIAL DISCHARGES is the contamination of surface waters and What’s causing the problem? groundwater with harmful Communal wastewater collection is not carried out appropriately, substances, causing a allowing organic and inorganic pollutants to enter the rivers. degradation in water quality. Wastewater from the food industry enters the rivers through the sewerage system, posing a significant threat to water quality. Water draining from the iron and molybdenum ore deposits in the Ashotsk region, along with the extraction and processing of construction materials, are further significant point sources of pollution. How does it affect water status? The introduction of untreated wastewater causes a rise in the level of phosphorus, nitrogen and organic compounds. The quality of the Akhuryan River downstream from Gyumri and the Karkachun River, and the quality of the Metsamor River below the towns of Armavir, Talin and Metsamor, are particularly threatened. Industrial activities result in high concentrations of hazardous substances such as arsenic, titanium, nickel, chrome and molybdenum in waters in the pilot basins. 5 POLLUTION FROM AGRICULTURE AND LIVESTOCK PRODUCTION What’s causing the problem? Agriculture is one of the leading branches of the economy in the Akhuryan basin and mainly comprises crop production and livestock rearing. Cattle and sheep farming are traditional activities and pastures occupy 55 percent of the river basin. Over the past 10 years there has been an increase in the number of livestock. Manure from farms is washed into surface waters and infiltrates groundwater resources, posing a significant threat to its quality. How does it affect water status? Pollution from cattle breeding leads to increased concentrations of nitrogen, phosphorus and organic compounds, particularly in the Akhuryan and Karkachun Rivers and in the Metsamor River basin. This rise in nutrients causes a rapid growth in algae, known as algal bloom, which affects water quality and biological oxygen demand, also endangering the quality of groundwater. The explosive growth of algae and plants changes the composition and condition of freshwater in a process known as eutrophication. Oxygen is used up as the dead algae decompose, reducing the amount of dissolved oxygen in the water and altering the survival, Manure can be a valuable reproductive and competitive capacities of water organisms. Algal resource rather than just a bloom can be harmful to fish and other aquatic animals, as it waste product, but it must be creates toxins. Even non-toxic algal blooms can affect aquatic life by managed appropriately to blocking out sunlight and creating areas with little or no oxygen. protect surface waters and groundwater. 6 HYDROMORPHOLOGICAL ALTERATIONS AND WATER ABSTRACTION Hydromorphology What’s causing the problem? combines study of the In the lower section of the Akhuryan River, below Lake Arpi, about hydrological regime and of 11 km of the river (from the settlement of Berdashen to Pokr morphological conditions. It Sepasar) is diverted through an earthen canal. There are currently deals with the quantity and eight small hydropower plants (HPPs) operating in the Akhuryan dynamics of water flow, as well River basin, and three more are under construction. as the shape and boundaries of a particular water body. In the lower reaches of the Metsamor River basin, particularly in Armavir province, fish farming has increased significantly in recent years. How does it affect water status? The diversion of the Akhuryan River through the canal has altered the natural flow of the river. Although small, the HPPs put significant pressure on water resources, as the river’s ecological flow cannot be maintained in some sections. The ecological flow is the flow necessary to sustain ecosystem functions. Where HPPs have been constructed, the ecological flow must reach a certain percentage of the annual mean daily discharge in order to ensure the preservation of the river’s ecosystems. Water abstraction for fishery purposes also puts significant pressure on groundwater resources in the southeastern part of the Metsamor River basin, as well as on the flow of the Metsamor River. 7 This publication summarises a review of the pressures and impacts on water bodies in the Akhuryan basin management area, prepared in the framework of the EPIRB project.
