The cultural landscape of the Sonoran Desert, one of the largest North American deserts, has changed greatly over the last five centuries. Five selected vignettes illustrate the changing human perceptions and uses of the desert's limited water
supplies and plant species, from pre-Columbian times to the twentieth century. Author sees dwindling water supplies causing major lifestyle changes in the future. - (SLD)
The effects of forest diching and water level changes on sediment quality in a small lake, Perhonlampi, Central Finland

The aim of this paper was to explore the effects of ditching and natural/artificial water level changes on sedimentation, total metal, P and S concentration and speciation of Cu, Fe, Mn and Zn compounds in a small lake. The clearest geochemical
A study was carried out on a structured soil in the south-east of Ireland to investigate flow patterns of water in soil. The results provided preliminary evidence for preferential flow in the soil. Nitrate leaching data, from a grazing study, tended

Hydrological processes and water resources in the face of global climate change
Aquatic ecosystem ; Climatic warming ; Ecosystem ; Geochemistry ; Global change ; Heavy metals ; Pollution ; Water quality
The forecast climatic warming will cause hydrological changes on Earth which will be accompanied by changes to the chemism and quality of waters. On account of their wide-spread occurrence and permanence, it is heavy metals in the bottom sediments
of surface waters which pose the greatest endangering to the natural environment. Once introduced into it, they cannot be removed, and can in suitable conditions be released from bottom sediments and give rise to secondary pollution of waters in their soluble

In the Rocky Mountains, the association of increases in acidic deposition with increased loading of sulfate and direct changes in surface water chemistry has been reported by several AA. In alpine areas of the Colorado Front Range, modest loadings
of N in deposition have been associated with leakage of N to surface waters. The question remains of whether NO3 is being exported to surface waters on the Colorado western slope during snowmelt runoff. Landscape type appears to be important in leakage
of N to surface waters, which is associated with basins having steep slopes, thin soils, and large amounts of exposed bedrock.
