Major River Systems in the Arctic Major River Systems in the Arctic
The Arctic has several of the world’s largest rivers.This graphic shows the major river systems of the Arctic and their annual discharges in cubic kilometres, and the catchment area of the Arctic Ocean. The major river systems shown are the Mackenzie, Yukon, Nelson, Kolyma, Indigirka, Lena, Kotya, Yenisey, Ob, Pechora, Severnyy and Dvina.

Urban water cycle Urban water cycle
This graphic illustrates the impact of human activity on groundwater. It shows that groundwater is obtained from periurban wellfields and urban wells, then used and disposed of as wastewater through pluvial drainage, piped sewage and on-site sanitation and industrial effluent disposal. It also shows that wastewater is treated and then reused for irrigation, with excess flows re-entering the aquifers.

Human activities leading to coastal degradation Human activities leading to coastal degradation
Physical alteration and destruction of habitats are now considered one of the most important threats to coastal [and marine] areas. This graphic shows the extent to which twelve different human activities cause environmental degradation in estuaries, inter-tidal wetlands and the open ocean. The activities include the drainage of coastal ecosystems; the construction of dykes, dams and seawalls and the mining of wetlands.

Urban water supply and wastewater on a shallow aquifer Urban water supply and wastewater on a shallow aquifer
This graphic shows the changes in water supply and wastewater disposal that occur through four stages of growth of a settlement: early settlement; the town becomes a city; the city expands and the city expands further. The changes include increased groundwater pollution and changes in pluvial drainage, the water table and wellfields.

The Caspian Sea drainage basin The Caspian Sea drainage basin
The Caspian Sea runs north and south, extending over 1,200 km, with an average width of 320 km. It covers approximately 400,000 sq km (an area slightly larger than Germany). The population of the region is about 14 million, distributed over the coastal provinces of five countries: 6.5 million in Iran, 3.9 million in Russia, 2.2 million in Azerbaijan, 0.8 million in Kazakhstan and 0.4 million in Turkmenistan.

Baltic Sea drainage basin Baltic Sea drainage basin
This 'basemap' displays the extent of the drainage basin (the boundary for the water that ends up in the Baltic Sea), and the countries in the region. The drainage basin represents all water that drains into the sea, through rivers and ground water.

Land cover - Baltic Sea region (BALANS) Land cover - Baltic Sea region (BALANS)
The Baltic Sea region is covered by primarily forested land and cropland. This land cover map, delineated for the Baltic Sea drainage basin, is using the dataset prepared through the BALANS project, and represents the situation around year 2000.

Wetlands in the Baltic Sea drainage basin Wetlands in the Baltic Sea drainage basin
Percentage of wetlands out of total land area (by grid cell) for the Baltic Sea drainage basin. Wetlands acts as buffers in cases such as antropogenic nutrient releases (which leads to eutrophication) and acidification. The ratios have been estimated from various sources, and resembles the situation at approximately 1990.

Mining and ore waste Mining and ore waste
Mining waste takes up a great deal of space, blights the landscape and often affects local habitats. By its very nature it can constitute a serious safety hazard. Poor management may allow acidic and metals containing drainage to the environmnent, it can result in contaminated dusts be spread by the wind, and can also pose a physical risk. Indeed, the failure of structures such as dams built to contain mining waste has lead to many accidental sp...

Ice sheets, schematic illustration for Greenland and Antarctica Ice sheets, schematic illustration for Greenland and Antarctica
The ice cover in Greenland and Antarctica has two components – thick, grounded, inland ice that rests on a more or less solid bed, and thinner floating ice shelves and glacier tongues. An ice sheet is actually a giant glacier, and like most glaciers it is nourished by the continual accumulation of snow on its surface. As successive layers of snow build up, the layers beneath are gradually compressed into solid ice. Snow input is balanced by glaci...
